How does zinc behave and react?
Zincis a highly electropositive element and can displace hydrogen acids.It reacts with non metals to form binary compounds like ZnO,ZnS.
Are metalloids metals?
No. They have a superficial resemblance to metals as they look shiny. However in other respects they are quite different . They are brittle rather than ductile; semiconductors rather than good conductors. They do form ionic compounds where they are cations, but generally form covalent compounds. However there are compounds where they form anions when reacted with highly electropositive metals.
For detection of foregin element why is sodium fusion carried out?
oraganic compound are covalent in nature and they do not react with inorganic reagents so that they should be converted into ionic compounds .since sodium is highly reactive and electropositive metal ,it form ionic compound .NA+C+N...................NaCN(SODIUM CYNIDE)2Na+s......................Na2sNa+x.........................Nax
What type of element is rubidium?
Rubidium (Rb) occurs naturally in minerals such as Pollucite, Carnallite and Lepidolite.
What is the physical state for strontium?
Strontium is a soft silver-white or yellowish metallic element that is highly reactive chemically. The metal turns yellow when exposed to air.
What are the properties of lanthanides and actinides?
The lanthanides and actinides are part of the inner transition metals. Actinides are all radioactive, highly electropositive and tarnish readily in air. Lanthanides burn easily in air, have high melting and boiling points and are strong reducing agents.
What explain is negative charge on the oxygen atom within the water molecule?
Oxygen atoms are highly electronegative and pull electrons away from the electropositive hydrogen atom.
Does iron react with tin?
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
Are Lithium chloride held by a covalent bond?
Li is highly electropositive and Cl is highly electronagetive. therefore an ionic bond is formed
Does iron react with tin nitrate?
iron being highly electropositive it does not react with covalent compound formed by two electropositive elements. that is tin nitride.
Is cesium highly metallic?
Yes, metallic and highly reactive to water ('burns' on humid air!) and oxygen
What is the most electropositive element?
Cesium is the most electropositive stable element. Francium is more electropositive (at least in theory) but only about 30 grams exists on the entire planet as it is highly radioactive so no one has been able to check.cesium is most electropositive element in periodic table.Ceasium
Is barium a metallic element highly radioactive and chemically?
No. It is not radioactive.
How copper can be extracted by hydrometallurgy but not zinc?
zinc is more electropositive and therefore is highly reactive metal.hence it can not be easily displaced from its solution of ZnSO4.on the other hand,copper is less electropositive and can be readily displaced from its solution more active metal such as zinc. Zn + Cu2+ ------> Zn2+ + Cu
Is there any ionic bonds between metallic atoms?
Strangely enough yes. There is a class of compounds called Zintl compounds after there discoverer. He reacted highly electropositive alkali metal e.g. sodium with post transition metals (group 13, 14, 15). Na2Tl with a strange Tl48- anion analogous to the P4 molecule. These compounds are diamagnetic and brittle.
What pair of elements are most likely to form an ionic bond?
Highly electronegative and highly electropositive elements, e.g. Fluorine, Clorine, Oxygen, or Nitrogen and Sodium, Potassium, Rubidium, Cesium or Barium.
Does covalent bonding occur between salt like Na Cl?
No, NaCl is an ionic salt. Since, chlorine is highly electronegative and sodium is highly electropositive therefore, the bonding between them takes place by ionic bond.
