Anything that has mass and takes up space.
What is matter?
The basic unit of an element. All matter is made up of atoms.
What is an Atom?
A positively charged subatomic particle located at the center of an atom.
What is a proton?
A subatomic particle with no charge located at the center of an atom.
What is an Neutron?
Protons and neutrons clump together at the center of an atom to form the nucleus of an atom.
What is the Nucleus?
A chart of all known elements that scientists reference when working with atoms or molecules.
What is The Periodic Table?
Two or more atoms bonded together.
What is a molecule?
Examples of matter include any solids, liquids or gases. A ball, water and oxygen are all examples of matter. Examples of things that are NOT matter would be ideas, energy and feelings.
What are examples of matter?
Scientists have invented special microscopes to help us see atoms. Before the microscopes were invented, scientists did experiments to learn about the structure of an atom.
Atoms are tiny, how do we see them?
Atoms are made up of 3 different smaller particles; protons, neutrons and electrons.
What Atoms are from?
Some examples of elements are gold, iron, copper and carbon. Anything on the periodic table is an element. All elements are pure substance made up of only one type of atom.
What is an example or examples of elements?
Scientists in the medical field use molecules on a regular basis to develop new medicines to help fight diseases. Specifically, biomedical scientists may be able to replicate naturally occurring molecules to help people with deficiencies.
What are jobs that people have who study molecules and atoms?
Each element has a certain number of protons, electrons and neutrons. For example, carbon has 6 protons, 6 electrons and 6 neutrons. Oxygen has 8 protons, 8 electrons and 8 neutrons.
What makes elements different from each other?
The Periodic Table of Elements shows the names and abbreviations for each element. It also tells you how many protons, neutrons and electrons each atom has. The atomic number of each element corresponds with how many protons and electrons an element has. We cover more details about the periodic table in our lesson called “The Periodic Table.”
How is the periodic table used?
A subatomic particle of an atom that is negatively charged and orbits the nucleus extremely fast.
What is an Electron?
Atoms are found everywhere. All matter is made up of atoms.
Where are Atoms?
