ANSWER: There are 95 protons, 148 neutrons, and 95 electrons in ²⁴³Am.

How many neutrons does americium 238 have?

Therefore, it has 92 protons, 92 electrons, and 238 — 92: 146 neutrons. Its symbol is U23892 (or ²³⁸U). The total mass of an atom is called its atomic weight, and is the approximate sum of the masses of its constituent protons, neutrons, and electrons.

How many electrons does 80 Br have?

ANSWER: There are 35 protons, 45 neutrons, and 35 electrons in ⁸⁰Br.

What is the 18th element?

Argon – Element information, properties and uses | Periodic Table.

How many protons and neutrons are in americium?

95

How many protons does fluorine have?

Uranium has an atomic number of 92 which means there are 92 protons and 92 electrons in the atomic structure. U-238 has 146 neutrons in the nucleus, but the number of neutrons can vary from 141 to 146. Because uranium is radioactive, it is constantly emitting particles and changing into other elements.

How many protons are there in Americium?

Therefore, Rn has 222 – 86 = 136 neutrons. Number of electrons and number of protons are equal in a neutral atom. Therefore, Rn has 86 electrons.

How many protons neutrons and electrons are in bromine 81?

So Bromine Br−1 has 35 protons, 36 electrons and 45 neutrons.

How many protons and electrons does BR have?

Explanation: The atomic number for bromine is 35, which means it has 35 protons in its atomic nuclei. A neutral bromine atom would also have 35 electrons. In order for a bromine atom to become a 1− bromide ion, it would have to gain an additional electron.
