Q

What is a cation?

A

Atoms that lose electrons, they are cations or positive ions

17
Q

What is an anion?

A

An anion is an atom that gains electrons. So they now have an negative charge. The are called anions or negative ions

18
Q

What sort of ion does a metal form?

A

They form positive ions, cations

19
Q

What sort of ion does non metals form?

A

They form negative ions, anions

20
Q

Why don’t Nobel gasses form Nobel gasses?

A

Because they already have their outer shells full

21
Q

What is radioactivity?

A

Unstable atomic nuclei that will spontaneously decompose to form a nuclei with higher stability

22
Q

Properties of alpha radioactivity

A

Skin or paper stops alpha
Charge = +2
Mass = 4

23
Q

Properties of beta radiation

A

Mass = 1/1860
Penetrating power = stopped by millimeters of aluminum
Charge = -1

24
Q

Properties of gamma radiation

A

Mass = 0
Charge = 0
Penetrating power = stopped by several cm of lead or several m of concrete

25
Q

What is half life?

A

Half life is the time it take for half the number of radioactive nuclei within a sample to decay

26
Q

What is a wave?

A

The movement of energy through a medium without any nett movement of the medium

27
Q

What is a transverse wave?

A

Where the particles are moving perpendicular to the direction of the wave

28
Q

What is a longitudinal wave?

A

Where the particles vibrate parallel to the direction of the wave. Sound is an example of a longitudinal wave.

29
Q

What type of wave is light?

A

Light is an example of a transversal wave

30

Q

What are the 3 types of mirrors?

A

Convex-image is larger
Plain-not distorted
Concave-image is smaller

34
Q

What is the focal point of a mirror?

A

The point in space where parallel light rays meet after passing through the lens or mirror

35
Q

What is refraction?

A

The bending of a wave when it enters a thicker or thinner medium (towards or away from the normal)
