Among all protons and neutrons lie in the nucleus and electrons lies in the outer shell.Answer and Explanation: The total mass of the nucleus is the sum of the mass of protons and neutrons. For a neutral element, number of protons are equal to the number of...Become a member and unlock...
The mass number of an atom is the total number of protons and neutrons contained within the nucleus of the atom. The number of protons determines the element and will always equal the atomic number of that element. The number of neutrons can change and will determine which isotope of that...
While the number of protons must stay the same to qualify as a particular element, there is no restriction on the number of neutrons that can be found in a nucleus. The different isotopes are identified by their mass number, the total of their protons and neutrons.Answer and Explanation: Th...
Calculate the binding energy of a deutron. Given that mass of proton = 1.007825 amu mass of neutron = 1.008665 amu mass of deutron = 2.014103 amu View Solution Free Ncert Solutions English Medium NCERT Solutions NCERT Solutions for Class 12 English Medium ...
2. Purpose of AMU: - AMU is primarily used to compare the relative masses of different isotopes of elements. Isotopes are variants of a particular chemical element that have the same number of protons but different numbers of neutrons. 3. Precise Definition: - The atomic mass unit is defined...
Rhenium (75Re) has two naturally occurring isotopes with atomic weights 184.9530 and 186.9560. What is the percent abundance of the lighter isotope? Average Atomic Mass of an Element and Natural Abundance of Its Isotopes An element is ...
Why are the northern lights so active right now? We're currently experiencing solar maximum, the peak of the sun's approximately 11-year cycle of magnetic activity. This means the sun is producing more sunspots, solar flares and coronal mass ejections (CMEs) — massive bursts of solar mat...
What Is A Dipole Moment? A dipole moment is a measurable quantity, just like mass, volume or speed. It is the characteristic by which dipolar substances can be quantified and differentiated. Dipole Moment Formula The formula to calculate the dipole moment of a simple system with two charges ...
“An ounce of prevention is worth a pound of cure.” At The Truth About Cancer we talk a lot about what causes cancer, and the foods that fight cancer and lower your cancer risk. Now I’m going to talk to you about known, scientifically proven, cancer causing foods that actively increa...
