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 is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
Every element has its own atomic number the atomic number is the number of what?
the atomic number represents the number of protons in an elements atoms
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
Atomic number of an atom is equal to the number of?
The atomic number of an atom is the number of protons in that atom. For example, the atomic number of hydrogen is 1 because one hydrogen atom have one proton.
The atomic number of an element is determined by the number of?
The atomic number of an element is determined by the number of protons within it's nucleus.
What is the mass number of methane?
Methane is a chemical compound so it does not have an atomic number, but it does have a molecular formula, which is written as CH4.Methane is composed of one carbon atom (atomic number 6) bonded to four hydrogen atoms (atomic number 1). The molar mass of methane is:4 * 1.0079 + 12.011 = 16.0426 grams per mole.
What is the atomic weight of one mole CH4?
4
In CH4 - is 4 a catalyst?
CH4 is the chemical formula of methane; 4 is the number of carbon atoms.
How much mass does a ch4 molecule have?
Add atomic masses of each atom.So answer is about 16
What is the formula weight of methane CH4?
Add atomic mass of each atom.So it is about 16
What is the weight percent of carbon in CH4?
Carbon has a atomic mass of 12.So its percentage is 75%
Number ammonia molecules in 3.75g of CH4?
None. CH4 is methane. NH3 is ammonia. You have made some kind of error.
What is the number of protons in the neucleus called?
the answer is that it is called a atomic number.
Atomic number in the atomic nucleus?
The atomic number is equal to the number of the protons in the atomic nucleus.
The number of neutrons in an atom can be found by subtracting the atomic number from the?
Atomic weight in atomic mass units = the number of protons + the number of neutrons. The number of protons is your atomic number. Subtract that from the atomic weight for the number of neutrons.
This element has an atomic number that is double the atomic number of silicon?
this elemnt has an atomic number that is double the atomic number of silicon?
What is the number of neutrons in an atomic number?
Subtract the atomic number from the atomic weight.
