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.
How do you find the number of neutrons from the mass number?
Atomic mass is the number of protons in an atom mass number is the number of protons plus neutrons in an atom the number of neutrons would equal the mass number minus the atomic number.
What is the atomic number and mass of boron?
Atomic Number = 5 Atomic Mass = 10.811
What is the mass and atomic number of silver?
Silver is a meta element. Atomic mass of it is 107. Atomic number of it is 47.
How can you determine the number of neutrons in an atom if its mass number and its atomic number are known?
It is impossible to determine the number of neutrons from the mass number and atomic mass, since the two are essentially same value. However, with the atomic number and the mass number, one can calculate the number of neutrons by subtracting the atomic number from the mass number.

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 is the atomic mass number of krypton?
83.98 amu is the Atomic Mass, 36 is the atomic number.
Is it true that The atomic mass is equal to the atomic number?
No, the atomic mass is not equal to the atomic number. The atomic number represents the number of protons in an atom's nucleus, while the atomic mass is the sum of protons and neutrons in the nucleus. The atomic mass can differ from the atomic number, especially due to the presence of neutrons.
What is the difference between the atomic number mass number and atomic mass?
We can find Atomic Mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
What do you do with an atomic number and an atomic mass?
The atomic number is the number of a chemical element in the periodic table of Mendeleev; the atomic number is equal to the number of protons and electrons. The atomic mass is the mass of an atom expressed in relative atomic mass units.
Can you use the atomic number and atomic mass to calculate the number of each subatomic particle?
atomic number = number of protons = number of electrons atomic mass = mass of protons + mass of neutrons
What is atomic mass and atomic number for radium?
The atomic number is 88 and the atomic mass is 226
How much is the atomic mass and atomic number for corbon?
Carbon is a chemical element with an atomic number of 6 and an atomic mass of about 12.011 atomic mass units.
What is the relationship btw atomic mass and atomic mass number?
We can find atomic mass and mass number in chemical elements. Atomic mass is about weight of the atom. Mass number is about total of neutrons and protons.
How do you know the number of neutrons an atom has?
You can find the number of neutrons in an atom by subtracting the atomic number (number of protons) from the atomic mass number (rounded atomic weight). The atomic mass number represents the sum of protons and neutrons in the nucleus.
Difference between atomic and mass number?
Atomic number shows the number of protons in an element and the mass number shows the number of protons+neutrons In an electrically neutral atom, atomic number is also the number of electrons .
