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.
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.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
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.
Can the mass number be used to determine the number of electrons in an atom?
No, the mass number (number of protons and neutrons) cannot be used to determine the number of electrons in an atom. The number of electrons in an atom is determined by the number of protons in the nucleus, which is the atomic number. Electrons are equal in number to protons in a neutral atom.
Can the mass number of an element be used to determine the number of electrons in an atom?
No, the mass number of an element represents the total number of protons and neutrons in the nucleus, but it does not provide information about the number of electrons. The number of electrons in a neutral atom is equal to the number of protons in the nucleus.
What characteristic of an atom is NOT used to determine the number of neutrons in an atom?
The characteristic of an atom that is not used to determine the number of neutrons is its atomic number. The atomic number indicates the number of protons in an atom, while the number of neutrons is derived from the difference between the atomic mass (which is the total number of protons and neutrons) and the atomic number. Therefore, only the atomic mass and the atomic number are needed to calculate the number of neutrons.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
What does the mass number in helium represent?
The mass number in helium represents the total number of protons and neutrons in the nucleus of a helium atom. It is used to determine the mass of the atom and differentiate between different isotopes of helium.
What is used to find the mass of an atom?
The mass of an atom is obtained dividing the atomic weight of an isotope by the Avogadro number.
How do scientists determine the atomic mass of an atom?
Scientists determine the atomic mass of an atom by averaging the masses of all the isotopes of that element, weighted by their abundances. This information can be obtained from mass spectrometry data and is used to calculate the weighted average mass. The atomic mass is typically reported in atomic mass units (amu).
What is a specific element of how to determine the number of protonsneutronsand electrons in an atom?
To determine the number of protons, neutrons, and electrons in an atom, you first need to know the atomic number, which represents the number of protons and, in a neutral atom, also the number of electrons. The mass number, which is the sum of protons and neutrons, can be used to calculate the number of neutrons by subtracting the atomic number from the mass number. For example, if an atom has an atomic number of 6 (carbon) and a mass number of 12, it has 6 protons, 6 electrons, and 6 neutrons (12 - 6 = 6).
