In which of the following are the symbols and names for the ions given correctly? a. nh4+: ammonia; h+: hydride b. c2h3o2-: acetate; c2o4-: oxalite c. oh-: hydroxide; o2-: oxide d. po33-: phosphate; po43-: phosphite

The correct answer is Option C.

Explanation:

The ions given in the options are considered as polyatomic ions. This means that they are formed from the more than 2 atoms.

From the given options:

ion is termed as ammonium ions.

ion is termed as hydrogen ion.

Thus, the names are not written correctly.

ion is termed as acetate ion.

is termed as oxalate ion.

Thus, the names are not written correctly.

ion is termed as hydroxide ion.

ion is termed as oxide ion.

Thus, the names are written correctly.

ion is termed as phosphite ion.

ion is termed as phosphate ion.

Thus, the names are not written correctly.

Hence, the correct answer is Option C.

the number of protons in the nucleus of a given element. has slight luster and conducts electricity at high temperatures like metal.but like a nonmetal,boron is brittle and does not conduct electricity well at low temperatures. in graphite, carbon is a soft,brittle solid.it is reflective,ductile,or malleable.

atomic mass = 39

number of neutrons = 20

number of protons= 19

electronic configuration = 1s2 2s2 2p6 3s2 3p6 4s1

the number of electron in first shell = 2

number of electrons in n=3 shell = 8
