how many protons does selenium have

How many protons neutrons and electrons does selenium have?

This atom of selenium has 34 protons, 45 neutrons, and 36 electrons. The atomic number of an element gives the number of protons found in the nucleus of each atom of that element. The atomic number is the whole number found in the box with each element on the periodic table. Selenium has an atomic number of 34.

How many neutrons does selenium ion have?

Selenium has an atomic number of 34, so it has 34 protons. The mass number is the number of protons plus neutrons. So we would subtract the atomic number from the mass number here to get your number of neutrons. 78-34=44 neutrons.

What has 34 protons and 45 neutrons?

Selenium has 34 protons and 45 neutrons in its nucleus giving it an atomic number of 34 and a atomic mass of 79. Selenium is in Period 4 of the Periodic Table because it has 4 electron shells.

How many protons neutrons and electrons does Selenium 79 have?

How many protons and neutrons does Selenium 80 have?

Diagram of the nuclear composition and electron configuration of an atom of selenium-80 (atomic number: 34), the most common isotope of this element. The nucleus consists of 34 protons (red) and 46 neutrons (blue). 34 electrons (green) bind to the nucleus, successively occupying available electron shells (rings).

How many electrons does Selenium 75 have?

Therefore, the atomic number of Se is 34 and the mass number is 75. Since the atomic number and the number of protons and electrons are the same, the total number of electrons and protons would be 34.

How many neutrons are in an atom of selenium 75?

Since atomic number represents number of protons, that will be 34. Take the difference of the mass number and the atomic number to get the number of neutrons. So, 79-34 will get you 45 neutrons. The number of electrons depends on whether the atom has a charge.

What is proton and neutron?

Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. Neutrons are a type of subatomic particle with no charge (they are neutral). … As a result, a neutral atom must have an equal number of protons and electrons.

What is proton neutron and electron?

Atoms are made of extremely tiny particles called protons, neutrons, and electrons. Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge.

Which is the neutron number?

Atomic number (proton number) plus neutron number equals mass number: Z + N = A. The difference between the neutron number and the atomic number is known as the neutron excess: D = N – Z = A – 2Z.
