Card preview (24)

#1
Front (Question)

three main components of an atom

Back (Answer)

positively charged protons // negatively charged electrons // neutrons with a neutral charge

#2
Front (Question)

which two compents make uo a nucleus of an atom

Back (Answer)

proton & neutron

#3
Front (Question)

what defines the atomic number of an atom

Back (Answer)

number of protons

#4
Front (Question)

atomic mass

Back (Answer)

measure of the weight of an atom // electrons weigh an insignificant amount // atomic mass = atom’s protons + neutrons

#5
Front (Question)

four elements that make up majority of the human body

Back (Answer)

hydogen, oxygen, nitrogen, carbon

#6
Front (Question)

periodic table

Back (Answer)

atoms have a neutral charge, same number of potons and electrons,

#7
Front (Question)

atomic number

Back (Answer)

of protons

#8
Front (Question)

phosphorous atomic number 15– # of electrons in its innermost shell? valence shell? # of electrons needed to fill valence shell?

Back (Answer)

15 electrons /// innermost shell can only hold 2 so 2, // 8 in next shell for 10 total // valence shell has 5, needs 3 more to fill its shell

#9
Front (Question)

ionic bond

Back (Answer)

one atom donates electrons to the other

#10
Front (Question)

ionic bond (charges of the two ions if one is donatingn two electrons to participant)

Back (Answer)

the participant that is losing two electrons becomes more positive (+2), the other participant would gain two electrons become more negative (-2)

#11
Front (Question)

why dont noble gases such as helium, argun, and neon, form bonds with other atoms

Back (Answer)

they all have full valence shells, they dont need electrons to fill their outermost electron shell

#12
Front (Question)

covalent bonds

Back (Answer)

atoms that share electrons

#13
Front (Question)

ionic bond

Back (Answer)

electrons are donated to a receiving participant

#14
Front (Question)

two highly electronegative atoms that often create polar covalent bonds

Back (Answer)

oxygen and nitrogen are highly electronegative

#15
Front (Question)

bonds in water (h20)

Back (Answer)

polar covalent

#16
Front (Question)

bonds in methane (carbon & hyrdogen)

Back (Answer)

nonpolar covalent

#17
Front (Question)

polar

Back (Answer)

unequal sharing of electrons

#18
Front (Question)

polar

Back (Answer)

unequal sharing of electrons oxygen or nitrogen

#19
Front (Question)

ionic / covalent / hydogen [BONDS] srong?

Back (Answer)

ionic and covalent bonds are strong // hydrogen bonds are very weak

#20
Front (Question)

monosaccharides

Back (Answer)

glucose or fructose

#21
Front (Question)

disaccharides

Back (Answer)

sucrose, maltose, lactose

#22
Front (Question)

polysaccharides

Back (Answer)

starch, cellulose, glycogen

#23
Front (Question)

molecule used by humans to store excess glucose

Back (Answer)

eat the plant starch and store excess glucose as glycogen

#24
Front (Question)

carbohydrates

Back (Answer)

are polar, are hydrophilic, dissolve readily in water
