the atom Flashcards
what is an atom
it is the smallest particle of matter
what are atoms made up of
electrons
protons
neutrons
where are protons and neutrons found
in the nucleus
where are electrons situated
orbiting the nucleus
what is the charge for a proton
what is its mass (amu)
a) +
b) 1
what is the charge for a neutron
what is its mass (amu)
a) neutral
b) 1
what is the charge for a electron
what is its mass (amu)
a) —
b) 0
where are electrons found
in shells also known as ENERGY LEVELS or PRINCIPLE QUANTUM NUMBERS (n)
what does the number of shells in a an atom co relate with
the number of shells in a an atom co- relates with its period number in the periodic table
how many electrons can (n=1) carry
n=1 can only carry a maximum of 2 electrons
how many electrons can the remainder of the shells carry
it can carry 8 electrons
what is an orbital
a region of highest probability of finding an electron
nam eten 2 key types of orbitals
s- orbital
p- orbital
S-ORBITAL
its can carry a maximun of how many electrons
2 electrons
S-ORBITAL
how is its shaped
like a sphere
S-ORBITAL
n=1 has how many s-orbitals
is only has an s- orbital
and only one of it
P-ORBITAL
how many sub - orbitals does it and and how many electrons do they each carry
therefor the P-ORBITAL can carry a maximum of how many electrons alltogether
it has 3 sub orbitals
each carry a maximum of 2 electrons
there its can a maximum of 6 electrons all together
P-ORBITAL
name the three sub-orbitals
Px
Py
Pz
P-ORBITAL
how it shaped
like a dumbell
P-ORBITAL
where is it found
its is found in n=2 and upwards
