Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
The element with 72 electrons is Hafnium (Hf). Hafnium has an atomic weight of 72 and is a period 6, group 4 transition metal. It is the first element after the Lanthanides. Hafnium has 72 electrons in 6 shells with 2 electrons in the outer shell.
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
This electron would have 51 protons and 51 electrons. The number of electrons in an atom is equal to the number of protons, as atoms are electrically neutral.
chromium
32 protons, 32 electrons. Ge-72 isotope has 40 neutrons

The atomic number of an atom tells you how many protons are present in the nucleus. So there are 50 in the element. By the way, an element with 50 protons and 70 neutrons (120-50) is a stable form of Tin.
* Number of Electrons: 72 * Number of Neutrons:106 * Number of Protons: 72 * Number of Electrons: 72 * Number of Neutrons: 106 * Number of Protons: 72
the atomic number of hafnium is 72, protons? 72, neutrons? 106, electrons? 72
Atoms have 3 parts: Protons, Neutrons, and Electrons. In a neutral atom, the atomic #= number of protons, and everything else is equal to it. For example: Hafnium, Atomic#=72= 72 protons, 72 neutrons, 72 electrons= neutral atom.
The atomic number of zinc is 30. So there are 30 protons, 30 electrons in zinc.
This electron would have 51 protons and 51 electrons. The number of electrons in an atom is equal to the number of protons, as atoms are electrically neutral.
chromium
Protones = 51 Electrones = 49 Neutrones = 70 or 72
32 protons, 32 electrons. Ge-72 isotope has 40 neutrons
Hafnium has 72 electrons and protons; the number of neutrons is different for each isotope and depend on atomic mass of the isotope.
The mass number is the amount of protons and neutrons in an element. The atomic number is equal to the amount of protons. Therefore to get the number of protons from the given information, you would subtract 37 from 72 which gives you 35 protons aka its atomic number!
