Transcript of The Atom
Mass: 1.6755 x 10^-27 kg (~1 amu)
Mass: 1.6726 x 10^-27 kg
mass: 9.109 x 10^-31 kg
quarks - smaller particles
The area around the nucleus of an atom
where its electrons are most likely found
Atomic Number = Protons
Average Atomic Mass
How many neutrons does Na have?
What is this atom?
Atoms of the same element that
have a different number of Neutrons
A charged particle that either has more or less electrons than protons, but not the same number.
The Alkali Metals
Inner Transition Metals
AVERAGE atomic mass
Allotropes - different forms/shapes of the same element
Diatomic molecule- TWO atoms of the same element bonded
ROUNDED Atomic Mass # = Protons + Neutrons
