the mass of an atom of a chemical element expressed in atomic mass units. It is approximately equivalent to the number of protons and neutrons in the atom (the mass number) or to the average number allowing for the relative abundances of different isotopes.
What else can I help you with?
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
What does the mass number of an atom represent?
The mass number of an atom represents the total number of protons and neutrons in the atom's nucleus. It is used to determine the atom's mass, which is important for understanding its properties and behavior in chemical reactions.
What makes an atoms mass number?
An atom's mass number is determined by the sum of its protons and neutrons. Protons have a positive charge and determine the element's identity, while neutrons help stabilize the nucleus and contribute to the atom's mass.
How can you determine the approximate mass of an atom in atomic mass units?
You can determine the approximate mass of an atom in atomic mass units by summing the number of protons and neutrons in the nucleus of the atom. The mass of a proton and neutron is approximately 1 atomic mass unit (amu), so the total mass of the atom would be the number of protons + number of neutrons in the nucleus.
How do you calculate mass of berylium atom?
The mass of a beryllium atom can be calculated by adding the total number of protons and neutrons in the atom, then multiplying by the mass of each particle. Beryllium has 4 protons and 5 or 6 neutrons, depending on the isotope (Be-9 or Be-10). The mass of a proton is approximately 1.007 atomic mass units (amu) and the mass of a neutron is approximately 1.008 amu. By adding these values together, you can determine the mass of a beryllium atom.
Which of the following particles is used to determine the mass of an atom?
Mass of an atom is determined by the no. of protons+ no. of neutrons in the atom.
How do you determine the atom the atomic mass of an atom?
Proton + Nuetron = Atomic Mass
How do you determine an atom's mass number?
mass number= no. of protons + no. of neutron
What determine the mass and an atom?
Protons, neutrons and electrons
What determine the atom mass?
Essentially an atom's mass is determined by its number of protons and neutrons, as mass of electrons is so minuscule relative the nucleus.
What does the mass number determine?
The Number Of Protons & Neutrons In An Atom.
How do you determine neutrons in an atom of sodium-20?
the atomic mass
What is counted in an atom to determine mass number?
The mass number of an atom is determined by counting the total number of protons and neutrons in its nucleus. Electrons, which are much lighter than protons and neutrons, are not included in the mass number calculation.
What particule is used to determine the mass of an atom?
Protons, neutrons and electrons
Mass number used to calculate the number of?
The mass number is used to calculate the number of nucleons in an atom. It represents the sum of protons and neutrons in the nucleus of an atom. By knowing the mass number, one can determine the approximate atomic mass of the atom.
