What is an atom?

An atom is the smallest unit of matter that retains the properties of an element. It consists of a dense nucleus containing positively charged protons and uncharged neutrons, surrounded by a cloud of negatively charged electrons that orbit the nucleus in energy levels. Atoms combine to form molecules, which make up all substances in the universe.

What are the three subatomic particles that make up an atom?

The three subatomic particles that make up an atom are protons, neutrons, and electrons. Protons have a positive charge, neutrons have no charge, and electrons have a negative charge. Protons and neutrons are located in the nucleus of an atom, while electrons orbit around the nucleus in electron clouds.

What is the charge of a proton?

The charge of a proton is +1 elementary charge, which is equivalent to approximately 1.602 x 10^-19 coulombs.

What is the charge of an electron?

The charge of an electron is -1 elementary charge, which is approximately -1.602 x 10^-19 coulombs.

What is the charge of a neutron?

A neutron has no charge; it is electrically neutral.

Where are protons and neutrons located within an atom?

Protons and neutrons are located within the nucleus of an atom.

Where are electrons located within an atom?

Electrons are located outside the nucleus of an atom, in specific energy levels or orbits. These energy levels are known as electron shells, with each shell capable of holding a specific maximum number of electrons. The outermost shell, known as the valence shell, determines the atom's chemical properties and interactions with other atoms.

What is the atomic number of an element?

The atomic number of an element is the number of protons found in the nucleus of an atom of that element. It is a unique identifier for each element on the periodic table and determines the position of the element in the periodic table.

What is the mass number of an element?

The mass number of an element is the total number of protons and neutrons in the nucleus of an atom of that element. It is used to identify different isotopes of an element, as isotopes of the same element have the same number of protons but different numbers of neutrons, resulting in different mass numbers.

How does the number of protons determine the identity of an element?

The number of protons in an atom determines the element's identity because each element has a unique atomic number, which is equal to the number of protons in its nucleus. This number defines the chemical properties of the element, as it dictates the element's place on the periodic table and its interactions with other elements. In essence, the number of protons in an atom is what distinguishes one element from another.
