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 you find the mass number of an atom?
To find the mass number of an atom, you add together the number of protons and neutrons in the nucleus of the atom. The atomic mass listed in the periodic table is the weighted average of the mass numbers of all isotopes of that element.
What Used to find the number of neutrons?
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
How do you find relative atomic mas?
Relative atomic mass is determined by comparing the mass of an atom to one-twelfth of the mass of a carbon-12 atom, which is defined as exactly 12 atomic mass units (amu). To find it, you can use a mass spectrometer to measure the isotopic masses and their relative abundances, then calculate a weighted average based on these values. The formula used is: relative atomic mass = (isotopic mass × relative abundance) / total relative abundance for all isotopes. This gives a value that reflects the average mass of an atom of an element as found in nature.
What is the difference in mass of Na ion and Na atom?
The difference in mass between a sodium atom and a sodium ion (supposing Na+) is 9.10938188 × 10-31kg (the mass of an electron). This is due to the sodium atom losing an electron to form an ion. In order to attain the mass of a single sodium atom you need to divide the molar massn (mass number) of sodium by avogadro's number. You can then find the mass of the ion by subtracting the mass of an electron from the mass of a sodium atom.
What is the unit of measurement used to find the mass of an atom?
Ask your science teacher

What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
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.
What Used to find the number of neutrons?
To find the number of neutrons in an atom, subtract the atomic number (number of protons) from the atomic mass number. Neutrons are uncharged particles found in the nucleus of an atom and their number can vary for a given element based on isotopes.
What is the number of an atom with 5 protons and 7 neutrons?
To the find the mass number of an atom you add the protons and neutrons. Meaning that the mass number of this atom is 12.
What does the mass number of an atom help you find?
it helps you find where the nucleus is located
Why it is not possible to find the absolute mass of an atom?
It is the smallest particle
What unit is used to measure the mass of an atom?
mole
How many electrons does an atom has?
It depends on the atom you are reffering to, but to find the electrons take away the number of protons from the mass number of the atom.
One-twelfth the mass of a carbon-12 atom is used to define?
Atomic mass.
