Mass numberof anything - metal or non metal is, (total number of protons) + (total number of neutrons)
For example, mass number of carbon is 12 (6 protons + 6 neutrons)
Mass number of a metal,say- magnesium is 24(12 protons + 12 neutrons)

Why are copper nitrate and sulfur nitrate the same colour?
Well for one reason is on the periodic table the transition metals such as copper, and the non metals such as sulfur are in the same family but not the same group their atomic number is slightly different due to the number of protons, and neutrons. Their atomic mass is quite similar to this is why they are virtually identical.
In order to calculate the number of neutrons you must subtract the from the?
Number of neutrons = Mass number - atomic number
What is Ba atomic number?
Atomic Number is 47; Atomic Mass is 137.3; Element Name is Barium; Classified as the Alkaline Earth Metals.
The mass number of an element is the number of?
Mass number is the atomic mass of a particular isotope (apex chem 5.3)
Can you use the mass number of an element to determine the number of electrons in an atom?
Mass number = number of protons + number of neutrons Number of electrons = number of protons = mass number of an isotope - number of neutrons
What mass of sodium metals contains the same number of atoms as 12.00g of carbon?
i dont know the answer
How does the periodic table help us understand an elements properties?
hi there It depends really, there are many elements on the periodic table that are split into groups, 8 groups to be exact (0-7), which consist of reactive metals, transition metals, other metals, non-metals and noble gases. on every element there is the mass number which is the total number of protons and neutrons and then there is the atomic number which is the number of protons and its the same as the number of electrons. hope this helps :)
Why is lithium more lighter than other alkali metals?
So it has the lowest atom number, the lowest mass as well
What is the largest element in the alkali metal?
No. In fact lithium, one of the alkali metals, is the lightest metal. In terms of molecular mass the heaviest metals are the actinides. In terms of density the densest metals are osmium and iridium.
What is a metal that has a mass of 68g?
Without restricting the volume, any number of properly sized (volume) metals can weigh 68 grams.
What is the least densest of all common metals?
mass
Which hand side are metals on a periodic table?
left mostly. although there is 1 nonmetal, the metals are located on the far left side. there are also transition metals which are located in the center. but there are some semimetals located on the right side. there is no set place for all the metals do to that the periodic table is organzied by atomic mass and number of protons.
Metals having atomic mass 50-100?
Find the names of 20 metals having atomic mass less than 50 their symbol, physical state
Is metal are matter?
Anything that has mass and volume is matter. Metals have mass and volume, therefore they are matter.
How is periodic table divided?
1 is least massive leading to the manmade elements in the 100's which are most massive, and also by gasses, non-metals, metaloids and metals'
What are the number of metals and non metals present among the 116 elements?
About 75 metals.
What element hase an atomic mas of 106.42?
Element Palladium has an atomic mass of 106.42 .It has atomic number 46.It belongs to the group of transition metals.
