Answer 2

All atoms of the same element have the same number of protons

Step-by-step explanation:

• Atoms are the smallest particles of elements that can take part in a chemical reaction.
• Atoms of an element have the same number of protons but may have a different number of electrons or neutrons.
• Atoms of the same element with different neutrons are called isotopes.
• An element may have two or more isotopes. For example, oxygen isotopes; oxygen-16, oxygen-17 and oxygen-18.
• Atoms may have a different number of electrons when they lose or gain an electron(s) to attain a stable configuration.
