The overall charge of an ion is determined by how many electrons it has gained or lost. A negative overall charge results from an atom gaining electrons.
When electrons are obtained, what happens?Atoms that lose an electron change into positive ions, often known as cations. Atoms transform into negative ions, or anions, when they pick up electrons.
How are the acquired electrons located?If the charge is negative, the atomic number is increased by the charge. If it's negative, the ion has picked up electrons. The total number of electrons can be calculated by multiplying the atomic number by the charge. Protons are less numerous than electrons in this instance.

Hydrogen peroxide is a colorless liquid at room temperature with a bitter taste. Small amounts of gaseous hydrogen peroxide occur naturally in the air.
Since it easily breaks down into oxygen and water and releases heat, hydrogen peroxide is unstable. Despite not being flammable, it has a strong oxidising agent that, when in contact with organic material, can trigger spontaneous combustion. For medical purposes, as well as for usage as a clothing and hair bleach, hydrogen peroxide is present in many homes in low amounts (3–9%). Higher quantities of hydrogen peroxide are employed in the manufacturing of organic compounds, foam rubber, and rocket fuels in addition to being utilised as a bleach for paper and textiles.
With disinfecting, antiviral, and antibacterial properties, hydrogen peroxide is a peroxide and oxidising agent. Hydrogen peroxide's oxidising activity manifests itself upon topical administration, rinsing, and generation of free radicals, which causes oxidative damage to proteins and other biological molecules.

α and β rays consist of particles, whereas γ rays are high-energy radiation and contain no particles and thus they have no mass. Given that the penetrating power decreases with mass, rank the rays according to their penetrating power. Rank the components from strongest penetrating power to weakest penetrating power.
Therefore, the following is the order of penetrating power:
The most powerful penetrating force is gamma () rays.
Between gamma and alpha rays are beta() rays.
Alpha(a) rays have the lowest penetrating power.
What is penetrating power ?
The penetration power of each form of radiation describes how well it may penetrate solid objects. The radiation's penetration power increases with the amount of material it can penetrate, making them more harmful.
Gamma rays is a photon, and it is a ray, while alpha and beta are particles. The least invasive particles are alpha rays. A sheet of paper or a few inches of air will stop them.

A species known as a carbocation is one in which a molecule's carbon atom has less than eight protons and a positive formal charge. It is frequently thought of as an intermediary in different reaction pathways. From tertiary to secondary to primary, carbocations lose stability.
The top structure is created when the hydrogen from HBr (explicitly depicted) is linked to the secondary carbon that was previously carrying the double bond. As a result, a tertiary carbocation will occur. The bottom structure, where the tertiary carbon contains the hydrogen and charges the secondary carbon positively, is the less stable intermediate.

nitrogen monoxide is produced by combustion in an automobile engine. what volume of nitrogen dioxide is produced when 12.0 liters of nitrogen monoxide react according to the following reaction? (all gases are at the same temperature and pressure.)
41.2 litres of Nitrogen dioxide will be produced.
28.9g NO x (1 mol NO / 30.01g NO) = 0.963 mol NO
0.963 mol NO x (1 mol O2 / 1 mol NO) = 0.963 mol O2
0.963 mol O2 x (31.98g O2 / 1 mol O2) = 30.8g O2
30.8 grams of oxygen gas are required for the complete reaction of the 28.9 grams of nitrogen monoxide.
Charles' law states that the volume of a given gas sample under constant pressure is precisely proportional to its absolute temperature. Boyle's law states that, for a given amount of gas and constant temperature, the volume is inversely proportional to the pressure.
