relative charges of proton nucleon and electron
proton +1 neutron 0 electron -1
relative mass of proton nucleon and electron
proton 1 nucleon 1 electron 1/1836
what is at the top of the nuclide notation
proton and nutron mass
what is proton and nucleon mass called
mass number or nucleon number
what is proton mass called
atomic number or proton number
what are isotopes
same proton diff neutrons
what is at the bottom of the nuclide notation
the proton mass
isoelectric meaning
same no of electrons
isotonic meaning
same no of neutrons
isotopic meaning
same no of protons
how to calculate relative atomic mass
(abundance)(first value) + (abundance)(second value)
how many electrons can orbitals hold
each orbital can only hold a maximum of 2 electrons
what is the principal quantum number
its the size of the orbitals (n =1,2,3,4) 1s 2s 2p 3s 3p 3d
what makes a electron more energetic
the further away it is from the the neutron, the more energetic it is
in what order are orbitals filled
in the ground state, electrons occupy orbitals in terms of increasing energy level, with the lowest energy levels being filled first
what is the order of filling orbitals
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
what if theres, no electrons? 1s^0 how do i draw the elctrons in a box
u js draw a box with no arrows inside
whats electron in a box?
boxes with arrows to represent electyrons starting with the up arrow
Why do successive ionization energies always increase in value?
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).
Effect of electric fields on particles
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.
how to ensure a fair test for electric field experiments
have the same electric field strength
How about neutrons or those with no charge
they go straight, unaffected by the electric field
y do protons go much further than electrons in an electric field and electrons have a much steeper curve
this is because protons are 1836x heavier than electrons
what is the angle of deflection (θ)
The angle of deflection (θ) is the angle between the undeflected path and the deflected path.
