electron configuration

Question 1

Niels Bohr

Answer 1

Came up the idea of electron occupying areas
Studied light spectra

Question 2

Spectroscopy

Answer 2

The use of spectra to identify unknown chemicals
Spectrascopes used to view spectra
Spectrometers used to analyse them

Question 3

Energy Levels

Answer 3

Fixed energy value (amount) that an electron may have

Question 4

Ground state

Answer 4

The electrons occupy the lowest available energy levels

Question 5

Excited State

Answer 5

Electrons occupy the energy levels higher than ground state

Question 6

The frequencies of the light emissions are categorised as

Answer 6

Lyman, Balmer and Paschen

Question 7

lyman series

Answer 7

ultraviolet

Question 8

balmer series

Answer 8

visible

Question 9

paschen series

Answer 9

infrared

Question 10

the absorption spectrum

Answer 10

shows the bands and wavelengths of light that are absorbed by an element

Question 11

FAAS

Answer 11

is used to determine concentrations of contaminants of water such as lead

Question 12

how many sub leve;s does n=1 have

Answer 12

one sublevel

Question 13

how many sub levels does n=4 have

Answer 13

4 sub levels

Question 14

Orbitals

Answer 14

A region in space in an atom where there is a high probability of finding an electron

Question 15

Aufbau Principle

Answer 15

When an element is in its ground state, the electrons occupy the lowest available energy levels

Question 16

Hund’s Rule of Maximum Multiplicity (bus rule)

Answer 16

When two or more orbitals of equal energy are free, the electrons occupy the orbitals in singles

Question 17

Pauli Exclusion Principle

Answer 17

NO more than two electrons may occupy an orbital and they must have opposite spin

Question 18

elements that don’t follow the rules of the d- block elements

Answer 18

COPPER AND CHROMIUM
