He received the Noble Prize in physics for being the first to discover radioactivity as a phenomenon separate from that of x-rays and document the differences between the two.

(a)  

He discovered Roentgen's discovery of x-rays through the fluorescence that some materials emit.

(a)  

She became the first woman to be awarded the Nobel prize.

(a)  

She is the first person to obtain two Nobel prizes when she won the prize for the discovery of Polonium and Radium in 1911.

(a)  

The person who originated or coined the word radioactivity.

(a)  

He created a gadget that measures extremely low electrical currents.

(a)  

They identified radioactive elements.

(a)  

It is energy that originates from a source and travels at the speed of light through space.

(a)  

This energy is coupled with an electric field and a magnetic field, and it has wave-like qualities.

(a)  

It is defined as the emission or transmission of energy in the form of waves or particles through space or a material medium in physics.

(a)  

It is stable if it cannot be changed into a different configuration without the addition of external energy.

(a)  

Out of thousands of nuclides that exist, only (a)   are stable.

It fall into a narrow band when the number of neutrons versus the number of protons for stable nuclei is plotted.

(a)  

It is a narrow band when the number of neutrons versus the number of protons for stable nuclei is plotted.

(a)  

It is a type of radioactive decay in which an atomic nucleus produces helium particles.

(a)  

This mode of decay has only been detected in nuclides far heavier than nickel.

(a)  

It is a type of radioactive decay in which an atomic nucleus emits a fast energetic electron or positron.

(a)  

It is a kind of radioactivity in which some unstable atomic nuclei spontaneously dissipate their surplus energy through an electromagnetic mechanism

(a)  

It is emitted in the most common form of gamma decay, known as gamma emission.

(a)  

The process of emitting gamma rays,
