Match the following

• I ask

• If I have questions

• Isotope

• Atoms of the same element with a different mass

• Ion

• Atoms of the Same Element with a different charge

The mass of Atoms of the same element will always be the same

• True

• False

Answer explanation

False! Isotopes of the same element have different numbers of Neutrons which gives them a different mass.

PS1.A:

The Number of Protons and Electrons will always be the same as the atomic number in a Neutral atom

• True

• False

Answer explanation

TRUE! In a neutral atom (an atom with no charge) the positive protons and negative electrons must be balanced, meaning the number of electrons is the same as the atomic number which represented the number of protons.
