Chemistry electrons

for next week test

what is an orbital

a region of space where it is likely to find an electron

where do s blocks have their outer electrons,,,, same for other blocks

in the the s orbital,,, their repective orbitals

what does a s orbital look like

sphere

what does a p orbital look like

propeller

what does a d orbital look like

a daisy

what does the shape of the orbital show

the path (movement) of the electrons in it

what is a subshell

a group of orbitals of the same energy (degenerate)

how many electrons in shells 1 to 4

2,8,18,32

how many orbitals do s shells have and how many electrons are in it

1 orbital with 2 electrons

how many orbitals do p have and how many electrons in their sub shell

3 orbitals and 6 electrons

how many orbitals do d have and how many electrons

5 orbitals and 10 electrons

in the electron sequence what does the big number represent

energy level of shell

what are elements with the same electron configuration called

iso electronic

why do electrons spin

they repel eachother

what is hunds rule

electrons go into p and d orbital singularly first before pairing up

what is the definition of first ionisation energy

the energy required to remove 1 electron from each atom in 1 mole of gaseous atoms of an electron to form 1 mole of gaseous 1+ ions

name the three factors that affect the ionisation energy of an element

atom radius, nuclear charge, electron shielding
