1 of 13
Name the three types of particle that an atom is made of
proton, nuetron and electron
2 of 13
What is the charge and the mass of a proton?
a relative mass of 1, and a charge of +1
3 of 13
What is the charge and the mass of a nuetron?
a relative mass of 1, and a neutral charge
4 of 13
What is the charge and mass of an electron?
a relative mass of 1/2000 and a relative mass of -1
5 of 13
Where is it that you find protons and nuetrons?
In the nucleus
6 of 13
Define mass number
the total number of protons and nuetrons in an atom
7 of 13
Define relative atomic mass
The ratio of the average mass of one atom of an element to one twelfth of the mass of a carbon-12 atom
8 of 13
Define atomic number
The number of protons in the nucleus which identifies the atom.
9 of 13
What is an ion?
A charged particle.
10 of 13
What is an isotope?
elements with different numbers of neutrons in the nucleus
11 of 13
What is it that has an effect on the chemical reactions of an element?
the electronic configuration
12 of 13
Why is it that isotopes have similar chemical reactions but different physical properties?
because they have the same electronic configuration, but the mass of the isotopes are different so they will have different physcical properties
