dull luster, brittle, poor conductors of heat and electricity
200
These are columns on the periodic table
What is groups/families?
200
This subatomic particle has no weight and lives outside the nucleus.
What are negative neutrons
300
This subatomic particle is found on the outside of the atom, in the cloud or shells
What are electrons
300
This group only needs one more valence electron to feel complete
What is group 17
300
These are rows on the periodic table

This subatomic particle has no electrical charge
What is neutral neutron
400
These subatomic particles holds all the weight of an atom
What are protons and neutrons?
400
This group only needs to give up one valence electron to feel complete
What is group 1

What is Chlorine
500
Explain the three subatomic particles and their electrical charges.
positive protons, neutral neutrons & negative electrons
500
This tells us how reactive an element is.
What is valence electrons/valence shell?
500
This number tells you the number of protons and neutrons in the nucleus
What is the atomic number
500
Explain 3 signs of a chemical reaction
formation of gas, production of heat, change in odor, or color change
500
These subatomic particles have the same mass and have different electrical charges
What are protons and neutrons
