What is the rule that elements want to have 8 valence electrons?
Octet rule
Octopus rule
Valence electrons rule
Ion rule
What advantage does an element have when it has a full valence level of 8 electrons?
Greater mass
having more electrons is like having more money
to over power teh effect of the protons
stability
What makes an element an atom (neutral) instead of an ion?
when there are more electrons than protons
When there are more protons than electrons
When the electrons are equal to the protons.
How do can atoms complete the octet rule?
They lose or gain protons
They lose or gain neutrons
They lose or gain electrons in the outer most level
They lose of gain electrons from the inner most level
How many electrons does Na want to gain or lose to complete the octet rule?
It wants to gain 7 electrons
It wants to lose 3 electrons
It wants to lose 1 electron
It want so gain 6 electrons

It wants to gain 3 electrons
It wants to lose 3 electrons
It wants to lose 5 electron
It want so gain 6 electrons
How many electrons does Cl (Chlorine) want to gain or lose to complete the octet rule?
It wants to gain 1 electrons
It wants to lose 7 electrons
It wants to lose 9 electron
It want so gain 10 electrons
How many electrons does Se (Selenium) want to gain or lose to complete the octet rule?
It wants to gain 2 electrons
It wants to lose 6 electrons
It wants to lose 15 electron

Metals tend to _______________ electrons and form __________ ions. These ions are called ______________.
gain, negative, anions
lose, positive, cations
gain, negative, negatrons
lose, positive, positrons
What ion does oxygen form when it gains 2 electrons. Originally Oxygen had 8 electrons and 8 protons.
Protons - electrons = charge.
O-6, it now has 8 more electrons than protons
O-2, It now has 2 more electrons than protons
O+2, it now has 2 more protons than electrons.
What ion does Magnesium form?
Protons - electrons = charge.
Mg-2, gains 2 electrons, it has 2 more electrons than protons.
Mg+2, loses 2 electrons, it has 2 more protons than electrons.
Mg-6, gains 6 electrons, it has 6 more electrons than protons
What ion would F form?
F-1, Because it will gain one electron making it have 1 more electron than proton.
F+7, because it will lose 7 electrons making it have 7 more protons than electrons.
