Does the atomic number of the element change when its atom forms ion?

No. Atomic Number is defined as the number of positive protons, and when a ion is formed(irrespective of cation or anion) only negative electrons will be lost or added hence the proton number is constant.

What are the atomic numbers and mass numbers of the stable and radioactive forms?
1. The atomic number is equivalent to the number of protons in the atomic nucleus of a chemical element. The number of protons is identical for all the isotopes of an element. 2. The mass number is the sum of protons and neutrons in the atomic nucleus of an isotope.
What do you call the several different forms of an element having different atomic mass and number of neutrons?
We call these different "flavors" of an element the isotopes of that element.
Which best describe isotopes?
any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number.
Is calcium a noble gas?
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
How are isotopes the same but different?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
Is it true that the element's mass number determines how the compound will form?
No. The element's atomic number determines how it forms compounds.

Where is the particle proton found?
All atomic nuclei contain protons (hydrogen has only one). The number of protons in the nucleus determines which element it forms, this is called the atomic number
Where is obsidian on the periodic table and which number element is it?
Obsidian is not an element, therefore it does not have an atomic number or a place on the periodic table. Obsidian is a volcanic glass which forms when lava cools rapidly.
What element helps calcium to maintain bone strength and atomic number fifteen?
The element with the atomic number 15 is phosphorus. Together with calcium, hydrogen, and oxygen it forms the hydroxyapatite, Ca5(PO4)3OH, which is found in both bones and tooth enamel.
What is phosphorus an element or compound?
Phosphorous is an element with chemical symbol P. It has atomic number 15 and is a non-metallic element. There are two major forms, one is white and one in red.
Which best describe isotopes?
any of two or more forms of a chemical element, having the same number of protons in the nucleus, or the same atomic number.
What is something and atom and isotope have in common?
Isotopes are different forms of the same element which have different numbers of neutrons in their atomic nuclei. A given element is identified by the number of protons in its nucleus; that's its atomic number. Two different isotopes of the same element have the same number of protons, but each has a different number of neutrons in its nucleus. Different isotopes of the same element are chemically the same.
Isotopes are forms of the same element that differ in what?
Yes, isotopes of an element are the same element but with different numbers of neutrons in the nucleus and thus different atomic masses.
Is calcium a noble gas?
Argon (atomic number 18) is the noble gas that is nearest to calcium (atomic number 20)
