Total questions: 39
Worksheet time: 21mins
Why do all bonds form?
To fill up the outer shell and become more stable.
To look cool.
To become less stable.
So they don't have to be alone.
What two types of atoms make a covalent bond?
metal atom and metal atom
metal atom and non metal non atom
non metal atom and non metal atom
Atoms are most stable when their outer shell is full or complete.
True
False
What part of an atom is involved in chemical bonding?
proton
neutron
electron
A metallic bond is a bond between ________.
nonmetals
metals
transition metals
metalloids
Which of the following is NOT a property of metals?
Hard
Can conduct electricity
Very brittle (breaks easily)
Malleable (can bend without breaking)
What do electrons do in a metallic bond?
They stay on the metal atom.
They are transferred from atom to atom.
They form a covalent bond with another atom.
They float around freely.
What is meant by the term "sea of electrons"?
It's what we call all the free floating electrons in a metal.
It's what we call electrons that are floating in a liquid.
It's the total number of electrons in a metal atom.
It's the total number of electrons in the ocean.
Why do all bonds form?
so the number of protons equals the number of electrons
so an atom can become unstable
to fill the outermost energy level
Valence electrons are found
in the innermost energy level of an atom
in the middle energy levels of an atom
in the outermost energy levels of an atom
What do atoms that form positive ions tend to do?
lose electrons
gain electrons
lose protons
gain protons
How many valence electrons are shown in the diagram?
16
7
6
2
This refers to the tendency of atoms to prefer to have eight electrons in the valence shell
Octet rule
Valence electron
Electronegativity
Lewis symbol
If an atom loses two electrons what charge will it have?
-1
-2
+1
+2
The positive ions tend to _____________ electrons.
lose
gain
The negative ions tend to _____________ electrons.
lose
gain
What type of elements form cations?
metals
nonmetals
metalloids?
Anions
Gain electrons, has an overall positive charge
Lose electrons, has an overall positive charge
Lose electrons, has an overall negative charge
Gain electrons, has an overall negative charge
Cations
Gain electrons, has an overall positive charge
Lose electrons, has an overall positive charge
Lose electrons, has an overall negative charge
Gain electrons, has an overall negative charge
How does calcium become an calcium ion?
it loses 2 electrons
it gains 2 electrons
How does magnesium become an magnesium ion?
it loses 2 electrons
it gains 2 electrons
How does oxygen become an oxide ion?
it loses 2 electrons
it gains 2 electrons
How many Aluminum atoms are in Al2O3?
3
5
2
1
Cl2
Covalent Bond
Ionic Bond
Which of the following would be the correct formula for a compound of Aluminum and Fluorine?
AlF3
Al2F3
AlF2
AlFI
Why are ions attracted to each other?
Cations and Anions have opposite charges.
Cations think Anions are cool.
The fact that both are metals allows them to mix.
The ions change their electrons again.
