Question

based on the group valency suggest the formula for hydrides of group 15 elements​

Answer 1

Answer:

all the elements of group 15 form hydrides of the type EH3 .Here E can be nitrogen, phosphorous, antimony,arsenic and bismuth

Answer 2

Based on the group valency, the formula for hydrides of group 15 elements​ is $E-H_{3}$.

Explanation:

• A hydride is defined as a molecule where three hydrogen atoms are attached to another element. This central element could be a metal or a non-metal.

• As the elements of group 15 are nitrogen, phosphorus, arsenic, antimony, bismuth. So, the hydrides formed by these elements are $NH_{3}$, $PH_{3}$, $AsH_{3}$, $SbH_{3}$, and $BiH_{3}$.

• This means that general chemical formula of the hydrides formed by the elements of group 15 is $E-H_{3}$, where E can be any element of group 15.
