Question

ELEMENT MASS NUMBER W Х Y Z NUMBER OF PROTONS - 1613 9 NUMBER OF ELECTRONS 11 16 10 10 17 NUMBER OF NEUTRONS 12 16 13 18 32 26 19 35 17 ( a ) State which of the element ( s ) that ; ( i ) will ionize by loss of electron . ( ii ) will ionize by gain of electron ( iii ) has a negative charge . ( iv ) has a positive charge ( b ) Write the correct electronic configuration of each of the elements . ( ) Deduce the correct formula of the compound formed when ( i ) V reacts with W. ( ii ) W reacts with X. ( d ) What type of bond will exist in a compound formed between ; ( i ) Y and Z ( ii ) X

Answer 1

I will do for only those elements that are clear.

Assuming the elements are

₁₁W

₁₆X

₁₃Y

₉Z

The numbers represent atomic numbers deduced from the data given.

(a) (i) W and W ionizes by loss of electrons

(ii) X and Z

(iii) X and Z

(iv) W and Y

(b) Electron configuration

W = 1s²2s²2p⁶3s¹

X = 1s²2s²2p⁶3s²3p⁴

Y = 1s²2s²2p⁶

Z = 1s²2s²2p⁵

(c) (i) element V is unknown or not present

(ii) W₆X

(d) (i) Y and Z form an ionic bond

(ii) X is a metal hence metallic bonding
