Alr u see. argon is in group 8 of the periodic table, also known as noble gases. noble gases all have full shells, octect. this means that there is no chance for covalent or ionic bonding, no valence electrons available to bonding.
however, chlorine is in group 7 of the periodic table. this means to obtain a full octect shell, they will have to undergo covalent bonding to form a full octect shell.
hence, argon is more stable compared to chlorine
Answer:
Sodium is more reactive than lithium because as we move down a group it is easy to lose electrons as the number of shells increases and nuclear charge decreases. As valence electrons take part in chemical reaction and its easier to lose electrons as we move down a group chemical reactivity increases. Therefore, sodium is more reactive than lithium.

Answer:
1.054 x 10²⁴ molecules
Explanation:
In order to convert moles <em>of any given substance</em> into a number of molecules, we need to use <em>Avogadro's number</em>, which states the number of molecules -or atoms, in the case of elements- present in one mol:
- In one mol there are 6.023x10²³ molecules.
We now <u>convert 1.75 moles into molecules</u>:
- 1.75 mol * 6.023x10²³ molecules/mol = 1.05x10²⁴ molecules
Five valence electrons for one nitrogen and 10 valence electrons for two nitrogens
