Matter, Periodic Table Trends, Chemical Bonding and Nomenclature

Question 1

Atomic Number

Answer 1

This is equal to the number protons

Question 2

Isotope

Answer 2

Atoms with the same number of protons but they have a different number of neutrons

Question 3

Ion

Answer 3

A charge entity formed when atoms gain or lose electrons

Question 4

Covalent Compounds

Answer 4

• Bad conductor
• Very low melting points
• VESPER shape

Question 5

Ionic Compounds

Answer 5

• Hard
• Brittle
• Good Conductors
• Solids at room temperature
• Very high melting points
• Crystal lattice structure

Question 6

Octet Rule

Answer 6

Elements form stable molecules when they are full (8 electrons)

Question 7

Isoelectronic

Question 8

Polar Covalent Bond

Answer 8

Bonding electrons are shared unequally between atoms where the electrons stay closer to the more electronegative atom.

Question 9

Diatomic Elements

Answer 9

Elements that show up in pairs in nature (H2, O2, F2, Br2, N2, I2, Cl2)

Question 10

Covalent Bond

Answer 10

Bonding electrons are shared equally through single, double or triple bonds

Question 11

Ionic Bond

Answer 11

A complete transfer of one or more valence electrons, full charges on resulting ions

Question 12

Single, Double, Triple bonds

Answer 12

Single: happens when two atoms share one pair of electrons
Double: forms when two atoms share two pairs of electrons
Triple: happens when three atoms share three pairs of electrons

Question 13

Activity Series

Answer 13

The chart that determine whether or not an element is bumped out during single displacement.
