What has 92 protons 92 electrons?
uranium
The atomic number of uranium (see periodic table) is 92, and the mass number of the isotope is given as 238. Therefore, it has 92 protons, 92 electrons, and 238 — 92 : 146 neutrons.
Is a protons a particle?
Proton, stable subatomic particle that has a positive charge equal in magnitude to a unit of electron charge and a rest mass of 1.67262 × 10−27 kg, which is 1,836 times the mass of an electron.
What particle is number 92 on the periodic table?
Uranium, U, is a radioactive metallic element with an atomic number of 92. It was discovered in 1789 by Martin Klaproth and is used as a nuclear fuel. uranium; Uranium, or U, has an atomic number of 92 in the periodic table.
What element has 92 protons 92 electrons and 143 neutrons?
In uranium, all family members will have 92 protons, which makes them uranium. One member could have 92 protons and 143 neutrons. Its name would be uranium-235.
Who discovered uranium-235?
Arthur Jeffrey Dempster
Uranium-235 has a half-life of 703.8 million years. It was discovered in 1935 by Arthur Jeffrey Dempster.
What are protons electrons?
Electrons are a type of subatomic particle with a negative charge. Protons are a type of subatomic particle with a positive charge. Protons are bound together in an atom’s nucleus as a result of the strong nuclear force. The positive charge on a proton is equal in magnitude to the negative charge on an electron.
What are protons neutrons electrons?
Protons and neutrons are in the center of the atom, making up the nucleus. Electrons surround the nucleus. Protons have a positive charge. Electrons have a negative charge. The charge on the proton and electron are exactly the same size but opposite.
What is the symbol of 92?
Uranium Facts – Atomic Number 92 Element Symbol U.
How many protons and neutrons does thorium have?
90
Thorium/Atomic number
Thorium (Th). Diagram of the nuclear composition and electron configuration of an atom of thorium-232 (atomic number: 90), the most stable isotope of this element. The nucleus consists of 90 protons (red) and 142 neutrons (blue).
What element has 92 protons and 235 mass number?
Uranium-235
Uranium-235 has 92 protons.
What elements has 92 electrons?
Uranium
Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure.
How are protons and electrons different from each other?
The negative charge of one electron balances the positive charge of one proton. Both protons and neutrons have a mass of 1, while electrons have almost no mass. The element hydrogen has the simplest atoms, each with just one proton and one electron. The proton forms the nucleus, while the electron orbits around it.
How are protons and neutrons related to the atomic number?
The positively charged protons tend to repel each other, and the neutrons help to hold the nucleus together. The number of protons is the atomic number, and the number of protons plus neutrons is the atomic mass. For hydrogen, the atomic number is 1 because there is one proton and no neutrons.
How many protons and neutrons does silicon have?
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 are the three particles that make up an atom?
2.1 Electrons, Protons, Neutrons, and Atoms All matter, including mineral crystals, is made up of atoms, and all atoms are made up of three main particles: protons, neutrons, and electrons. As summarized in Table 2.1, protons are positively charged, neutrons are uncharged and electrons are negatively charged.
