How many electrons does lutetium have?
To find electrons we must first find the atomic number of lutetium, which can be found below the lutetium symbol.Lutetium has an atomic number of 174.97. Round to 175.Atomic number is equal to amount of protons.And in a neutral atom amount of protons is equal to the amount electrons.Lutetium has 175 electrons.Thanks to Mr. Jernigan for teaching me in Chemistry!!

How many unpaired electrons does Lutetium have?
Lutetium (Lu) has no unpaired electrons because it is a transition metal and its electron configuration ends in a fully-filled d subshell.
What is one chemical property of lutetium?
Lutetium has the oxidation state +3.
Is lutetium radioactive?
For most practical purposes, lutetium can be regarded as stable, though it is slightly radioactive. 97.41% of lutetium found in nature is stable, and 2.59% is of an isotope with a half life of 37,800,000,000 years. Like all other elements, lutetium has synthetic radioactive isotopes.
What is the price of lutetium?
Lutetium costs 42 USD for a 5 gram ingot.
What is the Bohr model for lutetium?
If you think to the electron configuration of lutetium this is: [Xe]4f14.5d1.6s2.
How many valence electrons are in lutetium?
There are 2 valence electrons in lutetium. It belongs to group 3 of the periodic table, so it has 2 electrons in its outermost shell.
Is lutetium a solid liquid or gas?
Lutetium is a solid at room temperature. It is a rare earth metal that has a silver-white color and is a relatively dense and stable element.
What is the element with104 neutrons?
Lutetium (Lu) has 104 neutrons To find this number for any element, take the atomic number (lutetium is 71 on the periodic table) and the mass number of the element and subtract to find neutrons. The atomic number represents the number of Protons and electrons in an atom, the mass number can be found by rounding the atomic mass. If you subtract the # of protons from the total it will tell you how many particles , or neutrons, are left in the nucleus of the atom.. The atomic mass of Lu is 174.967 amu Therefore 175 (total particles) -71 (proton particles)= 104 Neutron particles.
