Question 1

relatiev atomic mass defintition

Answer 1

is the mean (weighted average) mass of an atom compared to 1/12th of the mass of a carbon-12 atom.

Question 2

hwo to calculate average of atoms

Answer 2

(mass1 x abundance1) +(mass2 + abundance2)…./total abundance

Question 3

electronic configaration for cuopper

Answer 3

[Ar]4s0sd10

Question 4

electronic configuration for

Question 5

define first ionisation enery

Answer 5

the enrgy required to remve an electron from each one mole of gaseous atoms

Question 6

ionisatin energ accross a period

Answer 6

increases because more protons so nuclear charge increases so stronger forceof attraction between nucleus and outer eelectrons whilst shielding stays the same

Question 7

first ionisation neegry down a group

Answer 7

deecreases downa group because mro eshileding

Question 8

describe mass spectrometry

Answer 8

High energy electrons from an electron gun are fired at the sample and they knock off an electron from each particle.
A positive ion is formed.
positive ion is accelerated by a negatively charged plate
ions of the same charge have the same kinetic cnergy
heavioer ions have a longer tiem of flight
at detecto r1+ ions gain an electron
te more 1+ ions collide wihtt the detector the higher the current so then gives abundance of thos ions

Question 9

molar substance definition

Answer 9

6.02x10^23 particles of that susbstance
