calcium salts are burning with brick red color
Name the element that has 2 valence electrons is an alkaline metal and found in bones?
The answer your teacher is expecting is "calcium", though your teacher should have worded the question better; there are no alkali metals with 2 valence electrons. Calcium is an alkaline earth.
What are alkaline earth metals?
They are a series of elements, or metals, on the Periodic Table of Elements. The alkaline earth metals are: beryllium, magnesium, calcium, strontium, barium, and radium (i.e, the ones with two electrons in their outer shell and common oxidation state +2, right next to the alkali metals with common oxidation state +1). They're all silvery-colored and soft, and they combine with water to form alkaline hydroxides, but not as readily as the alkali metals do.
Examples of alkaline earth metals?
The alkaline earth metals are Group IIA of the periodic table. Alkaline earth metals are metals with a valency of '+2'. They are:Beryllium (Be)Magnesium (Mg)Calcium (Ca)Strontium (Sr)Barium (Ba)Radium (Ra)
Are sodium calcium and chromium metals nonmetals or metalloids?
Sodium and calcium are metals, while chromium is a metal.
Is Calcium iodide a metal?
No compounds are metals. All metals are elements, although some metals (e.g. brass) are mixtures of metals.
Is calcium a metal or non metal?
Yes - calcium is a metal. Calcium is classified as an "alkaline earth metal" in the periodic table. The alkaline earth metals are also known as "group 2 elements." The periodic table divides the metals into 5 groups: alkali metals, alkaline earth metals, inner transition metals, transition metals, and post-transition metals. Besides these metals, the periodic table also includes the metaliods, and non-metals. The nonmetals include all the noble gases, all the halogens, and the elements Carbon, Nitrogen, Oxygen, Phosporous, Sulfur, and Selenium. Hydrogen is also normally considered a non-metal although it is theorized that at very high pressures (greater than ~100-500 GPa) hydrogen would become metallic.
Is calcium or potassium an hallogen?
Calcium or Potassium are not halogens but metals.
What metals would calcium nitrate react with?
Calcium nitrate can react with metals like magnesium and aluminum to form their respective nitrates. It is not typically reactive with most other metals since calcium tends to be more stable in its compounds.
Name two elements that are alkaline earth metals?
Two elements that are alkaline earth metals are calcium and magnesium.
Are metals Na Ca Al As Cl?
Metals are sodium, calcium and aluminium.
What family of metals do sodium and calcium?
nothing
What do calcium and iron do?
Both iron and calcium are metals. Iron is a transition metal, calcium is an alkaline earth metal.
What element does the element calcium belong to?

Which is a hallogen poatssium or calcium?
Neither Potassium nor Calcium is a halogen since both are metals.
