Atoms Faq

Atoms are the basic building blocks of matter and consist of protons, neutrons, and electrons. Protons and neutrons are found in the nucleus at the center of the atom, while electrons orbit around the nucleus. Elements are made of one or more atoms that all have the same number of protons. Atoms are over 99% empty space, but electrons produce energy fields that cause matter to take up space and prevent objects from passing through each other. Quarks make up protons and neutrons and are the most fundamental particles, while the strong force holds atomic nuclei together.

Atoms - FAQ

What are atoms?


Atoms make up matter. They have neutrons, protons and electrons.
What are neutrons, protons and electrons?
Neutrons are tiny particles that are neutrally charged and are found in the
nucleus of the atom. Protons are positively charged and are also found in
the nucleus. Electrons are negatively charged and are always zooming
around the nucleus.
What is an element?
An element can be one or more atoms that all have the same number of
protons. The number of protons is the atomic number.
1

Ex. Hydrogen has one proton and no neutrons. Its atomic


weight is 1.0079.

Hydroge
n
1.0079

Are atoms mainly empty space?


Atoms are 99.9% empty space. There is empty space because the electrons
are zooming around in a space very huge compared to the size of the
nucleus. However, this empty space constantly has energy fluctuations in it,
so it may or may not be called empty space.
If atoms are mostly empty, why cant I put my hand through a table?
It is because the electrons produce energy fields that repel each other.
Are there any particles smaller than protons or neutrons?
Quarks make up protons and neutrons. They are the most fundamental
building blocks of matter. No one has ever seen quarks, but scientists know
they exist.
What is matter?
Matter is anything that takes up space and has mass.

What holds atoms together?


The electrons are attracted to the nucleus because they want to bond with
the positively charged protons. The electrons are negatively charged.
Positive and negative charges attract to each other.
What hold the nucleus together if the protons want to repel?
The strong force holds the protons together. If it was to suddenly disappear,
we and everything else would fly apart in invisible particles.
Can you split atoms?
Yes, but you need specialized equipment and intense heat and pressure. It
also creates a huge explosion because of the splitting of the nucleus.
