Q

Atom Definition

A

Basic building block of matter

17
Q

Element Definition

A

A substance made up of only one type of atom that can’t be broken down into a simpler substance and still maintains its properties

18
Q

Compound Definition

A

A substance made up of at least two different types of atoms chemically bonded

19
Q

Molecule Definition

A

Smallest amount of any substance, made up of 2 or more atoms chemically bonded together

20
Q

What are the 4 common elements to living things

A

Carbon, Hydrogen, Oxygen, and Nitrogen

21
Q

Where are the 4 common elements to living things found

A

They are found practically in every molecular compound of living organisms in different combinations.

22
Q

Which element is known as a principle element

A

Carbon

23
Q

Where is carbon found

A

In all large molecules that living things need to functions

24
Q

Why is carbon so unique

A

It is unique due to its ability to form 4 bonds and how easy it can easily bond with other elements like hydrogen, oxygen, nitrogen, and phosphorus. Also it can form bonds with other carbon atoms to form a large molecule

25
Q

How chemists classify molecules

A

By organic and inorganic

Q

What are lipids

A

Fats, oils, and cholesterol and are a source of energy

33
Q

What are Lipids function in the body

A

Form membranes around cells, release energy, maintain body temperature, and sometimes form hormones
