Describe the different particles that make up an atom.

What are some examples of elements? How do you know they are elements?

How can you use the Periodic Table of Elements to help you find information about specific elements?

How did scientists conclude that most of an atom is empty space?

What are some different careers available for people that want to study atoms and molecules?

1.Electrons are found in shells or orbitals that surround the nucleus of an atom. Protons and neutrons are found in the nucleus. They group together in the center of the atom. That's all you have to remember.

2. Periodic table. a table of the chemical elements arranged in order of atomic number. Chemical Group/Family. In chemistry, a group (also known as a family) is a column of elements in the periodic table of the chemical elements.

3. If you were to look at some iron filings with a Scanning Tunneling Microscope, you would be able to see tiny spheres of iron atoms. Microscopic Atoms Atoms are extremely small. ... If you were to look at some iron filings with a Scanning Tunneling Microscope, you would be able to see tiny spheres of iron atoms.

4.The three main subatomic particles that form an atom are protons, neutrons, and electrons. The center of the atom is called the nucleus. First, let's learn a bit about protons and neutrons, and then we will talk about electrons a little later. Protons and neutrons make up the nucleus of an atom.

5. An element (also called a "chemical element") is a substance made up entirely of atoms having the same atomic number; that is, all of the atoms have the same number of protons. Hydrogen, helium, oxygen, nitrogen, carbon, gold, silver, lead, and uranium are well-known examples of elements

6.The periodic table of elements arranges all of the known chemical elements in an informative array. Elements are arranged from left to right and top to bottom in order of increasing atomic number. Order generally coincides with increasing atomic mass. The rows are called periods.

7.In 1911, a British scientist named Ernest Rutherford discovered that an atom is mostly empty space. He concluded that the positively charged particles are contained in a small central core called the nucleus. ... This attraction holds the negatively charged particles in the atom.
