Question

sulfur (s) is in group 16 on the periodic table. if sulfur were to bond covalently with another element, how many bonds will it form to become stable?
8 bonds
2 bonds
6 bonds
question 23

the alkaline earth metal beryllium (be) engages in a chemical reaction and loses all of its valence electrons.
what charge does beryllium have after the chemical reaction?

Explanation:

Step1: Determine valence electrons of sulfur

Group 16 elements have 6 valence electrons. To achieve a stable octet (8 - electron configuration), sulfur needs \(8 - 6=2\) more electrons. Each covalent bond provides 1 electron. So, sulfur forms 2 covalent bonds.

Step2: Determine charge of beryllium

Beryllium (Be) is in group 2. Group 2 elements have 2 valence electrons. When it loses all valence electrons (2 electrons), it has \(2\) more protons than electrons. So, its charge is \(2+\).

Answer:

For the sulfur question: 2 bonds.
For the beryllium question: \(2+\).
