Atoms and Isotopes

Front

What are atoms?

Back

Atoms are the basic units of matter, consisting of a nucleus made of protons and neutrons, surrounded by electrons.

Front

What are isotopes?

Back

Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons.

Front

How do you calculate the number of neutrons in an isotope?

Back

To find the number of neutrons, subtract the atomic number (number of protons) from the mass number (total number of protons and neutrons).

Front

What is the mass number of an atom?

Back

The mass number is the total number of protons and neutrons in the nucleus of an atom.

Front

What is the atomic number?

Back

The atomic number is the number of protons in the nucleus of an atom, which determines the element's identity.

Front

What is the difference between protons and neutrons?

Back

Protons are positively charged particles found in the nucleus, while neutrons are neutral particles that also reside in the nucleus.

Front

What is the significance of electrons in an atom?

Back

Electrons are negatively charged particles that orbit the nucleus and are involved in chemical bonding and reactions.

Front

What is Deuterium?

Back

Deuterium is an isotope of hydrogen with one proton and one neutron.

Front

What is the relationship between isotopes and chemical properties?

Back

Isotopes of an element generally have the same chemical properties because they have the same number of electrons.
