WebWastewater . If selenium is oxidized, it is present as the anion selenate (SeO 4 2-) that can be removed from solution with an anion exchange resin.. AmberLyst™ A21 Weak Base Anion Resin will remove weak acids, like selenate from water.The influent should be weakly acidic, pH of 2-5. This weak base anion resin will also remove other weak acids like … WebA cation and an anion slowly move towards each other. What happens to the strength of the electrostatic force between them?

Beryllium - Wikipedia
WebWhen an atom of calcium Ca forms an ion by losing two electrons What is the ion’s type and charge? A stable calcium atom contains 20 protons and 20 electrons. If 2 electrons are lost, then there are more protons than the electrons. Therefore, a calcium ion with a net positive charge is formed. This type of ion is called a cation. WebNaively, you might postulate that beryllium and chlorine would form the ionic compound BeCl2. Usually, chlorine (a very electronegative element) would pull the valence electrons of a metal so strongly toward it that the electrons would effectively transfer from the metal to chlorine; the resulting cation and anion would form an ionic compound. WebIons are identified by a superscript that shows the sign and size of the electric charge – for example Ca +2. There are two types of ions: cations and anions. A cation has a net positive electrical charge, which means it has more protons than electrons. An anion has a net negative electrical charge, which means it has more electrons than protons. sets de dl mu online
