An atom contains three kinds of particles:

protons, neutrons, and electrons.

Where is the energy in an atom?

in the nucleus because energy is needed to hold the nucleus together

Electrons are

negatively charged.

the nuclei of atoms to split apart is called

nuclear fission

Electrons, which have a negative charge, are in constant motion around the

nucleus

This center is called the atom's

nucleus.

Electrons are found where?

outside the nucleus orbiting in an electron cloud.

Electrons are very small how big?

(.0018amu) and move extremely fast .

Both protons and neutrons are

1amu.

the nucleus

Positive protons and neutral neutrons are found in

the nucleus

The center of an atom is

What is the structure of the nucleus?

The nucleus is composed of positive protons and neutral neutrons tightly packed together.

How are the parts of the nucleus held together?

The parts of the nucleus are held together by the stronger nuclear force, which can keep positive protons from repelling each other in the presence of the nucleus.

nuclear fusion

a nuclear reaction in which nuclei combine (to produce more massive nuclei) which results in the release of large amounts of energy

protons

a subatomic particle with a positive charge that is located in the nucleus of an atom

neutron

a subatomic particle with no electric charge, located within the nucleus of the atom

A nuclear power plant produces energy by

causing the nuclei of atoms to split apart.

Protons,which are positively charged, and neutrons ,which have no charge, are found in the

center of an atom

What holds the nucleus together ?

energy ( strong nuclear force).

nuclear

energy the energy released when the nucleus of an atom is split apart (during fission) or combined with another nucleus (during fusion)

The nucleus of an atom contains protons and neutrons and DNA. true are false?

false doesn't contain DNA

An atom is hold together by

the attraction between the positive protons and the negative electrons

nucleus,

the center of an atom containing protons and neutrons (related term: nuclei, nuclear); a region in a cell that is surrounded by a membrane and contains genetic material

strong nuclear force

the force that holds the nucleus together. The neutrons help so the positive force of the protons don't break up the nucleus.

Nuclear fusion occurs when

the nuclei of atoms join together

nuclear fission

the nucleus of an atom is spit and releases energy

Electrons are far away far away from the nucleus True are false ?

true .

Electrons are very small and very far from the nucleus, they move very fast which forms what ?

which form an electron cloud.
