Determine whether each of the following statements is true or false. c. The number of electrons in an atom equals the number of neutrons in the atom.

Verified step by step guidance

insert step 1> Identify the components of an atom: protons, neutrons, and electrons.

insert step 2> Recall that in a neutral atom, the number of electrons equals the number of protons.

insert step 3> Understand that the number of neutrons can vary, leading to different isotopes of the same element.

insert step 4> Compare the number of electrons and neutrons in an atom.

insert step 5> Conclude whether the statement 'The number of electrons in an atom equals the number of neutrons in the atom' is generally true or false based on the above understanding.

Key Concepts

Here are the essential concepts you must grasp in order to answer the question correctly.

Atomic Structure

Atoms are composed of three primary subatomic particles: protons, neutrons, and electrons. Protons and neutrons reside in the nucleus, while electrons orbit around the nucleus. The number of protons defines the element, while the number of electrons typically equals the number of protons in a neutral atom, leading to overall charge neutrality.

Neutrons and Electrons

Neutrons are neutral particles found in the nucleus of an atom, while electrons are negatively charged particles that orbit the nucleus. The number of neutrons can vary in atoms of the same element, resulting in different isotopes, whereas the number of electrons in a neutral atom is equal to the number of protons, not neutrons.

True/False Statements in Chemistry

In chemistry, evaluating statements as true or false often requires understanding the relationships between atomic particles. A statement claiming that the number of electrons equals the number of neutrons is generally false for most elements, as the number of neutrons can differ significantly from the number of electrons, especially in isotopes.
