Covalent bonds
An element.
mass number = protons + nuetrons
The chemical properties of an element are determined by the number of electrons, which is determined by the number of protons. Isotopes vary in the number of neutrons in an atom of the same element (same number of protons). Since neutrons do not influence the number of protons or electrons, they do not affect chemical properties.
The atomic number and number of protons are always the same in a normal element.
The elements of a compound are the simplest components that it can be broken down into by chemical means. The atoms of an element have the same number of protons and electrons and have the same behaviors.
The mass number of an atom is defined as the total number of protons and neutron (collectively called "nucleons") in the atomic nucleus. For example, a helium atom with 2 protons and 2 neutrons would have a mass number of 4.
positive charges
The number of protons of a chemical element is equal with atomic number.
Ions. An ion is an atom in which the number of electrons do not equal the number of protons.
Elements are pure substances inwhich all the atoms have the same number of protons (same atomic number) and thus have the same chemical properties. They cannot be separated by normal chemical means into any simpler substances.
These substances are called ions.

The number of protons is depending on to atomic number of a chemical element. Each chemical element has a specific number of protons.
The number of protons is equal to the atomic number of a chemical element.
The number of protons is equal to the atomic number of a chemical element. In a neutral atom number of protons=number of electrons.
The number of protons is equal to the atomic number of a chemical element. In a neutral atom number of protons=number of electrons.
