Neutrons and protons cannot be removed from nucleus from chemical reactions because they are strongly held together but nuclear reactions are strong enough to separate them. Hence option A is correct.
The equation for Kinetic Energy is KE = 1/2 m v^2, where m is the mass, and v is the velocity. The velocity in this equation is squared, which means that it is exponential. That means that as the velocity increases, you will be multiplying by a bigger and bigger number! KE = 18 joules!
He produced the first orderly arrangement of known elements, he used patterns to predict undiscovered elements
The red end of the visible spectrum has the longer wavelength while the blue end of the visible spectrum has the higher frequency.
