Electron Configuration

Question 1

Which subatomic particles are inside of the nucleus?

Answer 1

protons and neutrons

Question 2

what is the proton charge?

Answer 2

positive

Question 3

what is the neutron charge?

Answer 3

neutral

Question 4

electron charge and placement

Answer 4

electron cloud, negative

Question 5

which part of an electron makes up the mass? volume?

Answer 5

mass- nucleus (dense)
volume- electron cloud

Question 6

Isotope

Answer 6

number of neutrons changes

Question 7

in a neutral atom which two particles have an equal amount?

Answer 7

protons and electrons

Question 8

anion

Answer 8

negative ion (gains electrons)

Question 9

cation

Answer 9

positive ion (losing electrons)

Question 10

Subshells, orbitals, and electrons

Answer 10

s,1,2
p,3,6
d,5,10
f,7,14

Question 11

Where do you remove electrons from

Answer 11

Highest number in highest subshell

Question 12

which elements round up

Answer 12

any at d4 or d9

Question 13

Isoelectronic

Answer 13

2 atoms of different elements with the same electron configuration (like Ne and Na+)

Question 14

Coulumb’ law formula

Answer 14

F=q/r^2
(F= force of attraction, q=#protons, r^2=energy level)

Question 15

Ionization energy

Answer 15

energy required to remove an electron

Question 16

relation between force of attraction and ionization energy

Answer 16

greater F=greater Ionization energy

Question 17

Steps to determining which element has greater ionization energy

Answer 17

1) compare each atom in terms of which Valence electron is closer to the nucleus
2)if valence electrons are in the same energy level, look at number of protons (less protons=higher IE)

Question 18

on which energy level does it take the most energy to remove an electron

Answer 18

the lowest (closest to nucleus)

Question 19

how do you identify an isotope from a mass spec reading

Answer 19

find the number of neutrons in the largest peak, subtract atomic # from mass
