Which of the following is correct about an element with an atomic number equals to 11?A) The element has 11 valence electronsB) the element has 11 neutronsC) the element has 11 protons and 11 electronsD) the element has 2 valence electron

Answer 1

ANSWER

The element will have 11 protons and 11 electrons

option C

EXPLANATION

Element can be defined as a substance that cannot be split into two simpler unit by an ordinary chemical reaction.

Recall, that the atomic number is equal to the number of proton

Since the atomic number is 11, then the number of proton is 11

In a neutral atom, the number of proton is equal to the number of electron

Therefore, the element will have 11 protons and 11 electrons

Hence, the correct answer is option C
