because it becomes more complex and the nuclei has to mange more neutrons

What happens to the number of electrons in an atom when the atomic number increases?
The atomic number is specific to the element itself - not the quantity. It does not change as you add in more of the element.
How does atomic number change as you move from left to right?
I'm guessing you are acking Atomic Radius. The atomic radius decreases and you go left to right because the shielding effect from the lower electrons stays almost constent while the elements gain more protons adding to the effective nuclear charge pulling the electrons closer to the nucleus.
How is the mass number different from the atomic number of an atom?
Atomic number of an element is the number of protons that an atom of an element contains. The atomic weight (the mass of the atom) is measured by not only the mass of the proton(s), but by the mass of the nuetrons and electrons too.
What is the total number of neutrons in the nucleus of a neutral atom that has 19 electrons and da mass number of 39?
The mass number is the total number of protons and neutrons (together known as nucleons) in an atomic nucleus.Thus add the number of neutrons (20) to the atomic number (which is a count of the number of protons) 19 to give a mass number of 39.
What is used to identify an atom?
Atoms are normally identified according to the element of which that atom is an example. And that, in turn, is determined by the number of protons in the atom's nucleus. So, any atom that has just one proton is a hydrogen atom. If it has two protons it is a helium atom. And so forth.
How do the number of protons change as atomic number increases by one?
the number of protons change because of the more protons you add on
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 happens to the number of electrons in an atom when the atomic number increases?
The atomic number is specific to the element itself - not the quantity. It does not change as you add in more of the element.
What atomic particle has a positive change?
Protons
Is neutrons and atomic number the same?
In a periodic table, yes. For example, sodium's atomic number is 11, that means it has 11 protons and electrons because in the periodic table the elements have no charge. However, the sodium ion (Na+) has 1 positive charge, which means that metal lost 1 electron. Therefore, the number of protons never change because otherwise it would be another element, but the number of electrons will decrease by 1.Na = 11 protons and electrons.Na+ = 11 protons and 10 electrons = 1+ chargeI hope that answers your question
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.
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 major change occurs as you move from left to right across periodic table?
the atoms of the element are less reactive and smaller. they are smaller because of the larger amount of valence electrons compacting the atom.What_moves_left_to_right_on_the_periodic_table
Does the atomic number changes when an ion is formed?
No, the atomic number does not change when an ion is formed. The number of protons does not change when an ion is formed, so the atomic mass would not change.
Do all potassium K have the same atomic number?
Yes. The atomic number is the number of protons in an atom. Potassium always has 19 protons, and so its atomic number is 19. As soon as there is a change in the number of protons, then the element is different.
How do you calculate protons and in ions?
The protons are always the same as their matching atomic number. This is also true of ions. Protons never change.
What is proton or atomic number?
A proton is a subatomic particle in the nucleus of an atom. Protons have a positive electric charge. The atomic number of an element is equal to the number of protons in the nucleus of one of its atoms. Therefore, if you change the number of protons in an atom, you change the element.
