Beryllium - Wikipedia
Beryllium is a chemical element; it has symbol Be and atomic number 4. It is a steel-gray, hard, strong, lightweight and brittle alkaline earth metal. It is a divalent element that occurs naturally only in combination with other elements to form minerals. Gemstones high in beryllium include beryl (aquamarine, emerald, red beryl) and chrysoberyl.
Beryllium | Properties, Uses, & Facts | Britannica
beryllium (Be), chemical element, the lightest member of the alkaline-earth metals of Group 2 (IIa) of the periodic table, used in metallurgy as a hardening agent and in many outer space and nuclear applications.
Beryllium - Element information, properties and uses | Periodic Table
Beryllium is a silvery-white metal. It is relatively soft and has a low density. Beryllium is used in alloys with copper or nickel to make gyroscopes, springs, electrical contacts, spot-welding electrodes and non-sparking tools. Mixing beryllium with these metals increases their electrical and thermal conductivity.

Beryllium Facts, Symbol, Discovery, Properties, Common Uses
Beryllium (pronunciation beh-RIL-ee-em [2]), represented by the chemical symbol or formula Be [1], is a light-weight, high-strength element belonging to the family of alkali earth metals [3, 15, 41]. Naturally occurring Be has a single stable isotope with mass number 9 [1].
How Many Protons, Neutrons and Electrons Does Beryllium Have?
2024年8月22日 · Beryllium is a classified brittle alkaline earth metal and its symbol is ‘Be’. Beryllium is the 4th element of the periodic table so its atomic number is 4. The atomic number of an element is equal to the number of protons and electrons in that element. Therefore, a beryllium atom has four protons and four electrons.
Beryllium (Be) - Periodic Table

Isotopes of beryllium - Wikipedia
[12] 10 Be is a significant isotope used as a proxy data measure for cosmogenic nuclides to characterize solar and extra-solar attributes of the past from terrestrial samples. [13] Most isotopes of beryllium within the proton/neutron drip lines decay via beta decay and/or a combination of beta decay and alpha decay or neutron emission. However, 7.
Beryllium – Protons – Neutrons – Electrons – Electron Configuration
Beryllium is a chemical element with atomic number 4 which means there are 4 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.
