# How many protons and neutrons are in Fe 58?

The atomic number of iron (Fe) is 26. Hence, Fe will always contain 26 protons, regardless of its isotopes. The atomic mass of the Fe isotope is 58. The mass of an atom (atomic mass) is the sum of its protons and neutrons.

### How many protons neutrons and electrons are present in an atom of iron 54?

This will affect the average mass of an atom of an element. Iron, atomic number 26, has four naturally occurring isotopes. They are: Fe-54, Fe-56, Fe-57, and Fe-58. From the table, we can see the number of neutrons in each isotope's nucleus.
• #### How many protons and neutrons are in iron 57?

(physics) A minor stable isotope of iron, 57 26Fe, having 26 protons and 31 neutrons; it amounts to about 2% of the element in nature.
• #### What family is iron in?

Group 8 is a group of chemical element in the periodic table. It consists of iron (Fe), ruthenium (Ru), osmium (Os) and hassium (Hs). They are all transition metals.
• #### How many protons neutrons and electrons are in copper?

Copper has an atomic number of 29, so it contains 29 protons and 29 electrons. The atomic weight (sometimes called atomic mass) of an atom is approximated by the sum of the number of protons and the number of neutrons in the nucleus of the atom.
B.

### How many electrons protons and neutrons are there in an atom of iron 56?

1. Given the neutral iron atom 56 26Fe, indicate the number of protons, neutrons, and total nucleons in the nucleus, and the number of electrons in orbit around the nucleus. From the designation we can see that the atomic number to the left of the chemical symbol is 26, so there are 26 protons in the nucleus.
• #### How many protons and neutrons are in an atom of Fe 54?

Iron, atomic number 26, has four naturally occurring isotopes. They are: Fe-54, Fe-56, Fe-57, and Fe-58. From the table, we can see the number of neutrons in each isotope's nucleus.
• #### What isotope has 14 protons and 14 neutrons?

For example, silicon has 14 protons and 14 neutrons. Its atomic number is 14 and its atomic mass is 28. The most common isotope of uranium has 92 protons and 146 neutrons. Its atomic number is 92 and its atomic mass is 238 (92 + 146).
• #### What has 18 protons and 22 neutrons?

In this case the number of protons is 18 ,So,the atomic no. is also 18 . Now we need to find the mass number of Argon . A neutral atom of argon also has 22 Neutrons.
