Which group do alkali metals bond with?
Alkali metals are electropositive so they want to react with halogens which are more electronegative.
How would you identify metals in the periodic table?
On some periodic tables metals have a different color.
Acids combine with active metals to give off H2?
SINCE active metals are more electropositive than of hydrogen it undergoes an displacement reaction. 2Na+2HCl = 2NaCl + H2
What are the features of metals and non-metals?
AnswerFeatures of Metals: Metals are characterized by the lustrous shine they provide. They also conduct electricity, are electropositive in nature and react with mineral acids to liberate hydrogen. They are usually solid at 20 degrees celcius. They are usually brittle and hard, but those like sodium are waxy and can be cut with the help of a knife. Features of non-metals: Non-metals may be solids, liquids or gases. They do not conduct electricity under normal conditions. They may be electropositive or electronegative in nature. If solids, they are usually powdery or lumps without luster.
Why alkali metals form ionic hydrides?
SHORT ANSWER: the difference in electronegativities between H and Alkali metals is high, so the bonds are more ionic.
Why are Metals are often referred to as electropositive?
Why metals are electron positive in nature?Because by having an octet as their outer electron shell they will become more stable. For metals it's easier to shed electrons to achieve an octet than it is to achieve it by gaining them.

What are the deferances between metals and mirerals?
The differences between metals and minerals include the fact that metals are atoms that are electropositive. Metals are also harder and stronger than most minerals.
Would copper and calcium react when put together?
No, they will not react when put together. This is because both calcium and copper are electropositive metals. No two electropositive elements or electronegative elements react under normal conditions.

Why Magnesium React with Hydrochloric Acid violently?
In general, acids react with metals in a replacement reaction, since metals can replace the hydrogen component of the acid. The more electropositive the metal is, and the stronger the acid it, the more energetic the reaction will be, and in the case of magnesium reacting with hydrochloric acid, we have a highly electropositive metal reacting with a very strong acid.

What are electropositive elements?
An electropositive element is one with very low electronegativity. These are typically the metals (alkali metals, alkaline earths, etc.). In order to form a stable valence shell configuration, they most easily lose electrons.
Why does the oxidation number of all metals on the periodic table have a positive charge?
Metals are electropositive elements and have low ionnisation enthaply, so there tendency to lose an electron is very high, so they show only positive oxidation states.
Why alkali metals form ionic hydrides?
SHORT ANSWER: the difference in electronegativities between H and Alkali metals is high, so the bonds are more ionic.
What is the oxidation number of hydrogeon when it is combined with a metal?
Hydrogen is a non metal. Metals are electropositive than hydrogen. Therefore, hydrogen atoms in metal hydrides have oxidation number -1.
