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...
In an element, the numbers of electrons and protons are equal. Moreover, since they have opposite charges, they cancel each other out and keep the atom neutral. The total number of protons present in the atom of a substance is known as theatomicnumber. Atomic mass refers to a weighted a...
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...
Lithium is a chemical element that is abbreviated 'Li.' Its name comes from the word 'lithos,' which is a Greek word that means 'stone.' Answer and Explanation: The mass number of lithium is 7. The mass number of any element is equal to its number of protons and neutrons. You can ...
The ratio of mass of an electron to that of the mass of hydrogen atom is View Solution Assuming that x is the mass of electron and y is the total mass of protons in 8O18, which of the following equations is correct for calculating the total mass of protons? View Solution The ratio...
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...
The prime function of aquaporins (AQPs) is generally believed to be that of increasing water flow rates across membranes by raising their osmotic or hydrau
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 ...
