Describe atomic composition - Middle School Physical Science

The atomic number of an atom is equal to the number of protons in an atom. If the number of protons changes, it is a different element and therefore has a different atomic number.

The answer is positive.

Protons have a positive charge.

Neutrons have a neutral charge.

Electrons have a negative charge.

The answer is neutral.

Protons have a positive charge.

Neutrons have a neutral charge.

Electrons have a negative charge.

The answer is negative.

Protons have a positive charge.

Neutrons have a neutral charge.

Electrons have a negative charge.

Atoms are defined as the smallest unit of matter. They make up everything that takes up space, whether it is living or nonliving. A molecule is more than one atom combined, and therefore is not the same as a single atom. Energy is not made of atoms because it does not take up space.

Atoms are made of smaller particles called protons, neutrons, and electrons. Protons and neutrons exist in the atom's nucleus, while electrons exist in the electron cloud. The answer is not cells because cells are a building block of organisms and are made of atoms.

Electrons are the smallest. An atom is made of smaller particles called protons, neutrons and electrons. Protons and Neutrons are roughly the same size and have a mass of one amu (atomic mass unit). Electrons are much smaller and have a mass of 0 amu.

The overall charge of the atom is neutral. The atom has two positively charged protons and two negatively charged electrons which result in a net charge of zero. The neutron does not have a charge.

Atoms are the smallest. Molecules are two or more atoms. Elements are many of the same type of atom. Cells are often referred to as "the smallest unit of life" because all living things are made of cells. However, cells are made of smaller particles like atoms and molecules as well.
