Question

1 . Write the names of the following
compounds: FeS, MgO, NO2 ,NH3. 2. Writ the names for the following elements​

Answer 1

Answer:

1. The compound name will always include the names of the elements that are part of it.

A compound of iron (Fe) and sulfur (S) is ironsulfide (FeS)

A compound of potassium (K) and bromine (Br) is potassiumbromide (KBr)

A compound of sodium (Na) and chlorine (Cl) is sodiumchloride (NaCl)

2. In a compound, the element that is on the left of the Periodic Table, is used first when naming the compound. In the example of NaCl, sodium is a group 1 element on the left hand side of the table, while chlorine is in group 17 on the right of the table. Sodium therefore comes first in the compound name. The same is true for FeS and KBr.

Answer 2

Answer:

FeS = Iron Sulfide

MgO = Magnesium oxide

NO2 = Nitrogen dioxide

NH3 = Animonia
