Is an oxygen atom have twice the mass of a sulphur atom?
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.
What information does the percent composition of an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule
Subatomic particle that contributes mass and a positive electrical charge to an atom?
The sub atomic particles to an atom are the proton (p), neutron (n). The p and n both contribute to atomic mass. The positive charge comes from the p and outside the atom in orbit is/are the electron with negligible mass, but negative charge.
What does adding A neutron to an atom's do to the atom's mass?
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
What is the mass of a carbon atom?
The mass of a carbon atom is approximately 12 atomic mass units.
What information does the percent composition in an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule
What subatomic particle or particles contributes the most to the mass of the atom?
These particles are protons and neutrons.
What contributes to an atom's atomic number and to its mass number?
An atom's atomic number is determined by the number of protons in its nucleus, which are positively charged. The mass number is the sum of the protons and neutrons in the nucleus, as neutrons contribute to the atom's mass but not its charge.
How can there be 1 proton with a hydrogen atom with a mass?
Though a hydrogen atom typically has one proton, its mass is not solely determined by the proton. The mass of a hydrogen atom comes from the combination of the proton and an electron. The electron contributes a much smaller amount to the overall mass compared to the proton.
What particle of a atom has zero or no charge?
The neutron is the particle of an atom that has zero charge. It is located in the nucleus along with protons and contributes to the overall mass of the atom without affecting its charge.
Is an oxygen atom have twice the mass of a sulphur atom?
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.
What information does the percent composition of an atom in a molecule give?
The relative amount of mass an atom contributes to a molecule
What particle contributes a negligible amount to the atomic mass?
There are a number of particles of particularly low mass. Electrons have much less mass than either protons or neutrons, and so are negligible in calculating the mass of an atom. However, electrons are still much heavier than neutrinos or photons, which are even more negligible in mass.
What represents most of an atom's mass?
The nucleus of an atom represents most of an atom's mass.
The relative atomic mass of an atom can be found by comparing the mass of the atom to the mass of?
The Hydrogen atom. Beware, Hydrogen has an atomic mass based on one proton, as it doesn't have a neutron. So Helium has a mass of four times Hydrogen.
Subatomic particle that contributes mass and a positive electrical charge to an atom?
The sub atomic particles to an atom are the proton (p), neutron (n). The p and n both contribute to atomic mass. The positive charge comes from the p and outside the atom in orbit is/are the electron with negligible mass, but negative charge.
What 2 particles make up most of the atomic mass?
Although not all, per se, the proton and neutron in the nucleus of the atom comprise the vast majority of the mass of an atom. The electron, though not massless, contributes a practically negligible mass to the atom by comparison.The heaviest particle is the neutron. If we assign it a mass of 1.0 mass unit, then the proton is next with a mass of 0.9986 mass units, followed by the lowly electron with a mere 0.0005 mass units.
