Four elements P, Q, Rand have atomic numbers 12, 13, 14_and 15 respectively. Answer the following … these elements will form the most…
The electronic configuration of following elements are:
P: 2, 8, 2
Q: 2, 8, 3
R: 2, 8, 4
S: 2,8, 5
(i) The element Q has three valence electrons. So it loses 3 electrons to gain its stable gas configuration. So, the valency of Qis 3.
(ii) Since P and Qlooses 2 and 3 electrons to obtain stable gas configuration, So P and Q are metals. Elements R and S either loses or gain electrons to gain its stable gas configuration. So R and S are Non-metals.
(iii)Since P is the most metallic element among P, Q, R and S. So element P will form the most basic oxide.
