Question

which state of Be+ hast the same orbit radius as that of the ground state of hydrogen atom​

Answer 1

Answer:

See as we know radius of stationary state of bohr model is given by

Rn=n square× a°

So, for helium it will be

Rn=4×0.5×10^-10

= 2.0×10^-10

Explanation:

Atoms are the basic building blocks of matter which has mass and occupies space. They cannot be chemically subdivided by ordinary means. The word ‘atom’ is derived from the Greek word atom which means indivisible. Matter can be broken into small particles called atoms which are too small to be seen through the naked eye.

As discussed earlier, atoms are composed of three types of particles namely protons, neutrons and electrons. A major proportion of mass of an atom is due to protons and neutrons while electrons have very small mass of about (9.108 X 10-28 grams).Atoms are the basic unit of matter and it is vital to have a thorough knowledge of its components like electrons, protons and neutrons.

We have enlisted the information of various particles along with their charges in the table given below:
