Question

how many electrons do na+ has in its outermost shell

Answer 1

na+ have 8 electrons in its outermost shell

Na has 1 electron in its outermost shell it lost 1 electron to become Na+
hope it helped!!

Answer 2

There are eight electrons in the outermost or valence shell of Na+.

• The sodium atom and the Na+ ion have quite different properties.
• Because of its eight electrons in the valence shell, Na+ has no additional properties except its positive charge, which makes it stable and inert.
• An atom of sodium would lose its lone valence shell electron.
• A single valence electron makes the Na atom and other groups of alkali metal atoms chemically reactive.
• Alkali metals are a group of elements with a tendency to lose an electron in their outermost shell and adopt a noble gas electron configuration.
