1

What is the difference between isotopes of an element?

The number of neutrons are different

2

Electron Configuration using the sub shell s,p,d,f

1s1,1s2,2s1,2s2,2p1-6,3s1,3s2,3p1-6,4s1,4s2,3d1-10

3

orbitals

s subshell has 1 orbital
p subhsell has 3 orbitals
d subhsell has 5 orbitals
p subshell has 7 orbitals

4

What is an emission spectra and what evidence does it provide for the Bohr model of the atom

The distribution of electromagnetic radiation released by a substance whose atoms have been excited by heat or radiation. Heating a substance excites its protons in which the proton will move to a different orbit changing its colour

5

50 nm

6

Nucleons are

Protons+ Neutrons

7

Neils Bohr model proposed the existence of

specific energry levels for electrons in atoms

8

Shrodenger Quantam mechanics is

subshells for electrons in atom

9

An Emission spectrum shows

Coloured lines on a black background

10

Define isotope

Two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei
