Xenon
Melting point is -111.9 °C (161.25 K, -169.42 °F)
Boiling point is -108.1 °C (165.05 K, -162.58 °F)
it has 54 protons and electrons and 77 neutrons and is a noble gas =)
The element with atomic number 56 is Barium. Barium (Ba) is part of the Alkaline Earth Metals - Group 2 Family. Barium has 56 electrons in 6 shells with 2 electrons in the outer shell.
The element with atomic number 54 is Xenon (Xe). Xenon is an Inert Gas in Period 5 of the Periodic Table. Xenon has 54 electrons in 5 shells with 8 electrons in the outer shell.
The element with atomic number 54 is Xenon (Xe). Xenon is an Inert Gas in Period 5 of the Periodic Table. Xenon has 54 electrons in 5 shells with 8 electrons in the outer shell.
If you can locate a periodic table, you can find "54" and find that it is Xenon.

Element 20 is Tin. Element 38 is Strontium. Element 56 is is Barium. Element 100 Fermium. Fermium is artificially created, and has no stable isotopes. In general, there are no stable isotopes heavier than Bismuth (element 83).
This electron configuration is for osmium (Os).
Barium, or Ba, has an atomic number of 56, which means it has 56 protons and 56 electrons (if it is neutral). Its atomic weight is 137.33, which means it has a total of 137.33 neutrons AND protons put together. It has 81 neutrons (137 minus 56).
There are four protons. Also four neutrons and four electrons
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.

Iron is a meta element. Atomic mass of it is 56.
There are four protons. Also four neutrons and four electrons
Iron is a metal element. Atomic mass of it is 56.
Element 20 is Tin. Element 38 is Strontium. Element 56 is is Barium. Element 100 Fermium. Fermium is artificially created, and has no stable isotopes. In general, there are no stable isotopes heavier than Bismuth (element 83).

Iron (Fe) has At No 26 and At Wt 55.85. Is that close enough to 56 for your question.
They are both Isotopes of Barium. The 56 protons tell us that the element is Barium and when you add the neutrons with the protons you get barium138 and barium134. They are both stable isotobes of barium but of all the barium in the world about 72% is barium138 and 2% is barium134.
Barium is a metallic element of atomic number 56, chemical syllable Ba, or a single atom of this element.
This element is caesium (Cs), with the atomic number 56.
Barium has 56 protons.
