What determines an element's mass?
the mass of protons + the mass of neutrons = mass of the element
An element's atomic mass number is?
It is about neutrons and protons. The total of neutrons and protons.
What is the mass number of an atom with 11 protons 11 electrons 12 neutrons?
Sodium is a metal element. Mass number of it is 23.
The mass number of an atom indicates the number of what?
The mass number is the sum of protons + neutrons.
What element has a mass number of 56 with 36 neutrons?
A mass number is the sum of numbers of protons and neutrons in an atom. Therefore, an element with a mass number of 65 and 36 neutrons contains (65 - 36) or 29 protons and is therefore an atom of copper.
The mass number of an element is equal to the total number of?
The mass number is the average atomic mass of all the isotopes that are found in nature.
How is the nucleus related to the periodic table?
The nucleus contains the protons and neutrons. The number of protons determines the atomic number of the element and the number of protons and the number of neutrons together determine the atomic mass.
What is an element's atomic mass?
protons + neutrons
What is the mass numberfor an atom with 5 electrons 5 protons and 5 neutrons?
It is the boron element. It contains similar numbers of electrons and protons.
What is the atomic symbol for an element that has 10 neutrons and a mass number of 19?
It contains 10 protons and 10 electrons (no. of protons =no. of electrons in ground state) Number of neutrons=Mass number of element- number of protons =19-10 =9
What is the approximate mass of an atom that contains 10 protons and 11 neutrons?
The approximate mass of an atom that contains 10 protons and 11 neutrons is 21.
What is the sum of protons and neutrons known as an element?
Sum of protons and neutrons is the Mass number of the element. The number of protons is equal to the number of electrons. Neutrons and protons are sub atomic particles.
