What are the 3 main subatomic particles?

The three subatomic particles are protons, neutrons, and electrons.

What is in the nucleus of an atom?

The nucleus contains protons and neutrons.

How does the diameter of the nucleus compare to the diameter of the atom?

The larger the diameter of the nucleus, the larger the atom in both diameter and mass.

What are protons? What is their charge? Where art they located?

Protons are subatomic particle of the nucleus and are positively charged.

What are neutrons? What is their charge? Where are they located?

Neutrons are a subatomic particle of the nucleus and have no charge, neutral.

What are electrons? What is their charge? Where are they located.

Electrons are subatomic particles that are found in the energy levels swirling around the nucleus on an electron cloud and are negatively charged.<...

How does the mass of an electron compare to protons and neutrons?

The mass of an electron is about 1,830 times smaller than protons and neutrons, so it has very little mass.

An atom is neutral if the number if protons and electrons are? Why?

They are neutral because the same amount of positively charged protons cancels out the same amount of negatively charged electrons, making the atom have no charge.

What is an ion?

A positive ion?

A negative ion?

An ion is any atom that has a charge, usually due to exchange of electrons during bonding.

A positive ion is an atom that has one or more protons than electrons.

A negative ion is any atom that has one or more electrons than protons.

How many subatomic particles are in the simplest atom?
What element is the simplest atom?

The simplest atom has 1 proton and 1 electron.

It is hydrogen.

What is the atomic number of an element?

The atomic number tells how many protons are in the element.

What is the atomic number of carbon? Iron?

The atomic number of carbon is 6.
The atomic number of iron is 26.

what is the mass number?

Why aren't electrons included in the mass number?

An isotope is an atom that has the combination of the mass of the protons and neutrons.

Electrons are not included because their mass are so minute that is doesn't change the total mass much, therefore they leave it out.

The mass number of sodium is

23. How many protons and neutrons does it have?

Sodium has 11 protons as the atomic number tells you that. To find the neutrons, subtract the atomic number from the atomic mass, 23-11 equals 12. Therefore there are 12 neutrons.
