Question

write the formula for the ammonium ion.

• subscripts and superscripts are not supported in answer boxes so they are in normal script.

○ so₄²- is written as so4^2-
○ na₂so₄ is written as na2so4

question 2
write the formula for the perbromate ion.

• subscripts and superscripts are not supported in answer boxes so they are in normal script.

○ so₄²- is written as so4^2-
○ na₂so₄ is written as na2so4

Explanation:

The ammonium ion is composed of one nitrogen atom and four hydrogen atoms with a +1 charge. The perbromate ion is a polyatomic ion with the formula \(BrO_4^-\).

Answer:

1. NH4^+
2. BrO4^-
