What is the resulting formula unit when calcium (ca) and sulfur (s) bond?

CaS

Explanation:

Calcium is a metal from Group 2, so it has 2 valence electrons. Sulfur is a non-metal from Group 16, so it has 6 valence electrons. Metals and non-metals form ionic bonds, in which metals lose electrons and non-metals gain electrons. In both cases, they follow the octet rule, trying to have the electron configuration of the closest noble gas, which has its valence shell complete with 8 electrons.

Calcium has 20 electrons and loses 2 electrons to have the electron configuration of Ar and form Ca²⁺.

S has 16 electrons and gains 2 electrons to have the electron configuration of Ar and form S²⁻.

In the formula unit, one atom of Ca²⁺ bonds to one atom of S²⁻ to maintain electroneutrality and form CaS.

the movie was based there, and all the animals and characters are native.

it would be a gas formation
