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.
Two or more forms of the same chemical element that differ in atomic mass?
Isotopes are two or more forms of the same chemical element that differ in atomic mass due to having a different number of neutrons in their nuclei. These isotopes of an element have the same number of protons and electrons but vary in their overall mass.
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.
The atomic number of a compound indicates the?
The atomic number refers to the number of proton in a particular atom. As a matter of fact, number of proton = number of electrons in an atom. The number of electron changes as the atom forms ion.
Is it true that the element's mass number determines how the compound will form?
No, the mass number of an element does not determine how a compound will form. The properties of compounds are determined by how the atoms of different elements are bonded together, which involves their electron configurations and interactions. The mass number only reflects the total number of protons and neutrons in the nucleus of an atom.

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.
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.
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.
Two or more forms of the same chemical element that differ in atomic mass?
Isotopes are two or more forms of the same chemical element that differ in atomic mass due to having a different number of neutrons in their nuclei. These isotopes of an element have the same number of protons and electrons but vary in their overall mass.
Which best describe isotopes?
Isotopes are atoms of the same element that have the same number of protons but different numbers of neutrons. This results in different atomic masses for isotopes of the same element. Isotopes have similar chemical properties but may have different physical properties due to their varying atomic masses.
What is meant by the statement -this element has 3 isotopes?
The statement means that the element in question has three different forms (isotopes) with varying numbers of neutrons in their atomic nuclei. These isotopes of the element share the same number of protons and electrons but have different atomic masses due to the differing number of neutrons.
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.
Is a plutonium is a mixture or compound or elements?
Plutonium is an element with the chemical symbol Pu and atomic number 94. It is a radioactive metallic element that occurs in varying isotopic forms.
