Question

The radius of hydrogen atom is 0.53×10 10m.Convert in cm​

Answer 1

Answer:

Given that,

Radius of hydrogen atom is

r=0.53\times10^{-10}\ mr=0.53×10

−10

m

We know that,

Conversion in meter,

1\ Angstrom =10^{-10}\ m1 Angstrom=10

−10

m

1\ cm=10^{-2}\ m1 cm=10

−2

m

1\ mm=10^{-3}\ m1 mm=10

−3

m

1\ nm=10^{-9}\ m1 nm=10

−9

m

We need to calculate the radius in cm, mm and nm

Using conversion method

Radius in cm

r=0.53\times10^{-10}\times100r=0.53×10

−10

×100

r=0.53\times10^{-8}\ cmr=0.53×10

−8

cm

Radius in mm,

r=0.53\times10^{-10}\times1000r=0.53×10

−10

×1000

r=0.53\times10^{-7}\ mmr=0.53×10

−7

mm

Radius in nm,

r=0.53\times10^{-10}\times10^{9}r=0.53×10

−10

×10

r=0.53\times10^{-1}\ nmr=0.53×10

−1

nm

r=0.053\ nmr=0.053 nm

Hence, (a). Radius of hydrogen atom is 0.53\times10^{-8}\ cm0.53×10

Answer 2

Explanation:

The radius of hydrogen atom=0.53×10^-10 m

=0.53×10^-10×10² cm

=0.53×10^-8 cm
