Chapter 1.6 Structure of the atom Flashcards
1
Q
What are atoms made up of?
A
Protons, neutrons and electrons.
2
Q
What are the relative charges of the components of the atom?
A
Proton- +1, electron- -1 and neutron- neutral.
3
Q
What is the relative masses of the components of the atom?
A
Proton- 1, neutron- 1 and electron almost 0 (it would take 2000 electrons to have the same mass as one proton or neutron)
4
Q
How do you calculate the atomic number?
A
Number of protons (=number of electrons).
5
Q
How do you calculate the mass number?
A
Number of protons + neutrons.
6
Q
How do you calculate the number of neutrons?
A
