an element has six valence electrons which ionic charge will its ion carry

Question

2+
6+
6-
2-

Answer 1

An element with six valence electrons is typically from Group 16 of the periodic table (such as oxygen or sulfur). When forming an ion, such an element usually gains two electrons to achieve a stable electron configuration (similar to that of the nearest noble gas).

Therefore, the ionic charge for this element when it forms an ion would be 2-.
