Constituents of the atom

Question 1

Which particles can be found in the nucleus of the atom?

Answer 1

Protons and neutrons

Question 2

What force holds the nucleus together?

Answer 2

The strong nuclear force

Question 3

What is the charge of the Proton?

Answer 3

+1.6 x 10^-19 C

Question 4

What is the mass of the proton?

Answer 4

1.67 x 10 ^-27 kg

Question 5

What is the charge of the neutron?

Answer 5

0!

Question 6

What is the mass of the neutron?

Answer 6

1.67 x 10^-27 kg.

This is the same as the Proton.

Question 7

What is the charge of the electron?

Answer 7

This is the opposite of the proton.

Question 8

What is the mass of the electron?

Answer 8

9.11 x 10^-31 kg

Question 9

What does the nucleon number include?

Answer 9

Protons and neutrons

Question 10

How do you calculate specific charge?

Answer 10

1) Calculate the actual mass and actual charge.
- Actual mass = relative mass x mass of particle
- Actual charge = relative charge x charge of particle

2) Divide actual charge by actual mass.

Question 11

What is the specific charge of a none ionic atom?

Answer 11

0

Question 12

How do you calculate the specific charge of an ion?

Answer 12

In an ion, an electron has been lost or gained, so you add or subtract the charge of an electron from 0.

Answer 24

0

Question 25

What is the actual charge of electrons?

Answer 25

-1.6 x10-19 C

Question 26

What is an isotope?

Answer 26

Isotopes are atoms which have the same number of protons but different numbers of neutrons

Question 27

What is the proton number (Z) of an atom?

Answer 27

The number of protons they contain

Question 28

What is the nucleon number (A) of an atom?

Answer 28

The number of nucleons their nucleus contains ( nucleon number = number of protons + number of neutrons)

Question 29

How do you work out specific charge?

Answer 29

Specific charge ( Ckg-1 ) = Charge ( C ) / Mass ( kg )
