Answer:
The names of the electron shell were given by a spectroscopist named Charles G Barkla. He named the innermost shell has k shell because he noticed that the X-rays emitted two types energies. These energies were named as type A that is higher energy X-ray and type B that is lower energy X-ray. Later these energiers were named with different alphabets. He noticed that K type X-rays emitted the highest energy. Therefore, he named the innermost shell as the K shell.

The answer is: a. The number of sodium ions is equal to the number of formula units of salt.
Balanced chemical equation: Na⁺ + Cl⁻ → NaCl.
Formula unit is the representative particle of an ionic compound. It is lowest whole number ratio of ions in an ionic compound, for sodium chloride it is NaCl.
In this chemical equation one sodium cation and one chlorine anion form one sodium chloride formula unit.
The number of protons in an atom of krypton is 36.
<u>Explanation:</u>
The number written above the symbol of Kr in the periodic table represents the atomic number of the element . Then the number written in the below represents the mass number.
So the mass number of krypton is 84 and the atomic number of krypton is 36. As it is known that number of protons and electrons will be equal in a stable element. Thus, the krypton atom will be having 36 protons.
There is inverse relationship between independent and dependent variables of this experiment.
<h3>What relationship exists between the independent variable and the dependent variable?</h3>
According to the data, there is inverse relationship exists between the independent variable and the dependent variable because when more sugar is added crystallization does not occur.
So we can conclude that there is inverse relationship between independent and dependent variables of this experiment.
