Warm Up#1-
What is matter? - matter is any object that takes up space and has mass
What is matter made up of? - matter is made up of particles and atoms
Can you see every particle within matter? - yes you can.
Warm Up#2- Atomic Number 4, Atomic Mass 9, Electrons 4, Protons 4, Neutrons 5, Element Beryllium
Warm-Up#3- Atomic Number 10, Atomic Mass 20, Neon

Warm-Up#5- 8 on the valence shell, it is full.
Warm-Up#6- Sodium, no, positive 1 ion
Warm-Up#7- 5 valence electrons. it is not stable. will form a negative ion.
Warm-Up#7- 5 valence electrons. it is not stable. will form a negative ion.
Warm-Up#8- 6 valence electrons, not stable negative ion, can bond with beryllium, magnesium, calcium, strontium, barlum, or radium.
Warm-Up#9- magnesium, 4 no calcium
Warm-Up#10- nitrogen, no it is not stable, it will bond with boron
