all atoms have different masses
Mass of an atom is due to protons and neutrons present in an atom and number of proton is something that distinguish between atoms, therefore mass of hydrogen is different to the mass number of oxygen, hydrogen's mass is 1 as it has only 1 proton and no neutrons, and oxygen mass's is 16 as it has 8 protons and 8 neutrons.
No, a hydrogen atom with a mass of 3 is not an isotope of hydrogen. Hydrogen isotopes include protium (mass 1), deuterium (mass 2), and tritium (mass 3).
16
An atom of hydrogen has one proton and one electron, with a mass of approximately 1 atomic mass unit. An atom of carbon has 6 protons, 6 neutrons, and 6 electrons, with a mass of approximately 12 atomic mass units.
RFM stands for Relative Formula Mass, and is calculated by adding up the atomic masses of all the elements in the chemical formula of a compound. In the case of water (H2O), the RFM would be calculated as: (2 atoms of hydrogen x atomic mass of hydrogen) + (1 atom of oxygen x atomic mass of oxygen). The atomic masses of hydrogen and oxygen are approximately 1 and 16 respectively, so the RFM of H2O would be approximately 18.
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.
an oxygen and a hydrogen atom do not weight the same
The atomic weight (not mass) of hydrogen is: [1,00784; 1,00811]; the conventional value is 1,008. The atomic weight (not mass) of oxygen is: [15,99903; 15,99977]; the conventional value is 15,999.
By number of atoms it has more hydrogen, by mass it has more oxygen. Each water molecule contains two hydrogen atoms and one oxygen atom. However, a typical oxygen atom has about 16 times the mass of a typical hydrogen atom.
No, it is inverse.
The molecular mass of water (H2O) is 18, which means the total mass of one oxygen atom and two hydrogen atoms is 18. Since the atomic mass number of hydrogen is 1, the atomic mass of oxygen can be calculated as 16 (18 - 2).
It's also 16 amu, ignoring the slight possibility of a different isotope.
Hydrogen is the lightest of all elements, having atoms that are only a fraction of the mass of all other elements. For example, an oxygen atom has about 16 times the mass of a hydrogen atom. So while a water molecule contains 2 hydrogen atoms and 1 oxygen atom (and water makes up most of the human body), the single oxygen atom accounts for most of the mass of the molecule.
The masses of hydrogen, oxygen, and all the elements are on the periodic table. The mass for hydrogen is 1.01, and that for oxygen, 16.0, so a single oxygen atom weighs as much as 16 hydrogen atoms.
No all oxygen atoms do not have the same mass as you can get isotypes of the same element which are still called the same except that they can have more or less neutrons than the standard model this is why the weight is refered to as an average mass
Hydrogen atoms are the smallest known elements, and therefore smaller than oxygen atoms (according to atomic weight and atomic mass).
No, an oxygen atom does not have twice the mass of a sulfur atom. An oxygen atom has a mass of approximately 16 atomic mass units (amu), while a sulfur atom has a mass of approximately 32 amu. Therefore, a sulfur atom has twice the mass of an oxygen atom.
That depends on the atom. An atom of oxygen is 16 times heavier than a hydrogen atom (the lightest atom). Uranium atoms are over 200 times heavier than hydrogen. Regardless of what type of atom it is, a single atom won't weigh very much. well i assure you it is small and light specify the question more
