An element that has the electron configuration (Ne)3s2 is in the group: a. 2. b. 5. Determine the number of (a) electrons, (b) protons, and (c) neutrons in iron (2656 Fe). What is the ratio of the number of electrons for each atom of lead over one atom of aluminum?
Show that if the 63 electrons in an atom of europium were assigned to shells according to the logical sequence of quantum numbers, this element would be chemically similar to sodium. Use the periodic table to find the atomic mass, atomic number, number of p...
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...
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 ...
The mass number of any element is equal to its number of protons and neutrons. You can figure out the number of... Learn more about this topic: Atomic & Mass Number | Overview & Difference from Chapter 2/ Lesson 1 432K What is atomic number, mass number and atomic mass? Learn what ...
An element has an atomic number of 114 and an atomic mass of 285. How many protons, neutrons, and electrons does a neutral atom of this element have? The atomic number of an element gives the number of and in the atom while the mass number gives the total number of and. ...
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 ...

called the atomic mass number. While theatomic numberalways stays the same. Some elements have atoms with different atomic mass numbers. This is because some elements have a different number of neutrons in the nucleus. Versions of an element with different atomic mass numbers are called isotopes....
