Mixtures

Back 12

-mixtures can be homogeneous or heterogeneous

Front 13

John Dalton theory consisted of five general statements based on evidence

Back 13

1. Matter is made up of tiny particles called Atoms

2. All Adams of a given element have the same chemical properties.

3. Ordinary chemical reactions, no atom of any element disappears or is changed into an atom of another element

4. Compounds are formed by the chemical combination of two or more different kinds of atoms

5. A molecule is a tightly bound combination of two or more atoms that act as a single unit

Antoine Lavoisier

Back 14

Proved postulate one and three with the law of conservation of mass.

Back 24

Yes!

Front 25

What does the nucleus of an atom contain?

Back 25

Protons and neutrons.

Front 26

What is the atomic number labeled as?

Back 26

Z.

Every element has a different number of protons there for a different Z number.

Front 27

Where does the atomic number usually appear?

Back 27

Directly above the symbol.

If the Atom is neutral (he has no positive or negative charge) then the number of electrons is the same as the atomic number

Front 28

How to find mass number?

Back 28

Protons plus neutrons

Front 29

Isotopes
