What element is named after enrico fermi?
The name of the chemical element fermium is derived from the name of the Italian physicist Enrico Fermi. Enrico Fermi contributed to the creation of the first nuclear reactor in Chicago, 1942; also Fermi was a Nobel prize laureate.
What element has 102 neutrons and 70 electrons?
Perhaps Ytterbium, which has 103 neutrons and 70 electrons.
What is an atom with more or fewer neutrons than atoms of the same element?
An atom of a certain element with a different number of neutrons compared with the common form of the element is called an isotope. Isotopes have the same number of protons and electrons in an atom, but a different number of neutrons (which means that they have a different atomic mass number).
What are the correct parts of an atom?
There are three parts to an atom. The nucleus consists of a proton or a combination protons and neutrons. The number of protons is the atomic number, and determines the element. For example, hydrogen has one proton. Helium has two protons and two neutrons. Varying numbers of neutrons represent different isotopes of that element. Deuterium is hydrogen with an additional neutron. The number of protons is generally matched by the number of electrons. If there is an imbalance, an ion (charged element or molecule) is the result. Electrons have a tiny fraction of the mass of either protons or neutrons.
The mass number of an atom is 234 and the atom has 60.0 more neutrons than protons what element is it?
Francium 2x + 60 = 234 x = 87 protons. So you have to have 147 neutrons. Francium has 87 protons, and the neutrons come from the isotope.
What is the number of neutrons in The element fermium?
157
How many neutrons protons and electrons does fermium have?
Fermium has 100 protons and electrons. Number of neutrons = Atomic mass of an isotope - Atomic number of the element The atomic number of fermium is 100; but fermium has 17 isotopes, each with a different number of neutrons. For the most stable isotope of fermium, 257Fm: protons-100 electrons-100 neutrons-157 atomic mass per unit (AMU)-257

Is fermium found in Earth's crust?
Fermium is an artificial element.
What is the standard state of the element of fermium?
Fermium is a solid metal.
What is the nucleus of fermium?
The nucleus of fermium contain 100 protons.For each isotope the number of neutrons is different.Number of neutrons = Mass number of an isotope - 100
What family does element fermium belong to?
Fermium is a member of the actinoids family.
Can you find fermium deep within earth?
Fermium is an artificial element.
