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
  • negative

Question 2

Question
When an atom loses an electron it becomes more [blank_start]positive[blank_end] and becomes a [blank_start]cation[blank_end]
Answer
  • positive
  • cation

Question 3

Question
When an atom gains an electron it becomes more [blank_start]negative[blank_end] and becomes an [blank_start]anion[blank_end]
Answer
  • negative
  • anion

Question 4

The atomic number is relative to the number of [blank_start]protons[blank_end] the atom has
Answer
  • protons

Question 5

Question
Covalent bonds are bonds where electrons on the outmost ring are [blank_start]shared[blank_end]. A covalent bond is generally known as a [blank_start]strong[blank_end] bond.
Answer
  • shared
  • strong

Question 6

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

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
  • unequal
  • negative
  • positive

Answer
  • Hydrogen
  • weak

Question 11

Question
Van der Waals forces is the weak attractive force between 2 [blank_start]polar molecules[blank_end] or a [blank_start]polar[blank_end] molecule and an [blank_start]ion[blank_end]
Answer
  • polar molecules
  • polar
  • ion

Question 12

Question
[blank_start]Solute[blank_end] is a substance dissolved in liquid
Answer
