Protons, neutrons and electrons
What is the mass and charge of a proton?
- Mass = 1
- Charge = +1 (positive)
What is the mass and charge of a neutron?
- Mass = 1
- Charge = 0 (neutral)
What is the mass and charge of an electron?
- Mass = 1/2000
- Charge = -1 (negative)
Which particles are found in the nucleus of an atom?

2.8.8
What does the atomic number tell us?

The number of protons
What does the mass number tell us?

The number of protons and neutrons all together
In an atom, what is the relationship between the number of protons and the number of electrons?

Number of protons = the number of electrons
What is the definition of an isotope?

An atom with the same number of protons, but a different number of neutrons

What is the Periodic Table arranged in order of?

Atomic Number
Why did Mendeleev leaves gaps in his version of the Periodic Table?

Because they had not been discovered yet
How did Mendeleev predict the properties of elements that had not yet been discovered?

He looked at the element above and element below the gap
How does the group number link to an atoms electronic configuration?

Group number = number of electrons in the outer shell
How does the period number link to an atoms electronic configuration?
