covalent bonds form because...
o two atoms share their electrons.
o two ions of different charges are electrically attracted to each other,
o two or more atoms share protons.
o two ions of the same charge are electrically attracted to each other.

when naming a covalent compound, you should
o always add prefixes to both nonmetal names, without exceptions
o add prefixes to both nonmetals, with the exception of mono - on the first nonmetal
o only add prefix to first nonmetal
o only add prefix to second nonmetal

Explanation:

Question 10

Covalent bonds are formed when two atoms share electrons. Ionic bonds form when two ions of different charges are attracted (eliminating the second option). Atoms do not share protons (eliminating the third option). Ions of the same charge repel, not attract (eliminating the fourth option).

When naming covalent compounds, prefixes are added to both non - metals. However, the prefix “mono -” is not used on the first non - metal (e.g., \(CO_2\) is carbon dioxide, not monocarbon dioxide). The first option is incorrect as there is an exception for “mono -” on the first non - metal. The third and fourth options are wrong because prefixes are added to both (with the mentioned exception for the first).

Answer:

two atoms share their electrons.
