Is H2O2 an element or a compound?
element
compound
An atom that gains or loses an electron becomes
an isotope
a new element
an ion
a molecule
When an atom gains an electron it becomes
negatively charged
positively charged
neurtal
Ionic bonds happen when valence electrons are
shared
too heavy
transferred
Valence electrons are
neutral (no charge)
found in the outer most energy level of the atom
equal to the number of protons
Which type of bonds create compounds?
covalent bonds
ionic bonds
metallic bonds
all type of bonds
Which type of bond occurs between non metals?

In order for a chemical reaction to occur,
there must be an explosion or fire
bubbling or gas must be produced
a new substance must be formed
the substance must turn color
After a chemical reaction occurs, atoms are not created nor destroyed,
just rearranged into a new substance
just changed into different elements
just turned into unstable elements
Most elements bond to create compounds because
their outer electron level is full
they are unstable
they are positively charged
Compounds that share specific valence electrons are formed by
covalent bonds
ionic bonds
metallic bonds
all types of bonds
Compounds or elements that share their pooled valence electrons are
covalent bonds
ionic bonds
metallic bonds
all types of bonds
