|---|---|---|---|---|---|
| atomic radius | show 🗑
|
||||
| show | In chemistry, a group is a column of elements in the periodic table of the chemical elements. There are 18 numbered groups in the periodic table; the f-block columns are not numbered.
🗑
|

| EM spectrum | show 🗑
|
||||
| show | Electronegativity, symbolized as χ, is the tendency for an atom of a given chemical element to attract shared electrons when forming a chemical bond
🗑
|

| frequency | show 🗑
|
||||
| show | Ionic radius, , is the radius of a monatomic ion in an ionic crystal structure.
🗑
|
||||
| ionization energy | show 🗑
|
||||
| isotopes | show 🗑
|
||||
| show | The Planck constant, or Planck's constant, is a fundamental physical constant denoted h, and is of fundamental importance in quantum mechanics.
🗑
|
||||
| show | In chemistry and physics, a valence electron is an electron in the outer shell associated with an atom, and that can participate in the formation of a chemical bond if the outer shell is not closed
🗑
|
||||
| show | the wavelength is the spatial period of a periodic wave—the distance over which the wave's shape repeats
🗑
|
||||
| alkali metals | show 🗑
|
||||
| alkaline earth metals | show 🗑
|
||||
| show | An atom is the smallest unit of ordinary matter that forms a chemical element.
🗑
|
||||
| atomic # | show 🗑
|
||||
| avg. atomic mass | show 🗑
|
||||
| electrons | show 🗑
|
||||
| show | The electron affinity of an atom or molecule is defined as the amount of energy released when an electron is attached to a neutral atom or molecule in the gaseous state to form a negative ion.
🗑
|
||||
| show | The halogens are a group in the periodic table consisting of five or six chemically related elements: fluorine, chlorine, bromine, iodine (I), and astatine.
🗑
|
||||
| show | The mass number, also called atomic mass number or nucleon number, is the total number of protons and neutrons in an atomic nucleus
🗑
|
||||
| show | The neutron is a subatomic particle, symbol n or n⁰ , which has a neutral charge, and a mass slightly greater than that of a proton.
🗑
|
||||
| show | The noble gases make up a class of chemical elements with similar properties; under standard conditions, they are all odorless, colorless, monatomic gases with very low chemical reactivity.
🗑
|
||||
| nucleus | show 🗑
|
||||
| show | The oxidation state, sometimes referred to as oxidation number, describes the degree of oxidation of an atom in a chemical compound.
🗑
|
||||
| show | The photon is a type of elementary particle. It is the quantum of the electromagnetic field including electromagnetic radiation such as light and radio waves, and the force carrier for the electromagnetic force.
🗑
|
||||
| proton | show 🗑
|
||||
| show | The speed of light in vacuum, commonly denoted c, is a universal physical constant important in many areas of physics. Its exact value is defined as 299792458 metres per second.
🗑
|
||||
| transition metals | show 🗑

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.
