Many elements combine with hydrogen(valence = 1) to give compounds called hydrides. Use the position of an element in the period

ic table to deduce its valence. Write formulas for these hydrides without using subscripts, for example XH3. If no hydride forms, write "none". What is the formula of the hydride formed by sulfur? What is the formula of the hydride formed by potassium ? ||

Answer:

Explanation:

Use the position of an element in the periodic table to deduce its valence.

The periodic table is a table that groups elements based on their periodic functions. A group is a vertical arrangement of elements. The group number shows the number of elements in the outer shell of the atoms.

The groups runs from 1 to 8. On the periodic table, elements that has more than 4 electrons in their outermost shell will have a valency of 8 less than the number of outermost electrons.

Write formulas for these hydrides without using subscripts, for example XH3. If no hydride forms, write "none".

for group I : NaH, KH,

    group II : MgH2, CaH2,

    group III: BH3, AlH3

  Group 8 do not form hydrides because of their inertness.

What is the formula of the hydride formed by sulfur?

the hydride of sulfur is H₂S

What is the formula of the hydride formed by potassium ?

the hydride of potassium is KH
