These are found on the left side of the periodic table and can be very reactive.
What are metals?
400
The majority of the elements in the periodic table that are good conductors of electric current and heat

500
Atoms of an element that have the same number of protons but a different number of neutrons
What are isotopes?
500
This can be predicted based on the element's location in the periodic table

Metals that are hard and shiny with high melting points and high densities. Found in Groups 3 to 12
What are transition metals?
500
Neon and Argon are two of these
What are noble gases?
500

What is semiconductor?
500

I am the "modern model" of the atom. I have an atmospheric name.

The Cloud Model
