Mass of electron compared to proton?
Mass of electron is about 1837 times less than the mass of proton
Are two atoms of different elements because they have close but different masses?
An element is made up of only one type of atom. Atoms are only different from each other due to their atomic number - which is the number of protons. Different elements may have different relative atomic masses, but it is the differing number of protons in each atom that determines which element it is.
How relative atomic mass of an atom can be determined?
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
Why is the mass numbers of isotopes exact whole numbers but the relative masses of most Atoms are not exact whole numbers?
Relative atomic massisthe ratio of the averagemassofatomsof anelementto 1/12 of the mass of an atom ofcarbon-12. The mass number of an isotope is the sum of protons and neutrons in the atoms of the isotope.
What is an isotope and why are atomic masses usually in decimal form?
An isotope is a variant of the atom with the same number of protons but more or fewer neutrons. The atomic mass is an average of the isotopes of the element. The average is weighted according to the relative abundance of such isotopes.
Which subatomic particles have similar masses?
Neutrons and protons have mass 1 (relative to proton, given the value of 1).Electrons have mass 1/1840 (relative to proton, given the value of 1).:)Protons and neutrons have almost the same mass.
Mass of electron compared to proton?
Mass of electron is about 1837 times less than the mass of proton

Different elements may have different relative atomic masses, but it is the differing number of protons in each atom that determines which element it is.
How big is a photon and what is its size compared to other particles?
A photon is a fundamental particle of light with no size or mass. It is much smaller than other particles, such as electrons and protons, which have measurable sizes and masses.
Why do chemists use relative masses of atoms compared to a reference isotope rather than absolute masses in their calculations?
Chemists use relative masses of atoms compared to a reference isotope because it allows for easier comparison and calculation of chemical reactions. Absolute masses can vary, but relative masses provide a consistent point of reference for analysis.
How relative atomic mass of an atom can be determined?
The relative atomic mass of an atom can be determined by averaging the masses of its isotopes based on their abundance in nature. This value is reported relative to the mass of a carbon-12 atom, which has been assigned a relative atomic mass of exactly 12.ø
What occurs for two atoms to be isotopes of each other?
Two atoms are isotopes of each other when they have the same number of protons but different numbers of neutrons. This results in the atoms having the same chemical properties but different atomic masses.
What mapmaking method would minimize distortion of land masses on a world map?
A mapmaking method that minimizes distortion of land masses is the Equal Area projection, which preserves accurate relative sizes of land areas. Examples include the Mollweide and Goode's Homolosine projections.
How do the masses of one electron compare to the masses of protons and neutrons?
mass of electron = 1/1836 mass of proton (or neutron)
What are the masses of each subatomic particle?
protons and neutrons are about 1 amu
What are atoms of an element that make different atomic masses?
protons and neutrons
What The atomic mass of an atom equals the sum of the masses of the?
Protons and neutrons.
