What is an ion?
An atom that has gained or lost electrons
Type of elements that form ionic bonds together
metal and a nonmetal
What are Metals?
Type of elements that form metallic bonds
What is the charge of an atom that loses electrons
Positive
What is an example of an ionic compound?
NaCl
What are valence electrons?
Electrons in the outermost energy level
What happens to electrons in an ionic bond
electrons are transferred
What happens to electrons in metallic bonding
They move freely.
What is the charge of an atom that gains electrons
negative
Type of bond found in metals
metallic bond
What is an ionic bond?
Bond formed by the attraction between oppositely charged ions
What forms after an atom loses or gains electrons
ions
Why metals can conduct electricity
Because electrons can move freely.
If an atom loses 2 electrons, what is its charge?
What happens to valence electrons in ionic bonding?
They are transferred.
What is a metallic bond?
Type of bond where electrons move freely between atoms
Why ionic compounds form strong structures
attraction between positive and negative ions
Why metals are able to bend without breaking
atoms can slide past each other
If an atom gains 3 electrons, what is its charge?
-3
Which type of element usually gains electrons?
nonmetals
What is an ionic compound?
A substance made of positive and negative ions bonded together
Why ionic compounds are often hard and brittle
because shifting causes like charges to repel
Name one property of metals caused by metallic bonding
conductivity / flexibility / shininess
What determines the charge of an ion
the number of electrons gained or lost
Which type of element usually loses electrons?
metals
