The symbol Z is given to that atomic number, which is also the number of electrons in the atom and determines its chemical properties. Computer Exercise 2.A describes the program ELEMENTS, which helps find atomic numbers, symbols, and names of elements in the periodic table. Generally, the ...
c. atomic mass number Atomic Number: The atomic number of an element represents the number of electrons or the number of protons in the element while the atomic mass represents the sum of neutrons and protons that exist in the element. Answer and Explanation:...
An atom consists of a nucleus and an electron cloud around it. Nucleus consists of protons and neutrons. A neutral atom has equal number of protons and electrons. The number of protons plus the number of neutrons is the mass number of the atom....
As atomic number increases, shells fill with electrons in approximately the order shown at right. WikiMatrix terbium / chemical symbol: Tb / atomic number: 65 / atomic mass: 158.9253 langbot Chromium is a chemical element with symbol Cr and atomic number 24. WikiMatrix technetium (atomic...
There are about ninety elements found on Earth. Each one has a different number of protons, electrons and neutrons. The total number of these subatomic particles held by the respective elements are responsible for their unique properties (including radioactivity). ...
donates 1 to 8 electrons to the metal so that the electronic configuration of the said metal is equal to or not more than two less than the electronic configuration of the next higher rare gas, Y is an anion and n is 0-3, may be used as catalysts in the polymerization of olefines....
Is the atomic weight a whole number? a. Yes, it is the weight of protons, neutrons, and electrons in an atom. b. Yes, atomic weight is the weight of the protons. c. No, it is the mass compared to the mass of carbon-12, when weighted according to abundanc...
Answer to: Calculate the average mass of each isotope by dividing the total mass by the number of particles of that isotope. Refer to data in the...
Determine the energy necessary to bring an alpha particle to the surface of a Tc-99 nucleus. Assume that the Tc-99 nucleus is fixed for this calculat Consider the nucleus. How many protons and neutrons are in the nucleus, and how many orbiting electrons are in ...
