Total questions: 14
Worksheet time: 13mins
What are ionic bonds?
valence electrons transferred between atoms
valence electrons are shared between atoms
Why do ionic bonds form?
so the number of protons equals the number of electrons
to follow the octet rule and make sure each atom has a full outer energy level
so an atom can become unstable
a new element
a neutral atom
if METALS are more likely to LOSE electrons, they will form ...
anions
neutral atoms
cations
If an oxygen atom has 8 protons (+) and 10 electrons (-), what is it's charge?
O-10
O+8
O-2
O+10
If an aluminum atom has 13 protons (+) and 10 electrons (-), what is it's charge?
Al+3
Al+13
Al+10
Al-10
ionic bonds form between
a metal and nonmetal
two nonmetals
two metals
What is the total charge of an ionic compound?
positive
negative
neutral
if NONMETALS are more likely to GAIN electrons, they will form ...
anions
neutral atoms
cations
In the chemical formula for an ionic compound, which item is written first?
positive ion (cation)
negative ion (anion)
subscript
it's alphabetical
What are the correct rules for drawing a lewis dot structure? (select all that are true)
You can double up the electrons fromt he beginning
It only shows the valence electrons
Only 2 electrons can go on each side of the element symbol
You have to put one electron on all side before doubling up.
Calcium Chloride is an ionic compound, made up from Ca2+ ions and Cl- ions. Which is the correct formula for this compound?
CaCl3
CaCl
CaCl4
CaCl2
