The element uranium (U) has 92 protons in its nucleus. That's where its atomic number comes from. When we see an isotope of an element written in "standard" form, the element name or symbol will be followed by the Atomic Mass (atomic weight) of the isotope. This number is basically the number of protons and neutrons (called nucleons when they are in an atomic nucleus) in an atom. In this case, we have U-235 and U-238. In the first case, 235 - 92 = 143, so U-235 has 143 neutrons. In the second case, 238 - 92 = 146, so U-238 has 146 neutrons. See the Related Questions below for how to find the number of neutrons in any atom.
Uranium-235 has 143 neutrons, and uranium-238 has 146 neutrons.
The neutral atom of uranium (any isotope) has 92 electrons.
92 protons for all isotopes of uranium because the atomic number is 92.
The isotope 238U has 92 protons; all the isotopes of uranium have 92 protons.
Protons = 92 Neutrons 238-92 = 146
No, not all nuclei contain both protons and neutrons. Hydrogen-1, the simplest atom, has only one proton in its nucleus and no neutrons. Other elements can have different numbers of protons and neutrons in their nuclei.
There are 18, 20 or 22 neutrons.
Indium has 66 neutrons.
18 protons and 18, 20 or 22 neutrons.
how many protons neutrons and electrons does lithium have? 3 protons 4 neutrons 3 electronsA lithium atom has three protons and so three electrons. The number of neutrons depends on the isotope, with the two naturally occurring stable isotopes of lithium, 6Li and 7Li, having 3 and 4 neutrons respectively.3: In any neutral atom, there are the same number of electrons as of protons, and the number of protons is the same as the atomic number, which for lithium is 3.
143 & 146
It depends on the isotope. Zn-64 and Zn-68 isotopes have 34 and 38 neutrons respectively.
23 electrons, 26 protons, 30 neutrons.
18.5 neutrons Neutrons can not be a fraction. Must be a whole number. Chlorine has 18 neutrons
In a nitrogen-14 atom, there are 7 neutrons, where the isotopes with mass numbers with 13 and 15, have 6 and 8 neutrons respectively.
Two stable isotopes: Cu(63) 69% occurrance and Cu(65) 31%They have (63-29)= 34 and (65-29)= 36 neutrons respectively.
There is one electron in every hydrogen atom. They have 1, 2 and 3 neutrons respectively in protium, deuterium and tritium.
Every nitrogen atom has 7 electrons. There are 7, 8 and 9 neutrons in nitrogen-14, nitrogen-15 and nitrogen-16 isotopes respectively.
An oxygen always has 8 protons and normally has 8 neutrons, but a very small minority of oxygen atoms are isotopes of oxygen-17 or oxygen-18 which contain 9 or 10 neutrons respectively.
An atom of neon consists of 10 protons, 10 neutrons and 10 electrons (atomic number = 10; atomic mass = 20)
Iodine has 53 protons. Iodine 127 has 74 neutrons. With a negative charge, it would have an extra electron, meaning it would have 54 electrons.
There are two main isotopes of chlorine. Every chlorine atom has 17 electrons where there are 18 and 20 neutrons in chlorine-35 and chlorine-37 respectively.
