Question

A compound has a formula = "H2Y". Y denotes a non-metal. State the following:
1. The electronic configuration of Y.
2. The valency of Y.
The bonding present in 'H 2Y'.
4. The bonding present in the compound formed between potassium [39 19K] and 'Y'.
5. The formula of the compound formed between calcium [40 20 Ca] and Y.​

Answer 1

Hi there,

♡ Welcome to brainly family ♡

☆ 1-《 Y 》 is nonmetal have electronic configuration ( nS2- nP4 )

☆ 2-《 Y 》valency is 2

☆ 3- the bond is 2 single covalent bond in《 H2Y 》

☆ 4- the bond in《 K2Y》 is ionic bond

(K) is metal tend to loss 2 electrons and,( Y ) is nonmetal tend to gains 2 electrons

☆ 5- the compound with calcium is

( CaY )

♡ Hope the answer is helpful

Answer 2

1-Y is nonmetal have electronic configuration ( nS2- nP4 )

2- valency is 2

3- the bond is 2 single covalent bond

4- the bond  is ionic bond

(K) is metal tend to loss 2 electrons and,( Y ) is nonmetal tend to gains 2 electrons

5- the compound with calcium is  ( CaY )
