Elements and Compounds

elements and compounds

mother can be classified as mixtures and

substances

substances can be elements and compounds

elements and compounds have

similarities

they are both pure substances

homogeneous or have uniform compositions

and

made up of atoms

let us first talk about the elements

elements are the simplest form of matter

they are made up of atoms

atoms are the smallest particles

atoms have three parts the three parts

of atoms are

protons which are positive charge

neutrons which are no charge

and electrons which are negative charge

elements are logically arranged in

periodic table of elements

here is the periodic table of elements

there are 118 elements in the periodic

table some examples are gold

commonly used as jewelry

helium which is the gas inside the

balloons

and mercury which can be found inside

the thermometer

elements have unique properties

no two elements are the same

in these samples of helium tungsten and

chlorine

each has different boiling points

and melting point

when two elements are combined they form

compound

for example

two atoms of hydrogen which are elements

bonded with one atom of oxygen which is

another element

the hydrogen monoxide or h2o is formed

it is commonly known as water

water is a compound

the new substance or compound has

different properties than the elements

they are made of

because

hydrogen and oxygen are both gases

but they form liquid compound

additionally hydrogen is very flammable

and although oxygen is not flammable it

can make the fire to burn hotter and

faster

however the water which is their

combination

kills or extinguishes fire

thus

compounds are made up of elements which

are chemically combined

they have different properties from the

elements they are made of

let us differentiate elements and

compounds

let us begin with their composition

elements are made up of one or more

atoms of the same kind

while

compounds are made up of two or more

different kinds of atoms or elements

now let us move on to their particle the

particles of elements look like this

atoms can be isolated or combined with

the same atoms

while

the particles of compounds combined with

two or more different types of elements

matter separation

elements cannot be divided or broken

down into simpler form

well

compounds can be divided or broken down

into simpler substance by chemical

process

elements is composed of one type of atom

so it cannot be broken down into simpler

form

while

compound is consisted of more than one

element so it can be broken down into

its components

types

the types of elements are

metals

non-metals and

metalloids

in the periodic table of elements

the elements in red color are metals

in green color are non-metals

and in blue color are metalloids

the types of compounds on the other hand

are

acids

bases and

salts

examples

the examples of elements are

or elements in periodic table

and

all combinations of the same kind of

elements while

the examples of compounds are all

combinations of different kinds of

elements

specifically the examples of elements

which are metals are

iron gold and silver

non-metals are

nitrogen

oxygen

and

hydrogen

and metalloids are

boron silicon and germanium

well the specific examples of compounds

are

salt which is a combination of sodium

and chlorine

water

which is a byproduct of hydrogen and

oxygen

and rust

which is formed when iron reacts with

oxygen

now let us have exercise

identify whether the substance is

element or compound

sulfur

is it element or compound

it is

element

carbon dioxide

is it element or compound

it is

compound

sugar is it element or compound

it is

compound

copper

is it element or compound

it is

element

ammonia is it element or compound

it is

compound
