Geologists can use cosmic rays from outer space to piece together the timing of past geologic events, like volcanic eruptions ...

Hence atomic number = 18 Number of protons + neutrons = 18 + 22 = 40. Hence mass number = 40The chemical symbol for argon with its mass number and atomic number is: Isotopes are atoms of an ...

It's so high-energy that the quarks and gluons that make up the visible matter are released from their usual confinement ...

The nucleus of each atom contains protons and neutrons. While the number of protons defines the element (e.g., hydrogen, carbon, etc.) and the sum of the protons and neutrons gives the atomic mass, ...

A neutron star's almost incomprehensible density causes protons and electrons to combine into neutrons—the process that gives such stars their name. The composition of their cores is unknown ...

Neutron activation analysis is a method for the qualitative and quantitative determination of elements based on the measurement of characteristic radiation from radionuclides formed by irradiating ...

Without context, the term "radiation" sometimes refers to any type of radiated energy, including radio waves, microwaves, and visible light. It more commonly describes ionizing radiation, which ...
