color coded periodic table with ion charges

A Yttrium is in group 3, and elements in this group are metals that tend to lose electrons.

B The nearest noble gas is krypton, so we predict that selenium will gain two electrons to form the Se 2 − ion, which has the same number of electrons as krypton.

A Selenium is a nonmetal in group 16, so it will tend to gain electrons.

Aluminum will lose three electrons to form the Al 3 + ion, which has the same number of electrons as neon. B The nearest noble gas to aluminum is neon.

A Aluminum is a metal in group 13 consequently, it will tend to lose electrons.

After locating the noble gas that is closest to the element, determine the number of electrons the element must gain or lose to have the same number of electrons as the nearest noble gas.

Based on its location in the periodic table, decide whether the element is a metal, which tends to lose electrons a nonmetal, which tends to gain electrons or a semimetal, which can do either.

Identify the group in the periodic table to which the element belongs.
