Question

THE POSITION OF 3 ELEMENTS a,b,and cn the periodic table are shown below;-

group 16 group 17

- -

- A

- -

B C

a)State whther A is a metal or a non metal.

b)state whether C is more reactive or less reactive than A.

c)Will C be larger or smaller in size than A.

d)Which type of ion,cation or anion will be formed by element A?

Answer 1

(a) A is a non-metal.

(b) C is less reactive than A, as reactivity decreases down the group in halogens.

(c) C will be smaller in size than B as moving across a period, the nuclear charge increases and therefore, electrons come closer to the nucleus.

(d) A will form an anion as it accepts an electron to complete its octet.

Answer 2

$\huge\bf\pink{Solution→}$

1. Element A is a non-metal
2. Element C is less reactive than Element A
3. C is smaller in size than B
4. A will form anion
