Anonmetal:
is more likely than a metal to attract an electron
is more likely than a metal to lose an electron
requires more energy than a metal to lose an electron
requires less energy than a metal to lose an electron

A non-metal is more likely than a metal to attract an electron and it requires more energy than a metal to lose an electron.

Explanation: There are 3 types of elements in a periodic table:

1) Metals: These elements easily loose electrons and forms cations. They require less energy to loose electrons because electrons are loosely bound to the nucleus.

2) Non-metals: These elements easily gain electrons to form an anion. They require more energy to loose electrons because the electrons are tightly bound to the nucleus.

3) Metalloids: These elements show both the property of metals and non-metals.

From the given information above, we conclude that a non-metal is more likely than a metal to attract an electron and it requires more energy than a metal to lose an electron.
