Science Final Flashcards
Substances
Substance is the material, or matter, of when something is made.
ex: tin, sulfur, diamond, water, pure sugar, table salt sodium chloride and baking soda.
ionic bonds
are when an electron is transferred between a metal and non metal.
Shells
the outside part of an atom
valence electrons,
Electrons in to outer shell or energy level
Metals
a material that’s not a non metal
ex, gold silver
nonmetal
Elements that are not metal
ex: water
electron aff
When an atom that is neutral gets an electron
octet rule
Elements bond to fill the valence shell
lons
Protons and Electrons in an element are not equal
Try moving an electron from the metal to the nonmetal. What happens?
The electron stays onto the nonmetal .= they interact
Why is there an attraction between the two ions in this chemical bond?
Because they have opposite charges .
How many electrons will the lithium atom give up to become stable?
one
What happens when atoms share electrons?
they are covalent bonding
diatomic molecule,
having two atoms in the molecule.
valence shell,
the outer shell of the atom
