The atomic number of an element is FIXED it can not normally be changed.
However, if the element's atom is struck by an atomic particle or the element is radioactive then the composition of the atoms nucleus can be altered. Changes to the composition of the nucleus can cause a NEW element to be formed or indeed split the atom into two NEW smaller/lighter atoms.
What else can I help you with?
Does the atomic number changes when an ion is formed?
No, the atomic number remains the same when an ion is formed. The atomic number is determined by the number of protons in an atom, which does not change when an atom becomes an ion by gaining or losing electrons.
What is the change in the atomic number when an atom emits gamma radiation?
The atomic number does not change when gamma radiation is emitted.
How does the change in the carbon's number of neutron affect the atomic number?
The number of neutrons has no influence on the number of the atomic number. Only protons do, and they only change in nuclear chemistry.
How are the atomic number and mass number of a nuclide affected by the emisson of gramma radiation?
Any change of the atomic number.
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.
How does a neutral atom change when its number of protons electrons or nuetrons change?
The element becomes a new element becuase the atomic number would change. For example if you added a proton to Hydrogen-atomic number 1, it would become helium-atomic number 2
What is the change in atomic number after an alpha decay event occurs?
The change in atomic number after an alpha decay event occurs is a decrease of 2.
Why atomic number not change during a chemical reaction?
chemical reactions are involved by the participation of electrons only.During chemical reaction number of protans remains as it is. No change in number of protans.Number of protans is also called atomic number.So no change in number of protans means no change in atomic number. That's why atomic number is not change during a chemical reaction.
What information in the periodic table indicats the number of protons in a atom?
The atomic number represents the number of protons in the element. This number is unique to that element, if you change the atomic number (number of protons) then you change the element.
Why would an elements atomic number change after transmutation?
Transmutation by definition means the conversion of one element into another, and so it follows that its atomic number must also change. Every element has a unique atomic number.
How does the atomic number change in a period?
When going left to right across a period, the atomic number of element increases.
What number on the periodic table defines the element and does not change?
Atomic number
