Answer:
Fluorine element has less orbitals than chlorine.
Explanation:
They are both in the same group so they have to gain the same amount of electrons(which will not effect shape)....However on going down the group one notices that the atoms get larger as more orbitals are needed to hold the electrons.
Answer:
<em><u>The compound hydrogen chloride has the chemical formula HCl and as such is a hydrogen halide. At room temperature, it is a colourless gas, which forms white fumes of hydrochloric acid upon contact with atmospheric water vapor. Hydrogen chloride gas and hydrochloric acid are important in technology and industry. Hydrochloric acid, the aqueous solution of hydrogen chloride, is also commonly given the formula HCl.</u></em>

Answer:
A) Radium
i don't think that group 2 has period 7, it has only up to period 6 so it's probably Radium :))
Synthetic fertilizer
<h3>What is Birkeland and Eyde's process?</h3>
It is a process developed by two scientists - Kristian Birkeland and Sam Eyde - to fix atmospheric nitrogen for the production of fertilizer.
The nitrogen oxide produced is then used in the production of nitric acid and eventually, the production of synthetic fertilizer.
First, nitrogen is fixed into nitrogen oxide:
Then, the NO is oxidized:
The nitrous oxide produced is then dissolved in water to form nitric acid:
