Question 0

Resonance means

Answer 0

Two or more valid electron dot formulas for the same arrangement of atoms or ions

Question 1

Tripe bonds are ______ than single bonds and _____ than double bonds

Answer 1

Stronger

Shorter

Question 2

Resonance structures are shown by a _____ arrow

Answer 2

Double headed

Question 3

Carbon can have 8 electrons or ___ electrons

Answer 3

4

Question 4

Three exceptions to the octet rule

Answer 4

Expanded octets

Boron forms 3 bonds or six electrons, beryllium has 2 bonds or four electrons

Odd number of valence electrons (NO) can’t get an even number

Question 5

VSEPR

Answer 5

Valence shell electron pair repulsion theory

Due to negative charge we draw them as far away as possible

Question 12

Bent just means

Answer 12

Less bonding groups, like one is probebly a simple electron pair instead of being shared
