All matter consists of practicals called?
All matter consists of atoms. each form of matter has to contain at least one atom. Atoms are the beginning of a particle.
100
What is a NUCLEUS made up of?
Protons, Neutrons.
100
How many atoms fit on the tip of a pin?
Atoms are extremely small. The tip of a pin can hold 1 million atoms.
100
how many neutrons are in this element?
141-146
100
Where are electrons located in an atom?
Electrons are located on the outside of an atom. The protons keep the electrons in place.
200
What is the three key definition points of an element?
1. Elements consist of only one kind of atom
2. Cannot be broken down into a simpler type of matter by chemical means
3. Can exist as either atoms or compounds of a molecule.
200
Besides protons and neutrons, what other part is missing from an atom?
Electrons
200
What Atoms consist of three things?
Protons, Neutrons, and electrons
200
how many protons in this atom
92
200
Why must there always be an equal amount of protons and electrons.
The proton's positive charge holds the electron's negative charge in place. Each proton can only hold one electron in place.
300
why cant you trust atoms?
because they make everything up
300
How do you describe a BOHR MODEL?
1. A Bohr Model is a 2-dimensional diagram of an atom.
2. The Bohr Model shows the nucleus with the protons and neutrons inside.
3. The Bohr Model shows how many rings/shells the atom has.
4. The Bohr Model shows how many electrons are on each shell/ring.

tIf H20 is water what is H204?
Drinking, bathing, washing, swimming. . .
300
What holds the protons and neutrons together inside the nucleus?
MESSON is what keeps protons and neutrons together. Think of it as the super glue of the nucleus?
300
What is the outermost set of electrons called?
Valence Electrons
400
When you see a molecule description, like H2O, what does the 2 represent. 
The number represents how many atoms are represented, from the symbol before the #. In the case of H2O, there would be 2 hydrogen atoms and one oxygen atom.
400
Can all atoms connect with each other.
No, only atoms that have space available, on its outer shell, can join other atoms. Like oxygen There are a total of 8 electrons. Two of those electrons fit in the first ring. That means 6 fit in the second ring. The second ring holds up to 8 electrons, leaving 2 spaces available.
400
what is archemedes' atomic theory.
he thought that everything is 4 elements. fire water air and earth.
400
How many different Quarks are there in a NEUTRON?
There are 6 different types of Quarks
400
Which atoms are always laughing?
Helium.... He He

what is the atomic symbol of this element
U

What electrical charge do a proton, electron, and neutron have?
A positive charge, while electrons have a negative charge, and neutrons have no charge.

What do you do with dead chemists?
Barium

All matter/mass is made up of what particles?
Atoms

what is the first atomic theory
the first theory was made by democritus and they acted like legos.
