What are atoms?

Back 7

Neutral particles that consist of different proton, electron, and neutron combinations.

Front 8

What are cations?

Back 8

Positively Charged particles that are created when atoms lose electrons

Front 9

What are anions?

Back 9

Negatively charged particles that are created when atoms gain electrons.

Front 10

What are molecules?

Back 10

Larger particles that are created when atoms join together

Front 11

What is matter?

Back 11

anything that has mass and takes up space

Front 12

Pure substance

Back 12

Form of matter which is made of only ONE kind of particle or molecule

Front 13

The particle theory of Matter

Back 13

1) all matter is made of tiny particles

2) All particles of a pure substance are identical

3) the space between particles is large compared to the sizes of the particles themselves

4)Particles of matter are always moving

4) there are forces of attraction that exist between the particles of matter

Hint 13

TILMA

Front 14

What is an element?

Back 14

An element is a pure substance which cannot be further broken down by ordinary chemical means. Since elements are pure substances they must be made up of only 1 kind of particle. The smallest particle of an element is called an atom.

Front 15

What is a compound?

Back 15

A compound is a pure substance which is made of 2 or more different types of elements. Since compounds are pure, they are also made of only 1 kind of particle. The smallest particle of a compound is a molecule.

Front 16

What is a compound?

Back 16

A compound is a pure substance which is made of 2 or more different types of elements. Since compounds are pure, they are also made of only 1 kind of particle. The smallest particle of a compound is a molecule.

NaCl

Back 17

1 Na (sodium) atom joined (bonded) to 1 chlorine atom

Front 18

What is the composition of the following chemical formula?

KMnO4

Back 18

1 potassium atom joined to 1 Magnese atom and 4 oxygen atoms

Front 19

What is the composition of the following chemical formula?

NH4OH

Back 19

1 nitrogen to 5 hydrogen to 1 oxygen

Front 20

What is the composition of the following chemical formula?

Ca(OH)2

Back 20

1 calcium to 2 hydrogen and 2 oxygen

Front 21

Bohr Rutherford Atomic Model

Back 21

1) the atom consists of mostly empty space

2) most of the mass of the atom is located in the central region called the nucleus

3) the nucleus consists of positively charged particles called protons and neutral particles called neutrons.

4) tint negatively charged particles called electrons travel around the nucleus in well defined paths called orbits

Back 35

Back (Definition)

Front 36

Explain the relatedness of protons, electrons, neutrons, atoms, cations, anions, and molecules.

Back 36

Atoms are neutral particles composed of Protons, electrons, and neutrons(particles). If these atoms gain electrons, they become negatively charged and are called cations. If they loose electrons, they become positively charged and are called anions. When atoms join together, they create molecules.
