Strontium

Yes, strontium-90 can be detected in blood samples through laboratory testing. Strontium-90 is a radioactive isotope that can accumulate in bone as well as other tissues, including blood, after exposure to radioactive sources. Detection of strontium-90 in blood can indicate recent or ongoing exposure to radioactive contamination.

No, strontium is more reactive than calcium. This is because strontium is located below calcium in the periodic table and thus has a larger atomic size, making it easier for strontium to lose its outermost electron and react with other elements.

In strontium, the electron configuration is [Kr] 5s^2 4d^2. The pairing of electrons in the 5s orbital is due to Hund's rule, which states that electrons fill empty orbitals before pairing up. The 4d orbitals can accommodate up to 10 electrons, with the first 2 occupying separate orbitals before pairing starts.

The unbalanced equation for the reaction of barium oxide (BaO), calcium oxide (CaO), and strontium oxide (SrO) with aluminum (Al) is:

BaO + CaO + SrO + Al -> Ba + Ca + Sr + Al2O3

The chemical formula for the compound Strontium arsenide is SR3AS2.

True. Both the strontium ion (Sr2+) and xenon (Xe) have the same number of electrons when considering the ionization states: 54 electrons. This means they are isoelectronic.

In reactions, strontium tends to lose electrons because it is a metal. It is in Group 2 of the periodic table, which means it has 2 valence electrons and readily gives them up to achieve a stable configuration.

Strontium hydroxide is a base, not a salt. It is a chemical compound composed of strontium, hydrogen, and oxygen, and it dissociates in water to release hydroxide ions, making it a strong base.

The flame of strontium chloride is a bright red color.

Strontium chloride has a high melting point because of the strong attraction between the strontium cations and chloride anions in its crystal lattice. These ionic bonds require significant energy to break, leading to a high melting point.

Phosphorus will form the P3- ion, strontium will form the Sr2+ ion, oxygen will form the O2- ion, gallium will form the Ga3+ ion, and lithium will form the Li+ ion.

The wavelength of strontium nitrate is not a defined property of the compound itself. The wavelength of a substance can vary depending on the conditions under which it is being studied, such as in a spectroscopic experiment.

When strontium is burned, it produces a bright red flame due to the presence of strontium ions. This red color is commonly used in fireworks to create red hues in displays. It is also used in road flares and signal lights for its distinctive red emission.

Strontium bromide has no apparent trade name; most likely its name and chemical formula is simple enough that it would not need one.

Yes, strontium hydroxide is considered a strong base. It is a group 2 metal hydroxide that dissociates almost completely in water to produce hydroxide ions, making it a strong alkali and a good conductor of electricity.

A strontium atom differs from a strontium ion in that the atom has a greater number of electrons compared to the ion. This means the atom retains its neutral charge due to an equal number of protons and electrons, while the ion has lost some electrons and carries a positive charge.

Strontium iodide can be made by reacting strontium carbonate with hydroiodic acid. The balanced chemical equation for this reaction is SrCO3 + 2HI -> SrI2 + CO2 + H2O. This reaction forms strontium iodide, carbon dioxide, and water as products.

Calcium,barium and radium are mostly similar to strontium by properties, because these elements have the same structure of external electron orbits ( outer-shell orbitals 2s).Because of the similarity of the outer shell orbitals these elements are placed in the same group.

Magnesium and beryllium have also the same structure of outer shell orbitals like strontium(2s)but they are more similar to zinc or aluminium than to strontium.

Yes, strontium typically exhibits a shiny metallic luster.

The atomic mass of strontium is not a whole number because it is an average value that takes into account the abundance of different isotopes of strontium in nature. These isotopes have different masses and occur in different proportions, resulting in a weighted average atomic mass that is not a whole number.

The formula for strontium combined with dihydrogen phosphate is Sr(H2PO4)2. In this compound, strontium has a 2+ charge, and the dihydrogen phosphate ion, H2PO4-, also carries a 1- charge, so two dihydrogen phosphate ions are needed to balance the charges.

Strontium shares more properties with barium, as they are both members of Group 2 (alkaline earth metals) in the periodic table. These elements have similar chemical properties due to their position in the same group. Yttrium, on the other hand, belongs to a different group (Group 3) and therefore has different properties compared to strontium.

Yes, strontium chloride is an ionic compound and can conduct electricity when dissolved in water or when molten. In its solid state, strontium chloride does not conduct electricity as the ions are not free to move.

there are no co efficents infront of any of the reactants or products

Strontium can be a neutral atom or a cation.
