atomic Hydrogen is just that: 1 atom of hydrogen (H+). molecular Hydrogen is a molecule, much more stable than atomic Hydrogen (H2). molecular H2 is more abundant than H+ in nature, due to H2 being more stable.


The symbol for atomic hydrogen is H. But hydrogen as a gas molecule consists of two hydrogen atoms, so the formula for molecular hydrogen is H2.


The molecular mass of hydrogen gas is 2. A molecule of hydrogen gas contains two hydrogen atoms covalently bonded. Since each hydrogen atom has an atomic mass of 1 (as we can derive from the Periodic Table of Elements), the molecular mass of hydrogen gas as a molecule is 1 + 1 = 2.


C6H12O6 is the molecular formula for sugar-----------------------------------------------------------------------------H is an atom where H2 is a molecule. But we name both by the same word hydrogen. Just to differentiate we have to name H as mono atomic hydrogen and H2 by the name molecular hydrogen. H would be placed in the periodic table and not H2Same way O is atomic oxygen and O2 as molecular oxygen. So the one given by you ie C6H12O6 is a molecule. This molecule has 6 carbon atoms, 12 hydrogen atoms and 6 oxygen atoms.A single atom is, sometimes, named as mono atomic molecule. What can we do? Such confusing statements are made often. That is human mind's hide and seek game.


Water molecules are composed from hydrogen and oxygen. Their atomic masses are 1 and 16 respectively. The molecular mass of water is 2x1+16=18u.


Salt can't have an atomic weight because it is not an atom : it is a molecule composed of two atoms. The molecular weight of common salt is approx. 58.4 amu


Molecular orbital is related to a molecule; atomic orbital is related to an atom.


Hydrogen molecule is the lightest because of its atomic mass being less than any other molecule .i.e 1amu (atomic mass unit). Hence Hydrogen molecule is lighter than Methane molecule.


The molecular weight is the sum of the atomic weights of all the atoms contained in the molecule.


Molecular formulas can not be determined from information about atomic ratios only. If the ratios stated are atomic ratios, then the empirical formula of the compound is CH2O. If the questioner meant, "A glucose molecule contains 6 carbon atoms, 12 hydrogen atoms, and 6 oxygen atoms ...", the molecular formula is C6H12O6.


(i) By thermal dissociationWhen molecular hydrogen is heated at 5000C,it dissociates into atomic hydrogen.(ii) By electric dischargeAt o.1 mm Hg to 1.00 mm Hg pressure


A water molecule is made of two hydrogen atoms attached to an oxygen atom. Their atomic masses are 1 and 16 respectively. So the molecular mass of water is 2x1+16=18 grams per mole.


The hydrogen peroxide is a molecule, not an atom.


A water molecule has two hydrogen atoms attached to an oxygen atom. Their atomic masses are 1 and 16 respectively. So the molecular mass of water is 16+1x2=18u.


When hydrogen is liberated from a compound in a chemical reaction it invariably forms molecular hydrogen, H2, rather than atomic hydrogen.


Yes, the accumulation of atomic masses of the atoms within a molecule is the molecule's molecular mass.


The density of a gas is proportional to its molecular or atomic weight. Hydrogen has a molecular mass of about 2, while helium has an atomic mass of about 4. Therefore, helium is about twice as dense as hydrogen.


Well first of all a molecule doesn't have an atomic mass it has a molecular mass. It's molecular mass is found by adding up the atomic masses of all the elements that make up the molecule. These atomic masses are found on a periodic table. For example water has a formula of H20. This means it is made of 2 hydrogen atoms and 1 oxygen atom. Hydrogen has an atomic mass of 1 g/mol while oxygen has an atomic mass of 16 g/mol. So the molecular mass of water is 2 x 1g/mol + 1 x 16 g/mol = 18 g/mol


A molecule of butane contains four carbon atoms and ten hydrogen atoms. Their atomic masses are 12 and 1 respectively. Therefore the molecular mass of butane is 4x12+10x1=58u.


Nitrogen has a diatomic molecule (N2).


Atomic mass is the mass of one atom of a particular element. For example, Oxygen has an atomic mass of 16u and Hydrogen has an atomic mass of 1u approximately (The actual value is 1.008 u). Molecular mass on the other hand is the sum of atomic masses of all the atoms present in a molecule. For example, H2O (Water) has a molecular mass of 18u approximately. It is obtained by multiplying the atomic mass of en element by the number of atoms present and then adding up the atomic mass of all the elements, i.e., (2x1) + (1x16) = 18u. We are multiplying 1 by 2 as there are 2 atoms of hydrogen in the molecule.


Since each water molecular contains two hydrogen atoms, the atomic mass of oxygen is 18 - 2 = 16.


Atomic weights refer to ATOMS. Water is a MOLECULE made up of 3 atoms, it therefore does not have an atomic weight, it has a MOLECULAR weight.You calculate the molecular weight by adding up the atomic weight of all the atoms in the molecule.Waster is made up from 1 atom of Oxygen (atomic weight 16) and 2 atoms of Hydrogen (atomic weight 1)16+1+1 = 18The molecular weight of water is therefore 18.-------------------------------------------------------------------------------------The atomic mass of H is 1.008, and the atomic mass of O is 16.So 1.008*2+16=18.016


A molecular formula gives the atomic symbol for each kind of atom in the molecule and the number of such atoms present in one molecule.
