proton +1
neutron 0
electron -1

Question 2

Answer 2

proton 1
nucleon 1
electron 1/1836

Question 3

what is at the top of the nuclide notation

Answer 3

proton and nutron mass

Question 4

what is proton and nucleon mass called

Answer 4

mass number or nucleon number

Question 5

what is proton mass called

Answer 5

atomic number or proton number

Question 6

what are isotopes

Answer 6

same proton diff neutrons

Question 7

what is at the bottom of the nuclide notation

Answer 7

the proton mass

Question 8

isoelectric meaning

Answer 8

same no of electrons

Question 9

isotonic meaning

Answer 9

same no of neutrons

Question 10

isotopic meaning

Answer 10

same no of protons

Question 11

how to calculate relative atomic mass

Answer 11

(abundance)(first value) + (abundance)(second value)

Question 12

how many electrons can orbitals hold

Answer 12

each orbital can only hold a maximum of 2 electrons

Question 13

what is the principal quantum number

Answer 13

its the size of the orbitals (n =1,2,3,4)
1s 2s 2p 3s 3p 3d

Question 14

what makes a electron more energetic

Answer 14

the further away it is from the the neutron, the more energetic it is

Question 15

in what order are orbitals filled

Answer 15

in the ground state, electrons occupy orbitals in terms of increasing energy level, with the lowest energy levels being filled first

Question 16

what is the order of filling orbitals

Answer 16

aufbau principal
1s
2s 2p
3s 3p 3d
4s 4p 3d 4f

1s > 2s > 2p > 3s > 3p > 4s >3d
so the 4s is filled b4 3d

Question 17

what if theres, no electrons? 1s^0 how do i draw the elctrons in a box

Answer 17

u js draw a box with no arrows inside

Question 18

whats electron in a box?

Answer 18

boxes with arrows to represent electyrons starting with the up arrow

Question 19

Why do successive ionization energies always increase in value?

Answer 19

The successive ionisation energies of an element increase with the removal of each electron as it experiences increasing net electrostatic attraction to the increasingly positively charged ion. The positive charge of the nucleus remains constant, but there are fewer remaining electrons providing electrostatic repulsion between negative charges (in electrons).

Question 20

Effect of electric fields on particles

Answer 20

As opposite charges attract, the electric field exerts a force on charged particles that accelerates the charged particles towards the oppositely charged electrode and away from the similarly charged
electrode.

Question 21

how to ensure a fair test for electric field experiments

Answer 21

have the same electric field strength

Question 22

How about neutrons or those with no charge

Answer 22

they go straight, unaffected by the electric field

Question 23

y do protons go much further than electrons in an electric field and electrons have a much steeper curve

Answer 23

this is because protons are 1836x heavier than electrons

Question 24

what is the angle of deflection (θ)

Answer 24

The angle of deflection (θ) is the angle between the undeflected path and the deflected path.

Question 25

how to calculate angle of deflection (θ)

Answer 25

it is directionally proportionate to charge / mass

Question 26

what makes a particle travel further and have a smaller angle of deflection in an electric field

Answer 26

The greater the mass of a particle, the smaller the angle of deflection. If all particles are travelling at the same speed, then particles with larger mass have higher momentum and undergo less deflection

Question 27

what makes a particle travel lesser and have a bigger angle of deflection in an electric field

Answer 27

The greater the charge of a particle, the greaterthe angle of deflection, because an increased charge
increases the attraction to the oppositely charged electrode.
