simple: if a nucleus has an imbalance between the number of protons and neutrons it contains, leading it to become unstable, then one or more protons or neutrons will transform into the other to redress the balance. In the process, either an electron or a positron is created and ejected (en-suring that electric charge is conserved How many protons and neutrons are in the nucleus of iron-57?

• Number of neutrons can be equal to or greater than the number of protons because mass number is equal to double the atomic number or greater than double the atomic number. Of course, number of neutrons can be greater than the number of electrons because number of electrons = number of protons in the neutral atom.

15 is the atomic number, so you know phosphorus has 15 protons. Since protons are equal to electrons, there are 15 electrons. The mass is 31.0, which is the # of protons and # neutrons added together. To find the number of neutrons, subtract the atomic # from the mass #. 31-15=16 neutrons inside the nucleus. 15 P Phosphorus 31.0 The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs. The total number of neutrons in the nucleus of an atom is called the neutron number of the atom and is given the symbol N. Neutron number plus atomic number equals atomic mass number: N+Z=A.

In the question we are given, the iron element has undergone a bonding process and it has given away two electrons, to become a cation, that is why it is written as Fe2+. Thus, its electron number will become: 26 - 2 = 24.
Neutrons do not affect the electron configuration, but the sum of atomic number and neutron number (the number of neutrons), is the mass of the nucleus. Atoms of a chemical element that differ only in neutron number are called isotopes . Shell number one can only hold 2 electrons, shell two can hold 8, and for the first eighteen elements shell three can hold a maximum of eight electrons. As you learn about elements with more than eighteen electrons you will find that shell three can hold more than eight.
Atomic Number - Protons, Electrons and Neutrons in Selenium. Selenium is a chemical element with atomic number 34 which means there are 34 protons in its nucleus.Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z.The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
• Fostech complete lowerNeutrons play a major role in the mass and radioactive properties of atoms. You may have read the page on isotopes. Isotopes are created when you change the normal number of neutrons in an atom. Inside the Nucleus You know that neutrons are found in the nucleus of an atom. Under normal conditions, protons and neutrons stick together in the nucleus.

Sometimes the atomic weight is given in the problem and the number of neutrons is blank. Thanks to algebra we can rearrange the above equation to: Number of neutrons = atomic weight - number of protons. Curveball 3: What is its name? The naming system for these goes NAME-MASSNUMBER. For example Molybdenum-97, Uranium-235, Lead-210. The number on the bottom left corner is the atomic number, which tells you the number of protons. The number on the upper left corner is the mass number, which is equal to the neutrons and protons added together. Lastly, the charge is on the upper right corner. If there isn't any number or signs, then it means that atom has no charge and is ...
