What is the atomic number and atomic mass number of the element that is formed in the following nuclear reaction that takes place in the sun?
The atomic number is 2, and the atomic mass is 4 (helium)
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.
Which cation may have atomic number 20 and a charge of 2?
The element is calcium and the cation is Ca2+ ion
What is the formula for the cation formed when aluminum metal is oxidized?
4Al(s) + 3O2(g) --> 2Al2O3(s) where Al has an oxidation number of 3+
Is the Atomic weight for an element the same when it is in an anion or cation?
The weights of atoms are based primarily on the number of protons and neutrons in an atom. This is because protons and neutrons are many times the weight of electrons. Since electrons contribute a minuscule amount, even on the atomic level, to the mass of the atom, the mass of the atom is taken to be the same whether it is a anion of a cation. Remember, it is the number of electrons in an atom that determines whether it is an anion, cation, or a neutral atom. If there is a different number of neutrons it is called an isotope, and will have a different mass. If it has a different number of protons, it is a different atom and will have a different mass.
What is the atomic number of the cation formed in the reaction illustrated in Figure 2.3?
11. The atomic number refers to the number of protons in an atom, including a cation. In this case, the Sodium cation has 11 protons like the Sodium atom.
Atomic no. of the cation?
The atomic number of the cation is the same as the atomic number of the neutral atom.

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 element has 10 electrons when it form a cation with a 1 plus charge?
The element with 10 electrons when it forms a cation with a 1 plus charge is Neon (Ne). Neon has an atomic number of 10, which means it has 10 protons and 10 electrons. The cation is formed when an electron is removed from Neon, leaving it with 9 protons and 1 electron, giving it a 1+ charge. Neon's atomic number: 10 Neon's electrons when forming a cation: 10 Neon's protons when forming a cation: 9 Neon's charge when forming a cation: 1+
What happens to atomic radius size of a cation and why?
When an atom loses an electron to become a cation, the number of electrons decreases while the number of protons remains the same, leading to a stronger electrostatic pull on the remaining electrons. This causes the electron cloud to be pulled closer to the nucleus, resulting in a smaller atomic radius for the cation compared to the neutral atom.
Does the atomic number of the electron when the atom get converted into catayon and anayon?
The atomic number of an atom does not change if the atom is converted into an anion or cation. The atomic number is the number of protons in the nucleus of an atom, and this is not affected by the transfer of electrons that produces ionization of an atom.
What is the formula for the cation formed when aluminum metal is oxidized?
4Al(s) + 3O2(g) --> 2Al2O3(s) where Al has an oxidation number of 3+
What molecule would be formed from atom of sulfur with atomic number 16 and atom formed from hydrogen with atomic number 1?
A molecule formed from a sulfur atom (S) with atomic number 16 and a hydrogen atom (H) with atomic number 1 would result in hydrogen sulfide (H2S). In this molecule, two hydrogen atoms bond with a sulfur atom to form a covalent bond.
What is the ion formed when a metal loses 1 or more electrons?
An ion with missing electrons, and thus a positive charge, is a cation.
