Alkaline Earths

The chemical formula of beryllium chloride is BeCl2.

Alkaline earth metals have 2 electrons in their outer shell.

Alkaline-earth metals do react with oxygen, forming oxides. The reaction tends to be less vigorous compared to alkali metals, as alkaline-earth metals have a higher ionization energy. Examples of alkaline-earth metal oxides include magnesium oxide (MgO) and calcium oxide (CaO).

The lightest alkaline earth metal is Beryllium(Be) having atomic mass 9.012 dalton. The heaviest element in this family is radium.

Alkaline-earth metal ions typically have a charge of +2. This is because they lose two electrons to achieve a stable electron configuration, resulting in a 2+ charge. Examples of alkaline-earth metals include calcium (Ca2+), magnesium (Mg2+), and barium (Ba2+).

BeN2 is beryllium nitride, a chemical compound made of beryllium and nitrogen atoms. It is a hard, high-melting-point material with potential applications in electronic and optoelectronic devices.

Calcium.

Calcium-40 isotope has 20 protons, 20 electrons and 20 neutrons.

Calcium is the alkaline earth metal extracted by milking machines.

No, group 13 elements, such as boron, aluminum, and gallium, are not alkaline earth metals. Group 13 elements are known as the boron group or triels, and they have different characteristics than alkaline earth metals, which are found in group 2 of the periodic table.

Alkali metals are highly reactive, soft metals that readily lose their outermost electron to form ions with a +1 charge. They are located in Group 1 of the periodic table. Alkaline earth metals are also reactive, but less so than alkali metals, and they lose two electrons to form ions with a +2 charge. They are located in Group 2 of the periodic table.

Chlorine is a Halogen.

Along with the rest of the elements in the group.

Mostly ending with ine.

Bromine and Fluorine for example.

Two elements that are alkaline earth metals are calcium and magnesium.

Beryllium and magnesium have two electrons in their outermost energy level, as do all Group 2 elements.

Compared to what? But it would be less reactive because the s orbital is filled, the electrons are all paired. If you mean "Why is beryllium the least reactive of the Group II alkaline earth metals?", then this is because it has the least electron shielding, having an electron configuration of 2, 2. Beryllium is at the top as the first of the Group II alkaline earth metals, and reactivity increases as you go down Groups I and II.

Beryllium is the most electronegative alkaline earth metal.

Metallic substances which can cause fires are alkali metals such as Sodium or sometimes alkaline earth metals like Magnesium. Water is not to be used under these circumstances because it will combine with the metal and form Hydrogen gas, which is very inflammable. These fires are best extinguished with sand, CO2 or bicarbonate based extinguishers.

Beryllium's chemical symbol is Be.

Barium is the alkaline earth metal known for its use in flares and fireworks due to its vibrant green color when burned. Barium salts, like barium nitrate or barium chloride, are commonly used as colorants in pyrotechnics to produce different hues of light.

Beryllium typically has 4 neutrons in its nucleus, so an isotope with 5 neutrons would have a mass number of 9. Therefore, the atomic mass of beryllium with 5 neutrons would be approximately 9 atomic mass units (amu).

To make a simple atom model of beryllium, you can use two small Styrofoam balls representing protons and two small Styrofoam balls representing neutrons in the nucleus, with two larger Styrofoam balls representing electrons orbiting around the nucleus. You can attach these components together with toothpicks to represent the atomic structure of beryllium.

i dont know either maybe a gas?

i dont know either maybe a gas?

for those who dont know: beryllium is a solid!

Electronic configuration of beryllium: 1s2.2s2.

Beryllium is a solid metal at room temperature.

i don't know but could it be lava? I'm only in year nine so I'm practically guessing and the only hot thing i could now over is lava...

^^ lava is not an element, but my best guess would be Beryllium as it has a boiling point of 2,970 degrees celcius and it is an alkaline earth metal.
