The electronegativity of following elements increases in the order of?
N, Si, C, P
P, Si, N, C
Si, P, C, N
C, N, Si, P
In general electronegativity increases across a period from left to right and decreases down the group.
Question 17 Arrange the following elements in the order of their decreasing metallic character Na, Si, Cl, Mg, Al (a) Cl > Si >Al > Mg >Na (b) Na >Mg >Al >Si > Cl (c) Na > Al > Mg > Cl > Si (d) Al > Na> Si > Ca> Mg
Considering the elements B, C, N, F, and Si, the correct order of their non-metallic character is: (a) B > C > Si > N > F b) Si > C > B > N > F (c) F > N > C > B > Si d) F > N > C > Si > B
Arrange the following elements in the order of their abundance in Earth's crust:
Aluminium - Al, Silicon - Si, Oxygen - O, Iron - Fe.
