Answer:

Both electrons of Mg should be transferred to one O.

Explanation:

This is because metals like to lose electrons whereas non metals like to gain electrons in an ionic compound. MgO is an ionic compounds. So Magnesium being a metal in group 2 of periodic table, it wants to donate 2 electrons to get to the octet rule, so it donates its electrons and oxygen accepts them to fill its octet rule.

Answer B

Mg has a positive ionic charge because it hoped to loose its two electrons to make it stable or happy

O had a negative ionic charge bc it wants to gain electrons to make it stable or happy

therefore,

QA) O would not want/wouldn't use up the energy to transfer 6 of its electrons and Mg would accept O's electrons
Q3) goes against laws of chemistry
Q4) Mg can not gain 2 extra electrons unless it is a double molecule (which it is not) a

Give the chemical symbol of an element in the third period (row) of the periodic table with four 3p electrons.

Ann [662]

<u>Answer: </u>The chemical symbol of the element is Sulfur.

<u>Explanation:</u>

The element which is present in third period of the periodic table having four 3p electrons is Sulfur. Sulfur is the 16th element of the periodic table which has 6 valance electrons.

The electronic configuration of this element is: $[Ne]3s^23p^4$

This element is considered as a non-metal because it will accept electrons in order to attain stable electronic configuration.

Hence, the chemical symbol of the element is Sulfur.
