The electrons in an atoms outermost orbitals, the electrons, are represented in a(n) , which consists of the elements symbol, representing the atomic nucleus and inner-level electrons, and the appropriate number of dots.

valence electrons

electron dot structures

Explanation:

Valence electrons -

It refers to the number of electrons that are present on the very last shell of any atom , is referred to as valence electrons .

Valence electrons are responsible to show any chemical properties of the atom .

Hence , the answer of the first part is - valence electrons .

Electron dot structures -

It is the structural representation , where the symbol of the element is placed at the center and the electrons are arranged surrounding it .

Hence , the answer of the second part is - electron dot structures .

with this one i know the answer in craters one reason i looked it up and i learned about it there is my evidence
