No sense; atomic number zero and atomic weight zero doesn't exist !
Edit:
!Answer = 0
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
If you mean looking at the next element on the table then the mass would increase. However, the atomic number is only the number of protons in an atom and is not a true indicator of atomic weight. Variations in Neutron count can cause differences in atomic weights.
The ionic charge of an atom or ion can not be determined from the mass number and atomic number alone, because the ionic charge if any depends on the surplus or deficiency of electrons compared to protons in the atom or ion. Ordinarily, the symbol C-12, with no further modification, indicates a neutral atom, which would have zero ionic charge.
The rest mass of a lithium atom can be calculated by adding up the masses of its protons and neutrons. Lithium has 3 protons and 4 neutrons, so the calculated mass would be (31.00727252 + 41.008665 = 7.01600472 u). The rest mass of a lithium atom is approximately 7.016 u, so the difference between the calculated and rest mass is essentially zero.
Zero. There are NO boron atoms with a mass of 10.81 amu. The value of 10.81 is an average of the masses of the isotopes of boron.There are two stable isotopes of boron: boron-10 and boron-11, with masses of 10.012 amu and 11.009 amu. B-10 has a relative abundance of 19.9% and B-11 has a relative abundance of 80.1%.Do the math:10.012 x 0.199 + 11.009 x 0.801 = 10.81 amu
In terms of atomic mass, the atom with a zero value is the neutron, as it has a mass close to zero. However, in terms of atomic charge, an atom with a zero value is a neutral atom, meaning it has an equal number of protons and electrons canceling out their charges.
Mass number is the total number of protons and neutrons in an atom's nucleus. Non-examples of mass number would include atomic number (number of protons in an atom), electron configuration (arrangement of electrons in an atom), and atomic mass (average mass of an atom, taking into account all isotopes).
The number of neutrons in an atom can be calculated by subtracting the atomic number (number of protons) from the mass number. For hydrogen, the atomic number is 1 and the mass number is also 1. Therefore, the number of neutrons in hydrogen is 1 (mass number - atomic number = 1 - 1 = 0 neutrons).
Anywhere between zero, and over a hundred - it depends on the atom (on the element, and the isotope).
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.
The mass number is the total amount of protons and neutrons in an atom (the number of protons is the same as the number of electrons) The atomic number is the number of protons (or electrons) in an atom. To find out the number of neutrons in an atom, you need to take the atomic number from the mass number An atom is normally written like this: Mass number Ca Atomic number The Mass number can be written as (A) and the atomic number can be writtens as (Z)
You can calculate the atomic mass by adding the number of protons and neutrons together, since electrons have a negligible mass compared to protons and neutrons. The sum of protons and neutrons will give you the atomic mass of the atom.
By the sum of protons and neutrons we obtain the mass number of the atom which is written at the top of the atom periodic number. We can also obtain the mass number by adding the atomic number and the number of neutrons because the atomic number and the number of protons are same. You know that scientists have discovered some particles which are smaller than protons and neutrons and these are known as quartz.
The atomic number always corresponds with the number of protons in the atom, therefore, since the atomic number is six, there are six protons in the atom.Because the atom has no specified charge, you can assume that the charge is zero and that there are the same number of electrons as protons, also six.The mass of an atom is the number of protons plus the number of neutrons because electrons are tiny. So, you know there is a mass of 14, subtract six from the protons and you get the neutrons (14-6protons=8neutrons)Hope this helped!!
The atomic number of ammonia (NH3) is zero, as it is a compound made up of nitrogen and hydrogen atoms. Each individual nitrogen atom has an atomic number of 7, and each hydrogen atom has an atomic number of 1.
If the charge on the atom is zero, then the number of electrons is equal to the atomic number. e.g. 126C : atomic number = 6. This means there are 6 protons in the nucleus of the atom. There is no charge on the atom, so number of electrons must equal number of protons to cancel charge (6 electrons).
When you write out the symbol for an isotope, it has two numbers before the chemical symbol....the bottom one is the atomic number (#protons) and the top one is the atomic mass (#protons + # neutrons). Since the letter abbreviation is given, the bottom number is kind of redundant. So, sometimes people will write the abbreviation as the letter abbreviation followed by the mass number. So, Rb-82 would have 37 protons and 82-37 neutrons (45). Beta particles would be written as a beta with the top number being zero (negligible mass for this purpose) and the bottom number being -1. So, if you lose a zero from the atomic mass, there is no change. If you lose a negative one from the atomic number, the atomic number increases by 1. So, for example, Th-234 has an atomic number of 90. Loss of a beta doesn't change its mass (still 234), but changes its identity to 91, which is the element Protocinium (Pa-234).
