1. use a calculator, you take the atomic number, divide it by the neutron number. 2. then times the electron number by 100
3. and add the 2 numbers together.
4. now divide by 8

∙ 10y agoEAN is calculated by EAN = Z-X+Y
where
Z= THE ATOMIC NUMBER OF THE METAL
x= NUMBER OF ELECTRONS LOST DURING THE FORMATION OF METAL ION
Y= NUMBER OF ELECTRONS DONATED BY THE LIGANDS

What does the relative atomic mass of an element tell us about the relative abundance of an isotope?
None. The relative abundance of isotopes is used to calculate the Average Mass (by multiplying the Atomic Mass of the isotopes by their relative abundancies and adding the products together) while the Atomic Mass is simply the number of protons plus the number of neutrons.
What is the atomic number of CH4?
CH4 is the compound methane. It does NOT have an atomic number. However it has a Relative Molecular Mass (Mr). To calculate its Mr ;- First refer to the Periodic Table for the Atomic Masses of each element present. We have in CH4 ;- 1 x C = 1 x 12 = 12 4 x H = 4 x 1 = 4 12 + 4 = 16 This is the Mr( Relative Molecular Mass ) of methane ; NOT atomic mass.
What do compounds make up?
A compound is a substance formed from two or more elements chemically united in a fixed proportion; a mixture Example: a compound of hydrogen and oxygen resources: a oxford dicitonary
Explain why most carbon compounds are classified as organic compounds?
Organic compounds are compounds necessary to life, and most macromolecules necessary to life contain carbon.
What is the overall charge of most compounds?
Compounds can be charged by different methods. But naturally most of the compounds are uncharged. So the overall charge of most compounds is neutral.
How you calculate the relative atomic weight of uranium?
The atomic weight of an element is derived from the atomic masses of the isotopes of this element and from the percentage of these isotopes. The correct terms are: - atomic weight for elements - atomic mass for an isotope
What is the atomic mass of the compounds CaO?
the atomic mass of the compounds cao is 56
Average atomic mass of copper is 63.5 amu It exists as two isotopes and Calculate the percentage and ratio of copper isotopes?
Let percentage of = xPercentage of = 100 -xFrom above, average atomic mass= amuBut given average atomic mass = 63.5 amuTherefore,Percentage = 75Percentage of = 100 -75 =25Ratio of and = 75:25=3:1source : www.examville.com
Calculate the percentage by the mass of each element in the following compounds:(g) ethanedioic acid,(COOH)2(h)ethanoic acid, CH3COOH(i) lead nitrate, Pb(NO3)2(j) potassium hydrogencarbonate,KHCO3?
(Atomic masses : C=12u;H=1u;O=16u)
Does the Atomic structures refers to the building of compounds?
No because they are asking about compounds not elements.
How do you calculate the atomic mass of carbon?
The same way you calculate the atomic mass of other elements.
How to calculate neutron?
Atomic mass - Atomic number
What is atomic number of copper sulphate?
"Atomic number" is an expression for chemical elements, not for compounds.

How do you calculate the atomic mass of bromine?
To calculate the atomic mass of any element, add the no. of protons and neutrons. There sum will be the atomic mass. The mass of electrons is not counted towards the atomic mass.
What is atomic number of mercury tetra thiocynatecobalt 2?
Only elements have atomic numbers, not compounds.
