Nuclear Model of the Atom (1/2 of Nuclear)

Question 1

Protons charge

Answer 1

Positive Charge

Question 2

Neutron charge

Answer 2

No charge

Question 3

Electrons charge

Answer 3

Negative charge

Question 4

Every atom has a _____ nucleus containing smaller sub-_____ particles called _____ and _______

Answer 4

central, sub-atomic, protons and neutrons

Question 5

Electron: Symbol, charge & mass

Answer 5

symbol = e^-
charge = -1
Mass = considered to be 0 (1/840)

Question 6

Proton: Symbol, charge & mass

Answer 6

symbol = p^+
charge = +1
Mass = 1

Question 7

Neutron: Symbol, charge & mass

Answer 7

symbol = n^0
charge = 0
Mass = 1

Question 8

Atoms always have the same number of what?

Answer 8

Protons and Electrons. This is because Atoms are always neutral

Question 9

What orbits the nucleus?

Answer 9

Electrons

Question 10

Nucleon (mass) number = ?

Answer 10

protons + neutrons

Question 11

What are ions?

Answer 11

Ions are charged atoms. They turn into ions through the loss or gain of electrons

Question 12

Proton/Atomic number = ?

Answer 12

Number of protons

Question 13

What is an element?

Answer 13

A substance that is entirely made up of one type of atom

Question 14

What makes an atom unique

Answer 14

Atoms vary by having varying amounts of protons which also affects the number of electrons (since neutron atoms have equal protons/electrons)

Question 15

Different atoms will behave _____ because of the difference in _______/_______ numbers

Answer 15

differently, proton, electron

Question 16

Isotopes

Answer 16

variants of the same atom. they have the same proton/electron number, but they have a different neutron number.

Isotopes therefore have the same proton number but different mass number

Question 17

Nuclear fusion

Answer 17

The process in which two light nuclei combine together and combine to make singular, heavier nucleus releasing a vast amount of energy

Question 18

Nuclear fission

Answer 18

When an unstable, heavy nucleus splits into two smaller nuclei releasing a vast amount of energy in the process

Question 19

Nuclide properties

Answer 19

Nucleon number (sum of protons and neutrons), represented as A, on top of the proton number (number of protons), represented as Z.

This is then placed to the left of a large symbol which would just be the element symbol
