Isotopes are atoms of the same element with the same number of protons and a different number of: A. ions B. molecules C. electrons D. neutrons Because atoms can have the same number of protons but a different number of neutrons: a. elements...
The smallest constituent of matter is atom. Each atom consist of subatomic particles called electrons, protons and neutrons. Protons and neutrons are present in the nucleus and called nucleons. A group of atoms having same number of protons are called as an element. ...

Isotope NameNumber of ProtonsNumber of Neutrons Plutonium-23894144 Plutonium-23994145 This element is solid at room temperature and very heavy. In fact, plutonium is twenty times heavier than water. Furthermore, the element has a bright silver appearance but can oxidize (chemically react with oxygen...
The fast neutron response results from development of the tracks of recoil protons produced mainly by interactions of neutrons in the PADC, with a contribution from interaction in the packaging and dosemeter holder for neutrons of energies greater than about 7 MeV. The thermal and epithermal ...
In physics, a fundamental element often refers to basic constituents of matter like electrons, protons, and neutrons, or to essential principles like force and energy. 12 What determines the unit used in a specific scientific measurement? The unit used in scientific measurements is determined by th...
Thus, all atoms of a given element have the same number of protons, although most elements have several isotopes. These isotopes differ from each other in that the number of neutrons in the nucleus for each isotope is different. Hydrogen, for example, has two stable isotopes. Both isotopes ...
