How do you predict which bond is shorter?
The length of the bond is determined by the number of bonded electrons (the bond order). The higher the bond order, the stronger the pull between the two atoms, and the shorter the bond length.
An enduring attraction between atoms or ions known as a chemical bond is what allows molecules and crystals to form. The bond may be created by the sharing of electrons in covalent bonds or by the electrostatic attraction of two oppositely charged ions, as in ionic bonds. Covalent, ionic, and metallic bindings are examples of "strong bonds" or "primary bonds," whereas dipole-dipole interactions, the London dispersion force, and hydrogen bonding are examples of "weak bonds" or "secondary bonds." The sharing or transfer of electrons between the involved atoms results in strong chemical bonds.

Which atom in a water molecule is greedy for electrons, giving it a negative charge?
Oxygen atom in a water molecule is greedy for electrons, giving it a negative charge.
Because oxygen is more electronegative (electron-greedy) than hydrogen, it grabs electrons and keeps them away from the H atoms. This results in a partial negative charge on the oxygen end of the water molecule and a partial positive charge on the hydrogen end.
What is a molecule?
A molecule can be homonuclear, that is, it consists of atoms of one chemical element, eg two atoms in an oxygen (O2) molecule; or it can be heteronuclear, a chemical compound composed of more than one element, eg water (two hydrogen atoms and one oxygen atom; H2O). In the kinetic theory of gasses, the term molecule is often used for gaseous particles.

If an electricity producer decided to decrease the amount of carbon dioxide (carbon footprint) released by the power plant and reduce greenhouse gas emissions to zero, which of the following energy resources would no longer be an acceptable alternative?
A. hydroelectric power
b. biomass power
c. geothermal power
d.wind power
Answer:
NONE but the most accurate of your list will be: geothermal power
Explanation:
If an electricity producer decided to decrease the amount of carbon dioxide released by the power plant and reduce greenhouse gas emissions to zero, then none of the energy resources listed would be an acceptable alternative. This is because all of the listed energy sources, including hydroelectric power, biomass power, geothermal power, and wind power, produce some amount of greenhouse gas emissions, even if that amount is relatively small. The only way to achieve zero greenhouse gas emissions from an electricity-generating power plant would be to use a completely carbon-free energy source, such as solar or nuclear power.
What is a half-life time of a radioactive isotope?
Half-life is the length of time it takes for half of the radioactive atoms of a specific radionuclide to decay.
Radioactive atoms, of which the environment naturally contains a large number, are what cause ionising radiation. A radioactive atom can be found in the forms of a gas, liquid, or solid just like any other sort of atom. An electron cloud surrounds the atom's nucleus, which is made up of protons and neutrons.
Most atoms are stable because neutrons and protons are distributed evenly within them. Nevertheless, some atoms have an unstable proton-neutron ratio. Isotopes are variations of an element that have different neutron counts. Atoms seek stability; therefore, to transition from one stable state to another, they let go of energy from their nucleus in the form of particles or rays.

How and Why are element configurations written in terms of Noble gas configuration. Explain giving examples.
Answer:
In chemistry, the element configuration of an atom refers to the arrangement of its electrons in its outermost energy level, or valence shell. The element configuration is typically written using the symbols of the elements in the periodic table, and it is used to predict the chemical behavior of the atom.
One common way to write element configurations is in terms of noble gas configurations. A noble gas is a chemical element that is unreactive and stable due to its filled valence shell, and the noble gases are helium, neon, argon, krypton, xenon, and radon.
The reason why element configurations are often written in terms of noble gas configurations is that it makes it easier to predict the chemical behavior of the atom. For example, the element configuration of sodium is 1s22s22p63s1. This can be written in terms of the noble gas configuration of neon, which is 1s22s22p6, as [Ne]3s1. This notation indicates that the valence shell of sodium has the same electron configuration as the noble gas neon, plus one additional electron in the 3s subshell.
Similarly, the element configuration of chlorine is 1s22s22p63s23p5. This can be written in terms of the noble gas configuration of argon, which is 1s22s22p6, as [Ar]3d5. This notation indicates that the valence shell of chlorine has the same electron configuration as the noble gas argon, plus five additional electrons in the 3p and 3d subshells.
Therefore, element configurations are written in terms of noble gas configurations to provide a concise and easy-to-understand representation of the electron arrangements in the valence shells of atoms. This can help predict the chemical behavior of the atoms and aid in the understanding of the properties of chemical compounds.
Fill in the blank to make this statement true: (0,0) is a solution to _________ equation(s) in the form y=kx.
(0,0) is a solution to all equation(s) in the form y = kx.
When an equation is given in the form of y = kx, it shows direct variation, meaning that the y-intercept is 0. For example, lets take an equation in slope-intercept form, it has an equation of y = mx+b. Since there is an absence of "b", in the form y = kx, that means that the line must pass through the origin, or (0,0).
For any equation, (0,0) can be the solution if it is in the form of y = mx. Hence, the statement is (0,0) is a solution to all equation(s) in the form y=kx.

What is nitrogen fixation ?
Nitrogen moves from the atmosphere into the soil. Earth’s atmosphere contains a huge pool of nitrogen gas (N2). But this nitrogen is “unavailable” to plants, because the gaseous form cannot be used directly by plants without undergoing a transformation. To be used by plants, the N2 must be transformed through a process called nitrogen fixation. Fixation converts nitrogen in the atmosphere into forms that plants can absorb through their root systems.
A small amount of nitrogen can be fixed when lightning provides the energy needed for N2 to react with oxygen, producing nitrogen oxide, NO, and nitrogen dioxide, NO2. These forms of nitrogen then enter soils through rain or snow. Nitrogen can also be fixed through the industrial process that creates fertilizer. This form of fixing occurs under high heat and pressure, during which atmospheric nitrogen and hydrogen are combined to form ammonia (NH3), which may then be processed further, to produce ammonium nitrate (NH4NO3), a form of nitrogen that can be added to soils and used by plants.

when the lobes of two p orbitals are in the same phase and overlap side-by-side, the orbital that is formed has a _____ dissociation energy compared to the σ∗ molecular orbital formed from the out-of-phase direct overlap of the two p orbitals.
The orbital that is created when the lobes of two p orbitals overlap side by side while being in phase with one another has a lower dissociation energy than the molecular orbital created when the two p orbitals are directly in phase with one another.
What do you call it when two atoms share electrons and overlap their electron shells to form a molecule?When two atoms share a pair of electrons, a covalent bond is created. The electron pair is drawn to both of the nuclei, which keeps the atoms together.
Exactly what kind of orbital overlap produces the strongest covalent bond?The strongest bond is produced by the head-on overlapping of 2p2p orbitals because the electron density is highest along the bond's axis.
