|---|---|---|---|---|---|
| ATOM | The smallest part of an element that still has the chemical properties of that element. Atoms are made up of even smaller particles such as protons, neutrons, and electrons.
🗑
|
||||
| PROTON | A particle in the nucleus of an atom that has a positive charge. The number of protons in the nucleus determines the element the atom forms and its atomic number.
🗑
|
||||
| ELECTRON | A tiny particle, much smaller than an atom, that is charged with a small amount of negative electricity. All atoms have electrons surrounding the nucleus at different distances.
🗑
|
||||
| NEUTRON | A subatomic particle with no electrical charge found in the nucleus of all atoms except hydrogen. A neutron has a mass slightly greater than that of a proton.
🗑
|
||||
| NUCLEUS OF AN ATOM | The central area of the atom. It is composed of two kinds of subatomic particles, protons and neutrons.
🗑
|
||||
| VALENCE ELECTRON | an electron of an atom, located in the outermost shell (valence shell) of the atom, that can be transferred to or shared with another atom.
🗑
|
||||
| ELECTRON CLOUD | the group of electrons revolving around the nucleus of an atom; a cloudlike group of electrons
🗑
|
||||
| ORBITALS | Atomic orbitals are regions of space around the nucleus of an atom where an electron is likely to be found.
🗑
|
||||
| ENERGY LEVEL | the energy levels of the atoms correspond to the rows of the orbital
🗑
|
||||
| SUBATOMIC PARTICLE | A unit of matter or energy that's the fundamental makeup of all matter. For example protons and neutrons
🗑
|
||||
| ATOMIC MASS | The mass of an atom or a molecule
🗑
|
||||
| ATOMIC NUMBER | The atomic number is equal to the number of protons in an atom's nucleus. The atomic number determines which element an atom is.
🗑

Review the information in the table. When you are ready to quiz yourself you can hide individual columns or the entire table. Then you can click on the empty cells to reveal the answer. Try to recall what will be displayed before clicking the empty cell.
To hide a column, click on the column name.
To hide the entire table, click on the "Hide All" button.
You may also shuffle the rows of the table by clicking on the "Shuffle" button.
Or sort by any of the columns using the down arrow next to any column heading.
If you know all the data on any row, you can temporarily remove it by tapping the trash can to the right of the row.
