Question 0

Reducing agent / reductant

Answer 0

Gives up electrons. INCREASES charge

Question 1

Oxidizing agent / oxidant

Answer 1

Takes electron for itself. LOWER charge.

Question 2

Oxidation-reduction / redox reactions

Answer 2

A reaction that has oxidation accompanied by reduction. (See definitions of oxidant and reductant)

Question 3

Displacement Reactions

Answer 3

Redox between metals and acids and metals and salts

Question 4

Paramagnetic

Answer 4

Very weakly attracted by poles of a magnet, electrons not completely spin paired

Question 5

Coulomb’s Law

Answer 5

Everything held together by electrostatic, negative electron attracted to positive nucleus

Question 6

Aufbau Principle

Answer 6

Electrons placed in orbitals, sublevels and levels in order of increasing energy

Question 7

Pauli Exclusion Principle

Answer 7

No two electrons have same quantum numbers

Question 8

Diamagnetic

Answer 8

Spin paired sublevels filled

Question 9

Electron Affinity

Answer 9

Energy when electron is added. If addition makes more stable, energy given off

Question 10

Electronegativity

Answer 10

How strongly electrons attracted to nucleus of other atoms. Increases across period decreases down group.

Question 11

Dipole

Answer 11

Arrow in molecular diagram points to element with higher electronegativity
