Introduction to Atoms
Organizing Elements
Metals
Nonmetals & Metalloids
Elements from Stardust
100
This part of an atom carries a positive charge.
What is a proton?
100
Na is this that represents sodium.
What is a chemical symbol?
100
This means that metal can be hammered into rolls.
What is malleable?
100
This element doesn't have the properties of a metal.
What are nonmetals?
100
When electrons are stripped away,this state of matter is created.
What is plasma?
200
This part of an atom floats around the nucleus.
What is an electron?
200
The horizontal rows on the periodic table are know as these.
What are periods?
200
The ability to conduct electricity or heat is called this.
What is conductivity?
200
Coal is an example from tghis family of nonmetals.
What is carbon?
200
This happens when gravity causes two or more nuclei to combine.
What is fusion?
300
The atomic number tells the number of these.
What are protons?
300
The vertical columns on the periodic table are called these.
What are groups?
300
When iron rusts, it displays this chemical characteristic.
What is reactivity?
300
This abundant element has one proton and one electron.
What is hydrogen?
300
This gas has the highest concentration in most stars.
What is hydrogen?
400
If you calculate the total of these 2 parts, you will have calculated the atomic mass.
What protons and neutrons?
400
If an element has an atomic mass of 12 with 6 protons, the amount of neutrons is this.
What are 6?
400
These metals have the highest reactive rate.
What are alkali metals?
400
This substance can conduct eletricity under some conditions but not others.
What is semiconductor?
400
This action creates the heaviest elements after the explosion.
What is a supernova?
500
When atoms with the same number of protons but different numbers of neutrons combine, this is formed.
What is an isotope?
500
This means "in a regular repeated pattern."
What is periodic?
500
These metals have a lower reactivity and are used in building.
What is transitional metals?
500
Helium is an example of this gas type.
What is a noble gas?
500
These are cloud-like region of gases after gases escape from a dying star.
What is a nebula?
