What does the term mean atomic number mass number?
The atomic number represents the number of protons in an atom's nucleus, determining the element's identity. The mass number is the sum of the protons and neutrons in an atom's nucleus, giving the atom its mass.
What does the atomic mass and number depend on?
As electrons have almost negligeable mass when compared to a proton, the mass of an atom mostly depends on the number of protons and neutrons in its nucleus. The mass of an electron is almost 1800 times smaller than the mass of a proton or neutron so in most calculations it can be safely assumed to be zero. In other words the mass of an atom depends on its atomic number.
What do the superscript and subscript mean in the notation 40 K represent 19?
The subscript (19) indicates that this atom has 19 protons (as well as 19 electrons). The supersript (40) denotes that it has 40 protons and neutrons, hence we can infer that it has 21 neutrons.
Does atomic number and atomic mass mean the same thing?
atomic mass and mass number are differernt because atomic mass mean mass of whole atom which mean mass of proton,neutron and electron while mass number is number of proton and neutron only.zahid ullah paf college risalpur
What does one determine an atoms atomic mass?
If you mean "how does one determine an atoms atomic mass?", then the answer would be to find a periodic table of elements where the whole numbers indicate atomic number and the other indicating atomic mass. Atomic number is generally described as the number of protons in a naturally occurring atom of a given element, and the atomic mass is the number of protons + number of neutrons in an atom.
What does the term mean atomic number mass number?
The atomic number represents the number of protons in an atom's nucleus, determining the element's identity. The mass number is the sum of the protons and neutrons in an atom's nucleus, giving the atom its mass.
What do atomic number and atomic mass mean?
The atomic number is equal to either the number of electrons or the protons of a particular atom. The atomic mass in a.m.u. is equal to the sum of protons and neutrons in an atom.
What deos atom mean?
atomic mass is the number of protons in the nucleus of an atom.It can also be equal to the number of electrons in a neutral atom
What do you mean by the atomic mass of an atom?
That's 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.
How neutrons does bromine have?
Bromine has the atomic number 35, which means there are 35 protons in the nucleus of an atom of bromine.The mass number (also known as the atomic mass number) of an element is the sum of the protons and neutrons in the nucleus.Bromine's mass number is 80, so there must be 35 protons and 45 neutrons in an atom of bromine.Sorry we do not know what you mean by "newtrons" or "deos".
What does the letter A symbolizes in physics?
In Nuclear Physics, A stands for atomic mass number. Atomic number is the number of protons and neutrons present in the nucleus of a given atom. Basically it tells us about the mass of the atom, as nucleons are the only sub-atomic particles which have mass. Nucleons mean neutrons and protons.
What does the equation N equals A-Z mean?
N represents the number of neutrons in an atom, A represents the atom's mass number and Z is the atoms proton number. This makes sense because it shows that the mass number of an atom is the number of protons added to the number of neutrons in the nucleus.
What does the atomic mass and number depend on?

What its a difference between atomic number mass number and atomic weight?
atomic number is the number of protons in an atom (same for all isotopes of that element)atomic mass number is total of protons + neutrons in one particular isotope nucleus of that element.atomic weight is (symbol: Ar) is a dimensionless physical quantity, being the ratio of the average mass of atoms of an element (from a given source) to 1/12 of the mass of an atom of carbon-12 (known as the unified atomic mass unit). It is the mean weight of all natural occurring isotopes of that particular element.Example: Carbonatom number 6mass number 10, 11, 12, 13, 14, of which only 12, 13 (and variable 14) are naturally occurring isotopes (resp. 98.89% and 1,11%)atom weight (relatve mass) 12.0107(8) a.m.u.
How many nucleons does an oxygen with a mass number of 17 and an atomic number of 8 have?
There are no 'nucleons' in an Oxygen atom. You mean 'neutrons'. As all the mass of an atom is in its nucleus (made up of 'protons' and 'neutrons') and as the Atomic Number is the count of how many 'protons' there are, if you subtract the Atomic Number form the Atomic Mass, you get the number of 'nutrons'. 17-8=9.
