Question

Which is NOT true about the structure of the atom?

O Protons are the positively charged particles in the nucleus.
O A nucleus accounts for most of the mass of the atom and occupies a large fraction of its volume.
O Neutrons are electrically neutral and have a mass slightly greater than that of a proton.
O Atoms contain the same number of protons and electrons.

Answer 1

Answer: "Atoms contain the same number of protons and electrons" is NOT true

Step-by-step explanation:

While an element can contain the same number of protons and electrons, this is often not the case. Many elements tend to exist in a charged states (as cations or anions) in which they do not have the same number of protons and electrons.
