3 Atoms nucleus is surrounded by negatively charged particles called electrons. Eachhas a nominal mass of 1. Atomic number 12.

April 29 2021 thanh. Thus an atom contains 12 protons and 13. So the mass of hydrogen with one protonand no neutrons in its nucleus has a mass of 1.

Electrons in outermost shellD. An atoms atomic number is best described as the number of. 11 An atoms atomic mass is best described as the mass of A the protons it contains B the neutrons it contains.

An element with a mass number of 11 and an atomic number of 5 has how many neutrons. Atomic mass refers to the sum of number of neutrons and protons Option D present in the nucleus. Mass number Number of protons Number of neutrons 2 We are given.

Isotope 3 H refers to the isotope tritium that con. The atomic mass of an element is defined as the weighted average mass of that elements. It is expressed as a multiple of one-twelfth the mass of the carbon-12 atom 1992646547 1023 gram which is assigned an atomic mass of 12 units.

Mass number 25. Its unit is called the unified atomic mass unit and is denoted by the symbol u. For example while writing the electronic configuration.

According to the new current Quantum atomic model An orbital is a region of space in an atom where the probability of finding electrons is maximum. A mass of 50 grams of one chemical is produced. An atoms atomic mass is best described as the mass ofA.
