|---|---|---|---|---|---|
| The smallest particle of an element that can be identified with that element. Consists of protons and neutrons in a nucleus surrounded by electrons. | Atom
🗑
|
||||
| A substance made of only one kind of atom. Example of elements are carbon, hydrogen, oxygen, and nitrogen. | Element
🗑
|
||||
| The perpetual random movement of microscopic particles suspended in a fluid medium. | Brownian motion
🗑
|
||||
| The smallest particle of substance consisting of two or more atoms of the same or different elements bonded together. | Molecule
🗑
|
||||
| A chemical substance made of atoms of two or more different elements combined in a fixed propotion. | Compound
🗑
|
||||
| A description that uses numbers and symbols of elements to describe the proportions of elements in a compound or reaction. | Chemical formula
🗑
|
||||
| The possitively charged center of an atom, which contains protons and neutrons and has almost all the mass of the entire atom but only a tiny fraction of the volume. | Nucleus
🗑
|
||||
| The principal building block of the nucleus; a neutron or a proton. | Nucleon
🗑
|
||||
| An electrically neutral particle that is one of the two kinds of particles found in the nucleus of an atom. | Neutron
🗑
|
||||
| A possitvely charged particle that is one of the two kinds of particles found in the nucleus of an atom. | Proton
🗑
|
||||
| A form of a element having a particular number of neutrons in the nuclei of its atoms. Different isotopes of a particular element have the same atomic number but different atomic mass numbers. | Isotope
🗑
|
||||
| Number of protons in the nucleus of an atom. | Atomic number
🗑
|
||||
| An atom (or group of atoms bound together) with a net electric charge, which is due to the loss or gain of electrons. | Ion
🗑
|
||||
| A model in which the electrons of an atom are pictured as grouped in concentric shells around the nucleus. | Shell model of the atom
🗑
|
||||
| A chart that lists elements by atomic number and by electron arrangements, so that elements with similar chemical properties are in the same column. | Periodic table
🗑
|
||||
| A fourth phase of matter, in addition to solid, liquid, and gas. In the plasma phase, which exists mainly at high temperature, matter consits of positively charged ions and free electrons. | Plasma
