section 1  Composition of Matter

# data[].attributes.body
A molecule is an electrically neutral group of two or more atoms held together by chemical bonds.

# data[].attributes.body
each of the actual or potential patterns of electron density that may be formed in an atom or molecule

# data[].attributes.body
A chemical compound is a chemical substance composed of many identical molecules composed of atoms from more than one element held together by chemical bonds.

# data[].attributes.body
A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds.

# data[].attributes.body
A covalent bond, also called a molecular bond, is a chemical bond that involves the sharing of electron pairs between atoms.

# data[].attributes.body
Isotopes are variants of a particular chemical element which differ in neutron number, and consequently in nucleon number.

# data[].attributes.body
The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge and a mass slightly greater than that of a proton.

# data[].attributes.body
The atomic number or proton number of a chemical element is the number of protons found in the nucleus of every atom of that element.

# data[].attributes.body
The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons

# data[].attributes.body
The electron is a subatomic particle, symbol e⁻ or β⁻ , whose electric charge is negative one elementary charge.

# data[].attributes.body
An atom is the smallest unit of ordinary matter that forms a chemical element. Every solid, liquid, gas, and plasma is composed of neutral or ionized atoms.

# data[].attributes.body
A proton is a subatomic particle, symbol p or p⁺ , with a positive electric charge of +1e elementary charge and a mass slightly less than that of a neutron.

# data[].attributes.body
In chemistry, an element is a pure substance which cannot be broken down by chemical means

# data[].attributes.body
the positively charged central core of an atom, consisting of protons and neutrons and containing nearly all its mass

# data[].attributes.body
In classical physics and general chemistry, matter is any substance that has mass and takes up space by having volume.

# data[].attributes.body
Mass is both a property of a physical body and a measure of its resistance to acceleration when a net force is applied.
