What kind of information can we read from the period system? How was it built up?

Answers

Answer:

Explanation:

Periods correspond to the relationship of orbitals, or likely areas in which electrons will be found, inside the outermost shell of the atom. Successive periods down the table correspond to atoms with a more electron-rich core of inner shells.

What kind of information can we read from the period system? How was it built up?

Answers

Answer: the information we can get from looking at the periodic table includes but is not limited to: the shape of electron orbitals, electron configuration, and mass of the elements. and here is what I know about how it was formed:

Explanation: as far as i know, one of the first periodic tables of the elements consisted of four elements: water, fire, earth, and air (None of these are actual elements though). One of the next ones had 33 elements, separated into four categories: games, metals, earth's, and non-metals. The final and most up-to-date version of the periodic table (or, these are the categories that mine has) has 118 elements split ugames. 7 groups (columns) and 18 periods (rows) these categories: alkali metals, alkaline earth metals, lanthanides, actinides, transition metals, post-transition metals, metabolism, reactive nonmetals, and noble gases.

First question, periods correspond to the relationship of orbitals, or likely areas in which electrons will be found, inside the outermost shell of the atom. Successive periods down the table correspond to atoms with a more electron-rich core of inner shells.

Second question, British chemist John Newlands was the first to arrange the elements into a periodic table with increasing order of atomic masses. He found that every eight elements had similar properties and called this the law of octaves. He arranged the elements in eight groups but left no gaps for undiscovered elements.

What information does the periodic table give you?

Answers

Hi,
The periodic table contains information about each of the known elements. It includes the name of each element, its atomic number, its atomic mass and its chemical symbol.

The periodic table is divided using groups (columns) and periods (rows).

Each specific group or period has a specific pattern in the elements.

The modern periodic table is arranged in order of increasing atomic number.

I’m not really sure what information what you were asking for but I hope this helps..
Hello!
The modern periodic table was created by Dmitri Mendeleev with the main goal of showing rows and columns with a logic arrangement of chemical elements.

In each column, the groups, the elements have the same number of electrons in the outermost shells. While the rows are called periods or series.


A student wants to determine the effect of mass on kinetic energy. She will drop two balls of the same size into a pool of water. Which investigation method should the student use?(1 point)

a. She should drop two balls of the same mass from different Hights.
b.she should drop two balls with different masses from the same Hights
c.she should drop two balls with different masses from different Hights
d.she should drop two balls of the same mass from the same Hights

Answers

I think the answer is C
I believe the correct answer is B. Not only because she wants to test different masses but dropping it for the same hight is the correct way to preform an experiment

For this assignment you need to create reduction from Circuit Value Problem (cvp) to Context Free Grammar Membership problem. Your code should take a circuit written as a logical statement and a list of zeros and ones corresponding to the input of the circuit. Afterwards your code should return a context free grammar on Chomsky normal form and a string that can be put on the cyk algorithm. (100) - The circuit is going to be binary so any gate can only take 2 inputs and output 1 value. Also any output can only go into one gate or it can be the output of the circuit. - For this problem we are going to ignore the "not" gate so the given circuits can only have "or" and "and" gates. - When a circuit is written as a logical statement we are going to use "+" sign to represent "or" gates and "*" sign to represent "and" gates. - In the logical statement all inputs are going to be represented with an "x" followed with a number. This number can be more than 1 digit. An example "12". - The biggest circuit your code can receive consists of 25 inputs and 50 circuits. - Your code doesn't need to be efficient but if it is running on linear time, it will receive 20 extra points. - Here is an example circuit written as a logical formula:((x1+x2) 3)+(x4 5) merchandise management is one aspect of customer service that should be carefully managed for the reasons listed except which one? triangle ABC is being enlarged using a scale factor of 1/2 and center (1,9) to give triangle A' B' C' HELP ASAP.
