Front (Question)

how are ions formed?

Back (Answer)

when electrons are transferred from one atom to another

Front (Question)

equations showing the formation of a cation (sodium)

Back (Answer)

Na = Na+ + e-

Front (Question)

equations showing the formation of an anion (chlorine)

Back (Answer)

Cl + e- = Cl-

Front (Question)

what do elements in the same group have in common?

Back (Answer)

they all have the same number of outer elctrons

Front (Question)

what is the trend of charges of ions in the same group?

Back (Answer)

when elements in the same group form ions, they all have the same charge

Front (Question)

what charge ions would group one elements form?

Back (Answer)

1+ ions

Front (Question)

what charge ions would group seven elements form?

Back (Answer)

1- ions

Front (Question)

what are compound ions?

Back (Answer)

ions made up of groups of atoms with an overall charge

Front (Question)

examples of compound ions

Back (Answer)

ammonium, carbonate, hydroxide, nitrate, sulfate

#10

Front (Question)

ionic formula for an ammonium ion

Back (Answer)

(NH4)+

#11

Front (Question)

ionic formula for a carbonate ion

Back (Answer)

(CO3)2-

#12

Front (Question)

ionic formula for a hydroxide ion

Back (Answer)

OH-

#13

Front (Question)

ionic formula for a nitrate ion

Back (Answer)

(NO3)-

#14

Front (Question)

ionic formula for a sulfate ion

Back (Answer)

(SO4)2-

#15

Front (Question)

what is ionic bonding?

Back (Answer)

the net electrostatic attraction between oppositely charged ions

#16

Front (Question)

general ionic structure

Back (Answer)

-ions arranged in giant lattice -cations/anions arranged alternately -3D array -lattice is very strong (many ionic bonds)

#17

Front (Question)

do ionic compounds conduct electricity?

Back (Answer)

ionic compounds conduct electricity when they are molten or dissolved but not when solid

#18

Front (Question)

explanation for ionic compounds conductivity

Back (Answer)

ions in a liquid are free to move and they can carry a charge. in a solid they’re fixed in position by the strong ionic bonds

#19

Front (Question)

ionic compounds melting point

Back (Answer)

ionic compounds have high melting points

#20

Front (Question)

explanation for ionic compounds melting point

Back (Answer)

giant ionic lattices are held together by strong electrostatic forces which takes lots of energy to overcome them

#21

Front (Question)

ionic compounds and solubility

Back (Answer)

ionic compounds tend to dissolve in water

#22

Front (Question)

explanation for ionic compounds solubility

Back (Answer)

water molecules are polar so the water molecules pull the ions away from the lattice and cause it to dissolve

#23

Front (Question)

ionic formula for a sulfite ion

Back (Answer)

(SO3)2-

#24

Front (Question)

when does ionic bonding occur?

Back (Answer)

if there is a big difference in electronegativities i.e. metals and non metals
