What is the number determined by the average mass of naturally occurring atoms of a given element?
I believe it is a mole
How do yo find an atoms mass number?
The mass number of an atom is determined by adding together the number of protons and neutrons in the nucleus of the atom. This information can be found on the periodic table of elements where the mass number is typically listed underneath the symbol of the element.
What is an atoms mass number?
neutrons + protons = mass number
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.
Atomic mass is determined by the number of protons plus the number of?
neutrons in an atom's nucleus. It is measured in atomic mass units (amu) and provides the total mass of an atom. The atomic mass is approximately equal to the sum of the protons and neutrons in the nucleus, as the mass of electrons is negligible.
How can an atoms number of neutrons be determined?
Mass number-Atomic Number= Number of neutrons
Why must the number of atoms in a substance be determined using mass and not by counting?
Atoms are too small to count and there are too many of them.
What is the number determined by the average mass of naturally occurring atoms of a given element?
I believe it is a mole
What is the element that has a mass of 55 and contains 30 neutrons in its atoms?
The element with a mass of 55 and 30 neutrons in its atoms is zinc (Zn). This can be determined by subtracting the number of neutrons from the atomic mass of the element.
What determines the atomic number of a substance?
The atomic number is the number of protons in the nucleus of an atom, while the atomic mass is the total mass of the nucleus (both protons and neutrons)
How do you calculate the atomic weight of fluorine if the mass of 8.46.10 to the 24 atoms of fluorine is 266.889?
Atomic weight of fluorine = 6,022 141 78.1023 (Avogadro number) . 266,889 (the mass of atoms)/8,46.1024 (the number of atoms). The IUPAC 2005 atomic weight of fluorine is 18,998 403 2(5).
How do yo find an atoms mass number?
The mass number of an atom is determined by adding together the number of protons and neutrons in the nucleus of the atom. This information can be found on the periodic table of elements where the mass number is typically listed underneath the symbol of the element.
Which has more atoms 12 grams of carbon or 32 grams of carbon?
Both samples contain the same number of carbon atoms because the number of atoms in a sample is determined by Avogadro's number (6.022 x 10^23) and not by the mass of the sample itself.
What is an atoms mass number?
neutrons + protons = mass number
Does gas have definite mass?
Yes, gas has mass. The mass of a gas is determined by the number of gas particles present and the type of gas molecules. The mass of gas can be measured using a balance or by determining the mass of the container before and after the gas is added.
What is the origin of Avogadro's number and how is it determined?
Avogadro's number is named after Italian scientist Amedeo Avogadro, who proposed in 1811 that equal volumes of gases at the same temperature and pressure contain the same number of molecules. Avogadro's number is determined experimentally by measuring the mass of a known number of atoms or molecules and then calculating the number of particles in a mole based on this mass.
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.
