Question

what is an element that has more valence electrons than fluorine and less energy levels than sodium?

Answer 1

From the periodic chart the only element between F and Na is Neon. Neon has one more valence electron 8 than fluorine 7, and is one energy level shy of Na.

Answer 2

An element that has more valence electrons than fluorine and less energy levels than sodium is Neon.

What are valence electrons?

Those electrons which are present on the outermost shell of any atom will known as valence shell electrons.

• Atomic number of fluorine is 9 and Neon is 10, so Neon will have one more valence electron than the fluorine atom.
• Atomic number of sodium is 11 & it is present in the 3rd period of the periodic table and will have one more shell in it.

Hence required element is neon.
