OG unit 1.0 Flashcards
Element = ?
Contains only one type of atom
3 components of atom?
Proton
Neutron
Electron
Charges for particles?
Proton = +1
Neutron = neutral
Electron = -1
Which particle has negligible mass? and is only found in the shells?
Electron
Top number of Element = ?
And is also number of = ?
Relative atomic mass number
Neutrons & protons in nucleus
Bottom number of Element = ?
And is also number of = ?
Atomic number
Protons in nucleus
So a valency table is basically like the + and - of ions type shit
Balancing thingy majiggy
(idk just like remember ig?)
Sure
What is dm^3 similar to?
Litres
(don’t gamble)
And what is 1cm^3 similar to?
1 millilitre
IN THIS CASE, how u get volume of 100cm^3 but in dm^3 edition?
u do 100/1000
= 0.1dm^3
Last but not least what is the formula for the concentration?
(just know u can def rearrange for the other shit too)
c = n/v
c = concentration (mol/dm^3)
n = moles (mol)
v = volume (dm^3)
So u know the max electrons in the first shell and second shell right?
How much can the third shell have?
18??? That’s new O_o
In an orbital, 2 electrons spin in?
Opposite directions
When elements react and gain/lose electrons, that means it’s = ?
Ionic bonding
When elements react and share electrons, that is =?
Covalent bonding
Ye u gotta remember bout the drawing of ionic and covalent bondings
I guess
What does the S-orbital look like?
A circle
What does Px-orbital look like?
Infinity symbol
What does Py-orbital look like?
Peanut
What does Pz-orbital look like?
Hourglass diagonal
What order of the orbitals for elemental configuration?
1s
2s
2p
3s
3p
4s
Complex part?
3d
4p
What max amount of electrons in any orbital for the elemental configuration?
2
Max electrons in 1 s-orbital?
2
Max electrons in 3 p-orbitals?
6
Max electrons in 5 d-orbitals?
10
What’s also the other method of writing electronic configuration?
Letter edition?
e.g.
For [Ne]:
1s^2, 2s^2, 2p^6
There’s also another additional thing for noble gases only but idk risk for the bisc
Everytime u get this flashcard, go to page 38 on the booklet just so that u don’t rlly rely too much on flashcards
(it’s about ionisation power and also some common exam questions dere too)
Aight
What 1 mole using Avagrado’s number?
6.02 x10^23
An acid + base = ???
= salt + water/hydrogen
e.g.
Sodium hydroxide + hydrochloric acid –> Sodium chloride + water
(NaOH + HCl –> NaCl + H2O)
Show half equation for ions in a metal
m = m+ plus e-
Show half equation for ions in non-metal
X plus e- = x-
U should also look at page 27 for the dot cross diagram stuff
Yeah i guess….
