this was posted on my 5th bday

this guy kinda cringe

Nicely explained. Thanx mister.

ok sam from glee

It was 8 years old video but still best…… 2020

So how's school everyone.

Im guessing your here from school too

Question: so is a molecule basically a compound or a mixture?

aah, this is what my teacher was talking about.

so when r u making a comeback

1:41 you said it correct there But your Nucleus of hydrogen in your figure is wrong.

thanks so much, I HOPE U CONTINUE

Audience could see your passion for the Chemistry while you are teaching. Thanks for such a simpler explanation in every video.

thx

Thank you! Brilliant explanation.

what's the difference between an atom

00:02

and a molecule if you're wondering this

00:04

you're definitely not alone because this

00:05

is such a common question in chemistry

00:07

so the short answer is atoms are like

00:10

Legos or blocks or bricks and molecules

00:15

are like this stuff that we actually

00:17

build with those blocks of bricks that's

00:19

a short answer let me give you a longer

00:22

answer that might be more useful so

00:25

let's start by talking a little bit

00:27

about atoms there are a few important

00:30

parts of that an atom has a nucleus

00:33

which is made up of protons and neutrons

00:36

that's what I've drawn here with little

00:38

dots and then around the nucleus of the

00:40

atom

00:41

that's where electrons live and

00:43

electrons live in these circular

00:46

neighborhoods called energy levels and

00:49

so I'm drawing in the electrons here

00:51

with these black dots many atoms have

00:55

more than one energy level so they have

00:59

these rings kind of around the nucleus

01:01

like this with these electrons ok so

01:04

here's one atom let me draw another out

01:05

here's a proton here's a neutron this

01:10

Anjelica have one proton and then around

01:14

the nucleus

01:15

here's electron here's a here's an

01:17

energy level where one electron lives ok

01:21

so two atoms here so there are all sorts

01:24

of different types of atom and the type

01:26

of atom that you have depends on the

01:29

number of protons in the nucleus this

01:33

atom over here has eight protons in the

01:36

nucleus which it which means it is an

01:39

atom of oxygen

01:40

this one over here only has one proton

01:43

of nucleus which means that it is an

01:45

atom of hydrogen as I said there are all

01:48

different kinds of atoms and they're

01:51

actually about 100 different kinds and

01:53

when we talk about them is usually

01:55

easier than instead of like writing out

01:57

the name every time we use abbreviations

01:58

so we want to talk about oxygen we write

02:01

an O for hydrogen there's an H we have

02:05

carbon atoms

02:07

represented by a see we have nitrogen

02:09

atoms represented by an N

02:11

chlorine with a CL fluorine with an F

02:14

and so on and so forth all of these ABS

02:18

all these types of atoms are all a

02:20

little bit different I like to think

02:23

about these like Lego blocks right there

02:27

are all these different types of Lego

02:28

blocks but they're all a little bit

02:30

different there are different colors

02:31

they're different sizes some are tall

02:34

others are like flat and skinny and

02:36

that's like these atoms that all have

02:39

slightly different characteristics

02:41

now the the different characteristics of

02:44

these Lego blocks come in handy when we

02:47

actually want to build something with

02:48

them and then we're happy that you know

02:50

one is really skinny or one is red or

02:53

whatever and so that's where the

02:55

different qualities of the atoms come

02:57

into play we take these bricks and we

03:01

build like a little house with and now

03:04

we're talking about molecules so we take

03:10

these bricks and we snap them together

03:12

we can do the same thing with atoms I

03:16

can take an oxygen atom and snap it

03:20

together with two hydrogen atoms and

03:23

when I say snap it together I mean I

03:25

physically connect it that's what these

03:27

little lines here represent and when I

03:28

do that when I have one oxygen connected

03:31

to two hydrogen's I have a molecule of

03:35

water then I call it h2o

03:37

because there are two hydrogen's and one

03:38

oxygen or I can do this I can take a

03:42

carbon atom and snap three hydrogen's to

03:47

it attach another carbon with two

03:50

hydrogen's and then an oxygen and then a

03:53

hydrogen and I have a molecule called

03:57

ethanol which is a kind of alcohol

03:59

that's in beer and wine so the point is

04:02

molecules are made when we take

04:04

individual atoms and physically combine

04:08

them together to make stuff just the

04:10

same way we take individual Lego blocks

04:13

and snap them together to build houses

04:17

or wherever you

04:17

want to make and I'll even take this one

04:19

step for it I show it at the beginning

04:21

that if we could zoom in zillions and

04:23

zillions of times this is what Nana

04:25

would look if we took this water

04:27

molecule and we could zoom in on in

04:29

millions and millions of times this is

04:31

what we'd see and we'd see the oxygen

04:33

atom and the two hydrogen atoms and that

04:35

they're actually all physically

04:37

connected together they're physically

04:40

connected because they're sharing

04:41

electrons forming what's called covalent

04:44

bond you don't already know that don't

04:45

worry about it but they're connected

04:47

here because they're sharing electrons

04:49

and so now they've made like a physical

04:52

connection between each other and

04:55

they've made you know something that's

04:56

like one of these these Lego houses

04:58

where everything gets snapped together

04:59

so anyway that is the difference between

05:03

atoms and molecules atoms are like

05:06

individual building blocks and molecules

05:09

are the stuff that we get when we take

05:11

these building blocks and combine them

05:14

connect them together

Okay but hydrogen has no neutrons in it

@Tyler Dewitt “then what’s the difference between atom and element?” Thank you!

Can't thank you enough for this !🙏💞

man thank u

No one here for biology final test?
