The only factor that can enhance the bonding caused by the nuclear factors is the third factor in reverse, i.e., when an even number of neutrons and protons are present. These trends combined tend to favor an increasing neutron/proton ratio for high mass number nuclides, and equal number ...
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 numbers 114-112 means that cadmium atoms of greater abundance...
From the periodic table, what is the atomic number of aluminum? (a) 26.98 (b) 13 (c) 18 (d) 39.95 Elements: Elements are pure substances composed of only one type of atoms. They can exist in multiple isotopic forms which can vary in the number of neutrons a...
Isotopes are atoms of the same element that have a different number of neutrons. They can be identified because they will also have a different mass number, or the mass of one atom of the element. Answer and Explanation:1 The mass number for carbon is 12amu. The mass number is the sum...
An atom is composed of three particles -- protons, neutrons and electrons. The number of protons is the defining characteristic of an element, and this number also tells you how many electrons are present in a neutral atom. Therefore, iron -- with an atomic number of 26 -- has 26 proton...
The number written to the right of the element's name is the mass number. 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 ...

An atom is made up of three subatomic particles: protons, neutrons, and electrons. Inside the nucleus of an atom, the positively charged protons and the neutrally charged neutrons are found. Surrounding the nucleus are the negatively charged electrons. The balance between ...
If the number of electrons in an atom varies, the element remains the same, but newionsare produced. If the number of neutrons changes, newisotopesresult. Protons are found together with neutrons in the atomic nucleus. The total number of protons and neutrons in an atom is itsatomic mass ...
