#1
Front (Question)

chemical elements

Back (Answer)

an element is a substance that cannot be broken down to other substances by chemical reactions

#2
Front (Question)

matter

Back (Answer)

anything that occupies space and has mass

#3
Front (Question)

compound

Back (Answer)

substance consisting of two or more elements combined in a fixed ratio

#4
Front (Question)

structure and function of compounds

Back (Answer)

can be very different from the elements that make them up

#5
Front (Question)

CHNOPs (also some ions like Ca and K) (3)

Back (Answer)

• carbohydrates=CHO • proteins=CHON • phospholipids=CHONP

#6
Front (Question)

subatomic particles (3)

Back (Answer)

neutrons protons electrons

#7
Front (Question)

atomic number

Back (Answer)

number of protons

#8
Front (Question)

atomic mass

Back (Answer)

mass number

#9
Front (Question)

isotopes (2)

Back (Answer)

• retains all properties and reactivity of the atom but has more neutrons • more neutrons -> more unstable and radioactive it becomes

#10
Front (Question)

chemical bonding (2)

Back (Answer)

• only electrons are involved in chemical bonding - electrons are in orbitals in different electron shells

#11
Front (Question)

orbitals (2)

Back (Answer)

• discrete volume of space where the electrons are most likely to be found • each has a characteristic distance from the nucleus and the further an electron is from the nucleus the higher its energy level

#12
Front (Question)

outermost shell (3)

Back (Answer)

• determines chemical properties of the atom • number of atoms of the other elements that it can combine with • elements are most stable when their outermost shell is full
