Question

Name the element which has one electron in the outermost shell​

Answer 1

Lithium (Li), sodium (Na), and potassium (K) have a single electron in their outermost shells

Answer 2

The elements that have one electron in the outermost shell are Sodium, Lithium, and Hydrogen.

Explanation:

• These elements are known to be unstable elements due to 1 electron in the outermost shell. But, it can gain stability by gaining or losing the electrons.
• After losing the electrons, they become positively charged and after gaining electrons, they become negatively charged.
• The electrons in the outermost shell will say about the reactivity or tendency of that particular atom to form a bond with the other atom.
• And also, these elements won't achieve the octet rule, which is only applicable for the elements which have 8 electrons in the outer shell.
