Question 1

Question
Located in the atom are: [blank_start]protons[blank_end] that have a positive charge, neutrons that have [blank_start]no[blank_end] charge, and electrons that have a [blank_start]negative[blank_end] charge
Answer
  • protons
  • no

Answer
  • positive
  • cation

Question 3

Question

Question 6

Question
Two types of covalent bonds are [blank_start]polar[blank_end] and [blank_start]nonpolar[blank_end]
Answer
  • polar

Question 7

Question
Nonpolar is the [blank_start]equal[blank_end] sharing of electrons between 2 atoms
Answer
  • equal

Question 8

Question
Polar bonds are [blank_start]unequal[blank_end] sharing of electrons, this causes small regional [blank_start]negative[blank_end] and [blank_start]positive[blank_end] poles
Answer

Answer
  • polar molecules
  • polar
  • ion

Question 12

Question
