Atomic number Z represents the number of protons per atom. Mass number Z + N is equal to the number of protons Z plus the number of neutrons N present in the nuclei. Mass numbers of the most abundant isotopes are given in order of decreasing abundance. For example, Cadmium Cd-48 mass ...
The atomic number of an element is the number of protons in the nucleus of each atom of that element. The atomic number of each element is different from others. The atomic number of the Gold is 79 and the atomic number of the hydrogen atom is 1. In radioactive decay, the ...
The mass number represents the number of protons plus neutrons in the nucleus of an atom of the element. The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. Five radioactive isotopes of oxygen ...
the order of an element in Mendeleyev's table of the elements; equal to the number of protons in the nucleus or electrons in the neutral state of an atom of an element 更多 英文 词典里"atomic number"的近义词 英文 叙词表中“atomic number"的另一个词是number。 number 更多 atomic numbe...
The number of protons determines the element, but the number of neutrons in the atom of any one element can vary. Each variation is an isotope. A radioactive isotope is one that breaks apart and gives off some form of radiation. About the only isotope of any use is polonium-210. ...
What is the atomic number for polonium? What is the atomic number of an atom that has 6 protons, 6 neutrons, and 6 electrons? How many isotopes does californium have? What is the atomic number for carbon-14? What is the atomic number for tungsten? What is the atomic number of flerovium...
To find the total number of representative elements from the given list of elements, we need to identify which of these elements belong to the s-block and p-block of the periodic table, as these are classified as representative elements.1. <str
12% of 84 = 12% * 84 = 0.12 * 84 = 10.08 What does the number 84 in the name krypton - 84 represent? 84 is the mass number: 36 proton plus 48 neutrons 84 is 14 percent of what number? 84 is 14% of 100*84/14 = 600 ...
The atomic number of an element is equal to the total number of protons in the nucleus of the atoms of that element. The atomic number can provide insight into the electronic configuration of the element. For example, carbon has an electron configuration of [He] 2s2 2p2, since its atomic...
Atomic number is the number of protons inside the nucleus of element. On the other hand, atomic mass number, A of any element is equal to the sum of its protons, P and neutrons N, inside its nucleus. In symbols; A = P + N. ...
