The mass number
mass number
Ununhexium is a synthetic element with the atomic number 116. Since atomic number represents the number of protons in an atom, ununhexium would have 116 protons. The number of neutrons can vary depending on the isotope of ununhexium.
Aluminum has 13 protons and approximately 14 neutrons.
Mercury has 80 protons; the number of neutrons is between 116 and 124, depending on the isotope.
no. of protons+no. of nuetrons in an atom is known as mass no. of that atom.while no . of protons present in an atom is called its atomic no.thus, in 1st condition we consider both, no. of protons as well as no. of nuetrons and in the 2nd condition we just consider no. of protons.
mass number = protons + nuetrons
mass number = protons + nuetrons
mass number
atomic number is the number of protons. the sum of protons and neutrons is known as mass number
Ununhexium is a synthetic element with the atomic number 116. Since atomic number represents the number of protons in an atom, ununhexium would have 116 protons. The number of neutrons can vary depending on the isotope of ununhexium.
12,13, and 26
Mass number will help you. Mass number is the total of neutrons and protons.
Aluminum has 13 protons and approximately 14 neutrons.
The Mass Number.
An element can be identified by the number of protons in the nucleus of its atoms.
since there are 22 protons there has to be 22 nuetrons since there are 22 protons there has to be 22 nuetrons
no. -------------- In atoms, only the Protons count as atomic number The neutrons and the protons together is as the atomic mass
