A change in the number of neutrons in an atom will change an isotope. What will happen when the number of protons changes in an atom? A. Energy will be destroyed.
B. Chemical bonding will occur.
C. A new element will form.
D. The atom will gain a charge.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
