Elements of Life Key Definitions (1)

(01 - 07)

HideShow resource information
Atomic Number
“Total protons in the nucleus”
1 of 12
Mass Number
“Total neutrons + protons in the nucleus”
2 of 12
Isotope
“Atoms of the same element with different mass numbers”
3 of 12
Relative Atomic Mass
“Mass of a single atom scaled to 12C exactly”
4 of 12
Relative Molecular Mass
“Mass of a single molecule scaled to 12C exactly”
5 of 12
Cation
“Atom or molecule that has lost an electron"
6 of 12
Anion
“Atom or molecule that has gained and electron"
7 of 12
Fusion Reactions
2 nuclei joining / fusing together to make a single heavier nucleus. Require incredibly high temperature and pressure.
8 of 12
Fission Reactions
Involve a nucleus breaking apart to form 2 smaller nuclei. Usually involve atoms with large nuclei such as the Lanthanides and Actinides. They can produce a, B and y emissions.
9 of 12
Electronegativity
“The ability of an atom to draw electrons to itself”
10 of 12
ion
“An atom or a molecule that has gained or lost 1 or more electrons"
11 of 12
ionic bonding
“Cations and anions held together by an electrostatic bond because of their opposite charges”
