An ion is an atom with electrical charge, a cation or an anion.
Isotopes are atoms of the same element but having different number of neutrons.
A hydrogen atom refers to a single neutral hydrogen particle consisting of one proton and one electron. Atomic hydrogen, on the other hand, typically refers to a collection of hydrogen atoms in a gaseous state, where the atoms are not bonded to each other.
From the given elements, Mg has the largest atomic radius, hence the size.
Atomic mass is defined for atoms. Molecular mass is defined for molecules or compounds. Atoms bond with each other to form compounds.
For neutral atoms the atomic number is equal to the number of electrons.
Different atomic numbers represent different elements.
atomic number = number of protons = number of electrons (in a neutral atom)
The neutral sub-atomic particles in an atom are neutrons and they are found inside the nucleus.
Neutral atoms of neon have the same number of electrons as atoms of fluorine, magnesium, and sodium, excluding helium atoms.
The atomic number is equal to the number of protons and neutrons in a neutral atom.
From the given elements, potassium has the largest atomic radius.
NO. The number of electrons in any neutral atom must be the same as the number of protons. The number of protons is the atomic number, if the atomic number is the same then the atoms are of the same element, not different ones.
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
