You add up the mass of the protons, neutrons, and electrons. Protons and Neutrons having an Atomic Mass of 1, and electrons having an atomic mass of roughly 1/1800.
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
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.
The nucleus of an atom represents most of an atom's mass.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
You can "figure out" by checking the periodic table :D
The mass.If you also know the element number you can figure out the number of neutrons (provided its an isotopic mass rather than an average 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.
Atomic mass is the number of protons + the number of neutrons in the nucleus of an atom. On the periodic table, the average atomic mass of an element will the be number at the bottom of each box.
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.
The nucleus of an atom represents most of an atom's mass.
Adding a neutron increases the atom's mass by about 1 AMU assuming it remains stable.
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
Yes, the mass of an iron atom is different from the mass of a copper atom. The mass of an iron atom is approximately 56 atomic mass units, while the mass of a copper atom is approximately 63.5 atomic mass units. Therefore, there is a difference of about 7.5 atomic mass units between the two.
99.9% of the mass of an atom is located in the nucleus

The atomic mass of an atom is the combined mass of the protons and neutrons in the nucleus.
