The mass number of an atom is the total number of protons and neutrons in the nucleus of the atom. Thus, the atomic number is also a contributing factor in the mass number.Answer and Explanation: If an atom has
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. ...
To evaluate the appropriate use of chemotherapy for these patients, the surgeon should be familiar with the following: (1) the principles of clinical trials, (2) the proper doses and expected toxic reactions of specific chemotherapeutic agents, (3) the basic principles of combination chemotherapy ...
The greater number of atoms of either one of the given elements has to be interpreted. Concept Introduction : The element symbol : Z A X, where, A (mass number) = no .of protons + no .of neutrons . Z (atomic number) = no . of protons...
The element symbol :ZAX,where, A (mass number) = no.of protons + no.of neutrons.Z (atomic number) = no. of protons. (electrons = protons). Nuclear stability:The nucleus is composed of protons and neutrons. The strongest nuclear force binds ...
An atom has a mass number of 22 and an atomic mass of 20.2. Determine its atomic symbol, atomic...Question:An atom has a mass number of 22 and an atomic mass of 20.2. Determine its atomic symbol, atomic number, and ...
The atomic number of an atom determines what element the atom will be. Each element has a different atomic number based on the number of protons found in its nucleus. The combined number of protons and neutrons will determine the mass number of the atom....
Explanation of Solution Given,1939X Atomic number,Z =19 Mass number,A =39 The atomic number of the element is equal to the number of protons. The mass number is equal to the sum of the number of protons and neutrons. A = p+n ...
The atomic number of an element is defined as the number of protons in the nuclei of the atoms of that element. Answer and Explanation:1 {eq}\\ {/eq} The atomic number of Helium is {eq}Z=2 {/eq}. An atom with one less proton than a helium atom will belong to an el...
The guide includes a body in which a vacuum chamber is formed through which neutrons pass, and having super-mirrors arranged on a plane opposing the vacuum chamber and comprising a neutron-reflecting thin-film. A plate whose surfaces are coated with a neutron-reflecting thin-film divides the va...
