The krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.
What is isotopes?
isotopes are defined as atoms with a constant number of protons but a variable number of neutrons. Despite having different masses and hence having different physical qualities, they have nearly identical chemical properties.
What is stable nuclide?
Since stable nuclides are not radioactive, they do not spontaneously decay into radioactive elements as happens with radionuclides. They are commonly referred to as stable isotopes when such nuclides are discussed in connection to particular elements.
The electron capture process will turn rubidium-83 into krypton-83. When a proton in the nucleus catches an inner electron and creates a neutron, this process is known as electron capture.
Therefore, krypton-83 isotopes below is formed when rubidium-83 undergoes electron capture.

Answer:
nope
Explanation:
an object cant move by itself unless a resultant force acts on it(newton's law of motion )
Answer:
B. direction of rotation of plane-polarized light.
Explanation:
Both R-2-pentanol and S-2-pentanol are isomer and optical active compound . Both are enantiomers and therefore mirror image to each other . They are different only in respect of their optical activity . One of them will rotate the plane of polarisation of polarised light to the right and the other will rotate the plane to the left . The extent of their rotation will be same . When we take a
racemic mixture of the two in the ratio of 1 : 1 , then the mixture will be optically inactive .
So the answer will be B .
