OG unit 1.0

Question 1

Element = ?

Answer 1

Contains only one type of atom

Question 2

3 components of atom?

Answer 2

Proton
Neutron
Electron

Question 3

Charges for particles?

Answer 3

Proton = +1
Neutron = neutral
Electron = -1

Question 4

Which particle has negligible mass? and is only found in the shells?

Answer 4

Electron

Question 5

Top number of Element = ?
And is also number of = ?

Answer 5

Relative atomic mass number
Neutrons & protons in nucleus

Question 6

Bottom number of Element = ?
And is also number of = ?

Answer 6

Atomic number
Protons in nucleus

Question 7

So a valency table is basically like the + and - of ions type shit

Balancing thingy majiggy

(idk just like remember ig?)

Answer 7

Sure

Question 8

What is dm^3 similar to?

Answer 8

Litres
(don’t gamble)

Question 9

And what is 1cm^3 similar to?

Answer 9

1 millilitre

Question 10

IN THIS CASE, how u get volume of 100cm^3 but in dm^3 edition?

Answer 10

u do 100/1000
= 0.1dm^3

Question 11

Last but not least what is the formula for the concentration?

(just know u can def rearrange for the other shit too)

Answer 11

c = n/v

c = concentration (mol/dm^3)
n = moles (mol)
v = volume (dm^3)

Question 12

So u know the max electrons in the first shell and second shell right?
How much can the third shell have?

Answer 12

18??? That’s new O_o

Question 13

In an orbital, 2 electrons spin in?

Answer 13

Opposite directions

Question 14

When elements react and gain/lose electrons, that means it’s = ?

Answer 14

Ionic bonding

Question 15

When elements react and share electrons, that is =?

Answer 15

Covalent bonding

Question 16

Ye u gotta remember bout the drawing of ionic and covalent bondings

Answer 16

I guess

Question 17

What does the S-orbital look like?

Answer 17

A circle

Question 18

What does Px-orbital look like?

Answer 18

Infinity symbol

Question 19

What does Py-orbital look like?

Answer 19

Peanut

Question 20

What does Pz-orbital look like?

Answer 20

Hourglass diagonal

Question 21

What order of the orbitals for elemental configuration?

Answer 21

1s
2s
2p
3s
3p
4s

Complex part?
3d
4p

Question 22

What max amount of electrons in any orbital for the elemental configuration?

Answer 22

2

Question 23

Max electrons in 1 s-orbital?

Answer 23

2

Question 24

Max electrons in 3 p-orbitals?

Answer 24

6

Question 25

Max electrons in 5 d-orbitals?

Answer 25

10

Question 26

What’s also the other method of writing electronic configuration?

Answer 26

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

Question 27

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)

Answer 27

Aight

Question 28

What 1 mole using Avagrado’s number?

Answer 28

6.02 x10^23

Question 29

An acid + base = ???

Answer 29

= salt + water/hydrogen

e.g.
Sodium hydroxide + hydrochloric acid –> Sodium chloride + water
(NaOH + HCl –> NaCl + H2O)

Question 30

Show half equation for ions in a metal

Answer 30

m = m+ plus e-

Question 31

Show half equation for ions in non-metal

Answer 31

X plus e- = x-

Question 32

U should also look at page 27 for the dot cross diagram stuff

Answer 32

Yeah i guess….
