SubatomicEParticles - CORRECT ANSWER -The neutrons, protons, and electrons in an atom.
Cathode Rays - CORRECT ANSWER -
Streams of electrons emitted by the cathode in a partially evacuated tube.
Electron - CORRECT ANSWER -A subatomic particle that has a relative charge of 1-
and essentially zero mass. The first subatomic particle to be discovered and was discovered by J.
J. Thomson.
Ion - CORRECT ANSWER -An atom or molecule that has a positive or negative charge.
Cation - CORRECT ANSWER -A positively charged ion.
Anion - CORRECT ANSWER -A negatively charged ion.
Radioactivity - CORRECT ANSWER -The spontaneous emission of high-
energy radiation and particles by materials.
Beta (B) Particle - CORRECT ANSWER -A radioactive emission that is a high-energy electron.
Alpha (a) Particle -ECORRECT ANSWER -
A radioactive emission with a charge of 2+ and a mass equivalent to that of a helium nucleus.
Nucleus (of an atom) - CORRECT ANSWERE-
The positively charged center of an atom that contains nearly all the atom's mass.
,Proton - CORRECT ANSWER -
A subatomic particle, present in the nucleus of an atom, that has a relative charge of 1+ and a ma
ss number of 1.
Neutron - CORRECT ANSWER -
An electrically neutral (uncharged) subatomic particle with a mass number of 1.
Atomic Mass Unit (amu) - CORRECT ANSWER -
Unit used to express the relative masses of atoms and subatomic particles that is exactly 1/12 th
e mass of one atom of carbon with 6 protons and 6 neutrons in its nucleus.
Dalton (Da) - CORRECT ANSWER -A unit of mass equal to 1 atomic mass unit.
Isotopes - CORRECT ANSWER -
Atoms of an element containing the same number of protons but different numbers of neutrons.
Atoms with identical atomic numbers but different mass numbers.
Nuclide - CORRECT ANSWER -AEspecific isotope of an element.
Atomic Number (Z) - CORRECT ANSWER -The number of protons in the nucleus of an atom.
Nucleon - CORRECT ANSWER -A proton or neutron in a nucleus.
Mass Number (A) - CORRECT ANSWER -
The number of nucleons in an atom (protons and neutrons).
Periodic Table of the Elements - CORRECT ANSWER -
A chart of the elements in order of their atomic numbers and in a pattern based on their physical
and chemical properties.
, Period (of elements) - CORRECT ANSWER -All the elements in a row of the periodic table.
Group or Family (of elements) - CORRECT ANSWER -
All the elements in a column of the periodic table.
Radionuclide - CORRECT ANSWER -A radioactive (unstable) nuclide.
Halogen - CORRECT ANSWER -An element in group 17 of the periodic table.
Alkali Metal - CORRECT ANSWER -An element in group 1 of the periodic table.
Alkaline Earth Metal - CORRECT ANSWER -An element in group 2 of the periodic table.
Metals - CORRECT ANSWER -
Elements that are typically shiny, malleable, ductile solids that conduct heat and electricity well a
nd tend to form positive ions.
Nonmetals - CORRECT ANSWER -
Elements with properties opposite those of metals, including poor conductivity of heat and elect
ricity.
Metalloids or Semimetals - CORRECT ANSWER -
Elements that tend to have the physical properties of metals and chemical properties of nonmet
als.
Main Group Elements or Representative Elements - CORRECT ANSWER -
The elements in groups 1,2,and 13 through 18 of the periodic table.
