If the number of charged and uncharged particles in the center of an atom are 7 and 8 respectively.What is the mass number of the atom?
The charged particles would be protons (+) and would have a mass of 7 ( which would also tell you its atomic number, making this element Nitrogen). If the uncharged particles are eight in number and like protons have a value of one, 7 + 8 = 15 for atomic mass. Since the actual atomic mass of N is 14.007, the difference in mass tells us that we are talking about an isotope of N.
What number of neutral particles in the previous answer 42 is my atomic number?
The atomic number of an element is defined by the number of protons in its nucleus. In a neutral atom, the number of electrons equals the number of protons, meaning the number of neutral particles (neutrons) can vary. If 42 is your atomic number, you have 42 protons, and the number of neutrons would depend on the specific isotope of the element. For example, if considering molybdenum (atomic number 42), it typically has about 54 neutrons in its most stable isotope.
When you subtract the atomic number from the atomic mass of any element you get what?
Atomic mass= Atomic no. + no. of neutrons So when the atomic no. is subtracted from the atomic mass, the result would be equal to the number of neutrons present in the nucleus of the atom of the element.
Nitrogen has an atomic mass of 14 and an atomic number of 7 so the number of neutrons must be?
The atomic mass of an atom is the total mass of its particles. The atomic number is the number of protons in the atom's nucleus. To find the number of neutrons in an atom, we take its atomic mass (the total mass of its particles) and subtract its atomic number (the number of protons and electrons in the atom). A: Lithium has an atomic mass of 7 and an atomic number of 3 so the number of neutrons is equal to 4. (7 - 3 = 4)
Do alpha prarticle share the same atomic number?
An alpha particle is, essentially, a helium nucleus.This means that is has the same atomic number (no. of protons) as Helium does - it just doesn't have the electrons as well.So the atomic number of an alpha particle would be 2.It's also not neutral, and would have a 2+ charge.The mass number of an alpha particle would be 4 as it has 2 neutrons and 2 protons.All alpha particles are helium nuclei, so they all share the same properties.
What happend to the atomic number of an element which emits alpha particle and two beta particle?
THe atomic number would decrease by 2 as alpha particle comes out. But for two beta particles the atomic number would increase by 2. So the atomic number remains unchanged due to emission of one alpha followed by 2 beta particles.

What change in atomic number occurs when a nucleus emits an alpha particles?
An alpha particle has 2 protons and 2 neutrons. This would make the atomic number decrease by 2 and the Atomic Mass will decrease by 4.

Is raduim decays to bismuth how many alpha beta particles are emitted?
Atomic number of radium is 88 and that of bismuth is 83. So atomic number is to be reduced by 5. But as alpha is emitted atomic number reduces by 2. So a beta decay is needed which would increase the atomic number by 1. So 3 alpha decay and one beta decay would make radium into bismuth
Is 40.08 the atomic number?
No. Atomic number is always a whole number. This would be the atomic mass.
To find the number of neutrons in an atom you would subtract what?
You would subtract the atomic number from the mass number.
Which type of particle has an atomic number of -1 and a mass number 0?
This question probably refers to a positron, although I am not sure that the description of it as having a negative atomic number is widely recognized.
What is the atomic number of 30Ar?
The atomic number of Argon is 18. So 30 of them the Atomic Number would be 540.
