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.
What else can I help you with?
What is the subatomic particles on which the atomic number is based?
Number of protons in the nucleus is the atomic number.
The atomic number is the same as the same as the number of these particles what are they?
The atomic number is the number of protons in the nucleus. The protons are positive particles, and so the number of them is matched by the number of electrons orbiting the nucleus. The organisation of the electrons determines how an element behaves when it reacts.
How do protons and neutrons relate to an elements atomic number?
Protons are positively charged particles found in the nucleus of an atom. The number of protons in the nucleus determines the element's atomic number. Neutrons are neutral particles also found in the nucleus, and together with protons, they determine the atomic mass of the element.
The atomic number for an element is the total number of subatomic particles?
False; the atomic number is the total number if protons in the nucleus only.
What is the mass number of copper?
AMU (Atomic Mass Unit) is the SI masses of particles for nucleus.
What can the atomic number and what things can it identify?
The atomic number is the number of protons in the nucleus of an element. It is what determines what kind of an element it is. When you change the number of protons in the nucleus, you change the type of element.
What is ment by atomic number?
Atomic Number is the amount of Protons (positively charged subatomic particles) contained in the nucleus of an atom.
How do atomic numbers relate to the number of particles in an atom's nucleus?
Atomic Number = the Number of Protons in the nucleus, = The number of electrons ( in the neutrally charged atoms). Do NOT Confuse with Atomic Mass , which is the total number of protons AND neutrons in the nucleus.
Protrons are particles that are?
Protons are the positively charged particles that are present in the nucleus of the atom and their number determines the atomic number of the atom.
What is the atomic number of the nucleus?
The atomic number is the number of protons in a nucleus.
What of these subatomic particles are represented by atomic number?
Protons are the subatomic particles represented by the atomic number of an element. The atomic number is equal to the number of protons in the nucleus of an atom, which determines the element's identity on the periodic table.
The atomic number is the same as the number of these two particles?
The "Atomic number" of an element corresponds to the number of only the protons in the nucleus of its atoms. Add to that the number of neutrons that are also in there, and you have the "Atomic weight".
