Answer:
the element must be in the fifth, sixth, or seventh energy shells.
Explanation:
Because the first ionization energy is less than calcium's, the element must be larger and in the next energy shell. Calcium is in the fourth energy shell, so the element must be in the fifth, sixth, or seventh energy shells.

Answer:
9.8 m/s/s
Explanation:
The magnitude of the acceleration due to gravity, denoted with a lower case g, is 9.8 m/s2. This means that every second an object is in free fall, gravity will cause the velocity of the object to increase 9.8 m/s. So, after one second, the object is traveling at 9.8 m/s.

The energy needed to break the bonds of 2 moles of O2 gas would be 968 jk/mol.
<h3>What is a chemical bond?</h3>
A bond is a term that refers to the attractive interaction between atoms and molecules.
The energy needed by moles to interact is measured in joules per mole and is represented as follows:
In the case of O2 moles, they require 494 jk/mol, therefore, if we need to separate 2 moles of O2, we need 968 jk/mol.
