Let z = -i = 0 – i
a = 0, b = -1
z lies on negative imaginary Y-axis.
|z| = r = \(\sqrt{a^2+b^2}=\sqrt{0^2+(-1)^2}=1\) and
θ = amp z = 270° = \(\frac{3\pi}2\)
The polar form of z...
Let z = -1 = -1 + 0.i
a = -1, b = 0
z lies on negative real X-axis.
|z| = r = \(\sqrt{a^2+b^2}\) = \(\sqrt{(-1)^2+0^2}\) = 1 and
θ = amp z = 180° = π

Hydrogen atom has only one electron in its valence shell having electronic configuration 1s1
It can acquire stable configuration of helium by sharing this electron with another hydrogen atom.
Therefore, it shares its...
Correct Answer - b
Correct explanation . Due to bigger size of `K^(+)` than `Na^(+)`, it has a weak positive field around it which cannot prevent peroxide ion `(O_(2)^(2-))` to combine...
