Question

Magnesium (Mg) has two electrons in its outer shell. Mg will _____.

try to share electrons with another atom
try to gain six electrons from another atom
try to give two electrons to another atom



and question two is

When an atom loses electrons it becomes _____.


positively charged because its protons outnumber its electrons
negatively charged because its electrons outnumber its protons
positively charged because its electrons outnumber its protons

Answer 1

1.Magnesium (Mg) has two electrons in its outer shell. Mg will try to give two electrons to another atom (because the Mg is metal).

2. When an atom loses electrons, it becomes positively charged because its protons outnumber its electrons. ( In an atom, number of protons = number of electrons, when electrons are lost, the number of protons >the number of electrons.)
