What is an atom?

An atom is the smallest unit of matter that retains the properties of an element. It consists of a nucleus containing protons and neutrons, surrounded by electrons orbiting the nucleus. Atoms combine to form molecules, which are the building blocks of 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 (they are neutral), and electrons have a negative charge. Protons and neutrons are found in the nucleus of the atom, while electrons orbit around the nucleus.

What is the charge of a proton?

The charge of a proton is positive, specifically +1.6 x 10^-19 coulombs.

What is the charge of an electron?

The charge of an electron is -1.6 x 10^-19 coulombs.

Where are protons and neutrons located in an atom?

Protons and neutrons are located in the nucleus of an atom, which is at the center of the atom. The nucleus houses the majority of the atom's mass, with protons carrying a positive charge and neutrons being neutral in charge. Electrons are found in the electron cloud surrounding the nucleus.

Where are electrons located in an atom?

Electrons are located in the electron cloud surrounding the nucleus of an atom. The electrons move around the nucleus in specific energy levels or shells, and their exact location within these energy levels is best described by the concept of probability density, rather than a fixed position.

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 uniquely identifies each element on the periodic table and determines the element's chemical properties.

What is the mass number (atomic mass) of an element?

The mass number, or atomic mass, of an element is the total number of protons and neutrons in the nucleus of an atom of that element. It is typically denoted by the symbol "A" and is used to identify different isotopes of an element.

What is an isotope?

An isotope is a variant of a chemical element that has the same number of protons in its nucleus as other atoms of the same element but a different number of neutrons. This results in variations in atomic weight for the element. Isotopes of an element behave similarly in chemical reactions but may have different physical properties due to their differing atomic weights.

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

To calculate the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass. The atomic number represents the number of protons in the nucleus, while the atomic mass represents the sum of protons and neutrons in an atom. By subtracting the atomic number from the atomic mass, you can determine the number of neutrons present in the atom.
