Lithium is two of these but at the same time neither. It's an element.
It is best described as an element, a type of atom with unique properties. If the number of neutrons varied, the multiple lithium atoms would be called isotopes. As for neutral vs. ion, if the number of protons is equal to the number of electrons, it is neutral. If it is not, it is an ion, specifically anion (less protons) or cation (more protons). It will always be a neutral atom or ion.
It will always be an isotope, but only called so when in a group of lithium atoms with various numbers of neutrons.
Neither. Tungsten is a transition metal.
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.
1. An atom is neutral because hasn't an electrical charge. 2. An ion has an electrical charge, positive or negative.
The lithium atom lose an electron.
Hydrogen atom is neutral.
The lithium ion is essentially the same as the lithium atom, except it has lost 1 electrons. The number of protons and neutrons remain the same. Thus, the lithium ion, Li+ has 3 neutrons, just like the lithium atom.
It is an isotope of a neutral atom.
An alumimium atom is electrically neutral and it is an isotope of aluminum.
A chromium ion is not neutral. By definition an ion is not neutral. All atoms belong to an isotope, but that has nothing to do with whether the atom is ionized or not.
Neutral atom. An atom of nitrogen will also be an isotope of nitrogen.
Helium is a neutral atom that has several isotopes and can become an ion.
Bromine is a chemical element and has several isotopes.
Lithium loses one electron when fulfilling the octet rule. A neutral atom of lithium will have the same number of electrons as protons, 3. Therefore, a lithium ion will have one less electron, 2.
1. An atom is neutral because hasn't an electrical charge. 2. An ion has an electrical charge, positive or negative.
The lithium atom lose an electron.
A lithium ion has three protons and 2 electrons - Li+. A neutral lithium atom has 3 electrons, but loses one to form an ionic bond with a non-metal.
A lithium ion has a positive overall charge.
Hydrogen atom is neutral.
