What else can I help you with?
Is calcium metallic?
Yes, calcium is a metallic element. It is a soft, silvery-white metal that is highly reactive and essential for various biological functions in the human body.
What is an example of a valuable non metallic mineral?
Diamond is an example of a valuable non-metallic mineral. It is highly valued for its beauty and used in jewelry as well as in industrial applications due to its hardness and unique properties.
Is ytterbium reactive or nonreactive?
Ytterbium is a reactive element, but it is primarily reactive with air and water, rather than being highly reactive in general. It is not as reactive as some other metals like alkali metals such as sodium or potassium.
What type of element is rubidium?
Rubidium (Rb) occurs naturally in minerals such as Pollucite, Carnallite and Lepidolite.
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 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 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 cesium highly metallic?
Yes, metallic and highly reactive to water ('burns' on humid air!) and oxygen
Is barium a metallic element highly radioactive and chemically?
No. It is not radioactive.
Why isn't francium the most electropositive element?
Although francium is very electropositive, cesium is typically considered more electropositive. This is because francium is rare and highly radioactive, making it difficult to study and utilize for practical purposes. Additionally, the large size of the francium atom leads to some electron shielding, decreasing its electropositivity compared to smaller atoms like cesium.
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.
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 is a metallic?
Metallic usually refers to a finish (paint, trim), meaning it looks(shiny/ highly reflective)or contains metal (old metallic paint had metal flake in it to give a glitter effect.)
What is the electronegativity of potassium?
The electronegativity of potassium is 0.82 on the Pauling scale. It is relatively low compared to other elements, indicating that potassium is a highly electropositive metal.
Is gold a non metallic mineral resource?
Gold is classified as a metallic mineral resource, not a non-metallic one. It is a valuable metal that is highly prized for its use in jewelry, electronics, and other applications due to its malleability, conductivity, and resistance to corrosion.
What are some examples of mineral luster?
Luster is categorized as metallic or non-metallic. Metallic luster is highly reflective, like chrome. Non-metallic is further divided by names such as dull, glassy, adamantine, waxy, silky, pearly, and greasy.
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.
