Answer : The element will be Boron which has 5 electrons in it, and at the atomic nucleus it consists of 5 neutrons and 5 protons.
The lewis electron dot structure for boron will have three dots on the atom.
Which can be represented as · X :
Where X represents the element and dots represents the electrons present in the outermost valence shell.
Boron distributes its 5 electrons in this way, that first shell has 2 electrons and the second shell has 3 electrons.
