Question

what does yttrium do to become stable? y will 1 and have a 2 charge. a. lose 2 electrons b. lose 3 electrons c. gain 2 electrons d. gain 3 electrons e. lose 4 electrons f. gain 4 electrons g. +2 h. +3 i. -2 j. -3 k. +4 l. -4

Explanation:

Yttrium (Y) is a metal in group 3 of the periodic table. Metals tend to lose electrons to achieve a stable electron - configuration. Yttrium has 3 valence electrons and will lose 3 electrons to have a stable noble - gas like electron configuration. When it loses 3 electrons, it forms a cation with a + 3 charge.

Answer:

1. B. lose 3 electrons
2. H. +3
