Beryllium is it!
They are:Hydrogen (H) is a gasHelium (He) is a noble gasLithium (Li) is a metalBeryllium (Be) is a metalBoron (B) is a metaloidCarbon (C) is a non-metalNitrogen (N)Oxygen (O)Fluorine (F) is a halogenNeon (Ne) is a noble gas
Any element can have 4 neutrons but most of them aren't metallic. Anyway's on the periodic table it would be Be and that stands for Beryllium
Lithium, Beryllium, Boron, Carbon, Nitrogen, Oxygen, Fluorine, Neon.
no beryllium aluminium silicate is not an element. It is one of the beryllium compounds.

When hydrogen, lithium, and beryllium atoms combine, they form a molecule with the chemical formula LiHBe. This molecule would have a unique set of properties based on the different characteristics of each element.
hydrogen, helium, lithium, beryllium, BORON!
lithium
Lithium is more reactive.
Our sun mostly transforms hydrogen nuclei into helium by fusion, but it also fuses helium with helium, lithium with hydrogen, and beryllium with hydrogen, to make elements as heavy as boron.

Could be lithium (ends with 2s1) or beryllium (2s2)

If "element 5" in this question means the element with atomic number 5, then all of the elements with atomic numbers 1 through 4 have smaller atomic masses. These elements are hydrogen, helium, lithium, and beryllium.
No, normally the only metal considered a light element is Lithium (some lists include Beryllium).
-Hydrogen is a naturally occurring gas the lightest gas. chemical symbol H and atomic number 1. -Helium is a chemical element (part of a group of chemical elements called noble gases) with the symbol He and is gas, the second most common element in the Universe (after hydrogen). -Lithium is a chemical element (symbol Li and atomic number 3) belonging to the alkali metal -Beryllium (Element Symbol is Be) is found in nature in various mineral compounds, not in the elemental form as they are so reactive. Atomic Number of Beryllum is 4. classified as an Alkaline Earth Metals.
