That is phosphorus trichloride and a COVALENT BOND
Cl needs one electron and P has metallic character, it donates electron easy
<span>As the number of electrons added to the same principal energy level increases, atomic size generally A. increases.
</span>
<span>Because
as you add energy levels, the electrons are drawn to the nucleus of the atoms giving them a
lesser charge. Thus its atomic size also increases. </span>
When sulfur reacts with zinc metal is forms a compound known as zinc sulfide.
<h3>
Name of the elements</h3>
The names of the elements that make up the compound will be determined from the atomic mass of the elements.
<h3>Which element has atomic number 30</h3>
The element that atomic number of 30 is zinc and it has oxidation number of +2.
<h3>Which element has atomic number 16</h3>
The element that atomic number of 16 is sulfur and it has oxidation number of -2.
<h3>Chemical reaction between sulfur and zinc metal</h3>
Zn²⁺ + S²⁻ --------> ZnS
Thus, when sulfur reacts with zinc metal is forms a compound known as zinc sulfide.
