an element has six valence electrons. which ionic charge will its ion carry? (1 point) 2+ 6+ 6- 2-
Answer
Explanation:
Step1: Recall octet - rule and ion - formation
Elements tend to gain, lose, or share electrons to achieve a stable octet (8 - electron) configuration in their outer shell. An element with 6 valence electrons will gain 2 electrons to reach 8 valence electrons.
Step2: Determine the charge of the ion
When an element gains electrons, it forms a negatively - charged ion (anion). Since it gains 2 electrons, the charge of the ion is 2-.
Answer:
2 -
