as level chemistry 1 and 2 chapter

Electrons in energy levels further from the nucleus have ...... energy than those closer to the nucleus

• less

• more

• the same

• a slightly different

proton has ...... charge

• positive

• negative

• neutral

• optimistic

.................... is the specific distances from the nucleus corresponding to the energy of the electrons

• valency electrons

• sub-shells

• atomic number

• energy levels

....... is the positive electrode

• cathode

• anode

• isotope

• proton

isotope

• same electrons, different protons

• same neutrons, different protons

• same protons, different neutrons

• same mass, different atomic number

how many groups in periodic table

• 23

• 118

• 89

• 18

with the help of which formula we can calculate max. number of electrons in quantum shell

• 2(x+1)

• 2n*2

• 2n+n

• X+2

draw s-orbital

unit of ionisation energy

• kj/mol

• g/mol

• kj/ml

• l/mol

Ionisation.......... across a period and....... down

• stays the same/increases

• increase/increases

• decreases/increases

• increases/decreases
