Question

Atomic number of element Zis 16 i] State the period & group to which Z belongs, ü) Is Zametal or a non-metal
ii] State the formula of the compound between Z & Hydrogen. What kind of compound is this.

Answer 1

Answer:

An element Z has atomic number 16

Z is a non-metal. 3. Formula between Z and hydrogen is H2Z. The kind of compound is covalent.

Answer 2

Atomic number = 16

Configuration = ( 2, 8, 6)

period number is represented by the number of occupied shells = 3

group number is represented by

10+ no. of valence electrons if no. of valence electrons > 2 = 16

Z is a non metal because it can gain 2 electrons to achieve the noble gas configuration so it is electronegative.

Formula of compound formed with hydrogen = H2Z

it will be a covalent compound as it is formed by sharing of electrons.

Z is actually Sulphur...

There you go :)
