# data[].attributes.body
- valence shells is the outer ring
- pronton, neutron, electron
- smallest thing
- has lots of energy

# data[].attributes.body
has a nucleus consisting of protons and neutrons and outer electron shells

# data[].attributes.body
electrons are placed in valence shells which dictate the properties and reactivity of the atom

# data[].attributes.body
The mass of an atom comes from the protons and neutrons in the nucleus.

# data[].attributes.body
Atoms consist of neutrons, protons and electrons. They are surrounded by rings of electrons which varies with the amount of electrons in each ring. It is the smallest unit of matter.
The valence shell is the outer ring, and based on the number of electrons it can fit, it wants to "complete" that ring by interacting with other atoms.

3 parts of an atom: electrons, protons, neturons, they are mostly empty space. Electrical attraction hold protons and electrons

# data[].attributes.body
The atom's mass is mostly from the nucleus and there is a lot of space between the nucleus and electrons. The nucleus is made up of protons and neutrons. There are electron shells that can hold a certain number of electrons. Electrons want to complete this shell.

# data[].attributes.body
The atom has a nucleus made up of neutrons and protons, as well as an electron field where the electrons orbit the atom

# data[].attributes.body
-Has electrons, neutrons and protons

-There are different electron shells

-Electrons are the smallest and have the least mass

-Protons are made up of three quarks

# data[].attributes.body
Atoms contain a nucleus (containing protons and neutrons) and an electron shell on the outside. Most of the atoms mass comes from the nucleus.

# data[].attributes.body
- Atoms are comprised of subatomic particles: protons, neutrons, and electrons
- While most of an atom's mass comes from the nucleus, most of its volume comes from the electron field

# data[].attributes.body
There are three basic subatomic components: neutrons, protons, and electrons. Neutrons have a neutral charge, while protons and electrons have a positive and negative charge respectively. Most of the mass of an atom is concentrated in the nucleus, occupying very little space, while the volume in which the electrons occupy is significantly larger. Electrons for the most part do not have any mass and occupy shells in the athom.

-They are building blocks of the universe.
-They are made up of protons, neutrons, and electrons.
-They are also made up of quarks.
