Strontium

The strontium ion is Sr2+ with the same electron configuration as Kr. Sr element has an atomic number of 38- the neutrl Sr tom has 38 protons in its nucleus and 38 electrons - therefore the ion Sr2+ has 2 less - 36.

Strontium (Sr)

Melting points: 1050 K, 777 °C, 1431 °F

Boiling points: 1655 K, 1382 °C, 2520 °F

A mineral found near Strontian in Scotland was found to contain a new element in 1790 by A crawford.

Strontium is classified as an alkaline earth metal. It belongs to group 2 on the periodic table and shares characteristics with other elements in this group, such as calcium and magnesium. It is a soft, silver-white metal that is highly reactive with water and air.

The formula for strontium iodide is SrI2. It is formed by the combination of strontium cations (Sr^2+) and iodide anions (I^-).

Alkaline earth metals

Strontium is a mixture of 4 stable isotopes: 84, 86, 87, and 88. Since strontium has 38 protons these isotopes have 46, 48, 49, and 50 neutrons respectively.

These elements are grouped together because they all have two valence electrons in their outermost shell, which gives them similar chemical properties. This group is known as Group 2A, also called the alkaline earth metals, and they are known for being reactive and forming ionic compounds readily.

The formula of strontium carbide is Sr2C2. It consists of strontium (Sr) cations with a 2+ charge and carbide (C) anions with a 2- charge.

The correct formula for strontium sulfide is SrS. It consists of one strontium (Sr) ion and one sulfide (S) ion, which allows them to combine in a 1:1 ratio to form the compound.

Strontium is a metal, Sr is the periodic symbol.

The electron configuration of strontium is 1s22s22p63s23p63d104s24p65s2.

The formula for strontium acetate is Sr(C2H3O2)2. It consists of one strontium ion (Sr2+) and two acetate ions (C2H3O2-).

You can tell how many protons an element has from its atomic number. So the atomic number of Strontium is 38..so it has 38 protons.

Long-hand version: 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 Short-hand version: [Kr] 5s2

36 electrons are there in Sr2+ ion

Strontium chloride is an ionic compound. Strontium, being a metal, donates its electrons to chlorine, a nonmetal, resulting in the formation of ionic bonds between the two elements.

Strontium chloride has ionic bonds. In this compound, strontium donates an electron to chlorine, forming positively charged strontium ions and negatively charged chloride ions that are held together by electrostatic attraction.

Strontium is commonly purified through a process called fractional crystallization. This process involves dissolving strontium compounds in a solvent and then allowing crystals to form as the solution cools. The pure strontium crystals can then be separated from the impurities.

NO!!!!

Each element has it own ground state electron configuration.

Rubidium is [Kr] 5s1

Strontium is [Kr] 5s2.

Notice that strontium has one MORE electron than Rubidium.

The symbol [Kr] is shorthand for the full electron configuration of krypton.

The formula unit for the ionic compound made of strontium and sulfur is SrS, called strontium sulfide.

The bipositive ion of strontium takes the electron configuration of xenon.

You wouldn't expect strontium to gain electrons in a chemical change.

in my high chemical equipment, in my science lab i have found the correct answer and the highly best answer is gas!

this stupid web site doesnt know the answer sorry :(
