Answer:
D equal numbers of protons and electrons
Step-by-step explanation:
An atom of an element will always contain equal number of protons and electrons.
Atoms are electrically neutral because the number of positive charges and negative charges within them are always equal.
- An atom is the smallest indivisible particles of an element that takes part in a chemical reaction.
- The positively charged particles within an atom are the protons.
- The negatively charged particles within an atom are the electrons.
For;
So number of protons = number of electrons within an atom.
