Chapter One
Has mass, particles and takes up space
The average mass of one atom that elements in AMU's
What is atomic mass
Atoms of the same element with different number's of neutrons
What is isotopes
The electrons which are to end in the outside shell of the atom
What is valence electrons
Molecules that have the same molecular formula but different structural formulas
What is an isomer
The ratio of an objects mass to it's volume
What is density
Particles under the surface of the atom (the building blocks of an atom)
What is subatomic particles
A chemical symbol which shows the atomic number and mass number
What is isotopic notation
The electrons which are not in the outside shell
What is core electrons
Hydrogen = 1 bond
Oxygen = 2 bonds
Nitrogen = 3 bonds
Carbon = 4 bonds
What is HONC - 1234
Takes up space and has mass
What is volume
Negatively charged atom outside of the nucleus
What is an electron
Weighted average of all known isotopes
What is average atomic mass
Ions that don't react with anything
What is noble gases
Two nonmetal atoms share one or more pairs of electrons
What is a covalent bond
Tool used to measure liquids
What is a graduated cylinder
Positively charged atom inside the nucleus
What is a proton
Number of protons
What is atomic number
Ions in group 7a of the periodic table, all reactive and colorful gases
What is halogens
Pairs of electrons being shared between two atoms
What is bonding electron pairs
Has at least two capital letters-two or more elements bonded together to form something new
What is a compund
Neutrally charged atom inside the nucleus
What is a neutron
Particles under the surface of an atom
What is subatomic particles
Ions in group 1a that are all reactive metals- all have one valence electron
WHat is alkali metals
Pairs of electrons not involved in bonding
What is lone pairs
