Why are group 1 and group 7 found as compounds in the periodic table?
they are found as element because in group 1 they react
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
Name three signs of a chemical change that occur as a log burn in a fireplace?
1) heat is evolved 2) it is quite difficult to react 3) new compounds are formed while others react point 3 is the most important as a chemical change is one in which new compounds are formed.
What is produced when group 1 elements react with nonmetal elements?
Usually salts, from the metallic elements in group 1. However, note that hydrogen is also in group 1 and can not form salts, although it forms many other kinds of compounds.
What group will react with alkali metals to form ionic bonds?
halogens (group 17) and oxygen family (group 16)
Why are group 1 and group 7 found as compounds in the periodic table?
they are found as element because in group 1 they react
Why is group 1 metals called alkali metals?
They're metals that form alkaline compounds when they react with water.
Why group 1 and group 2 elements do not occur free in nature?
Group 1 and group 2 elements are reactive metals and react readily with water. They also react readily at high temperatures with oxygen. Over the millenia any free deposits would react to form compounds.
Which group on the Periodic Table of the Elements contains elements that react with oxygen to form compounds with the general formula X2O?
group 1 elements.

Why do elements from group 1 form compounds easily?
The elements in group 1 combine easily with other elements to form compounds because they are trying to get rid of their extra electrons. That is why, for example, potassium will react strongly in water. Hope this helps.
Which group of elements reacts violent with elements in group 1?
Francium would react most violently with hydrochloric acid but all of them would react violently. Cesium and Rubidium would certainly react explosively. Potassium would be very violent and catch fire. Sodium would be quite violent.

Usually salts, from the metallic elements in group 1. However, note that hydrogen is also in group 1 and can not form salts, although it forms many other kinds of compounds.
Which compounds contains an ionic bond?
In general, when an element in group 1 or group 2 combines with elements in group 16 or group 17, ionic bonds are formed between the two elements.
Compounds contains an ionic bond?
In general, when an element in group 1 or group 2 combines with elements in group 16 or group 17, ionic bonds are formed between the two elements.
Why do chemists use compounds instead of group 1 and 7 elements?
It is because the group 1 and 7 elements have a high reactivity. The reactivity is far too high to use on there own because the elements in these groups react with air and/or water.
What transition metals have a valence of 1?
Compounds formed from the last group -so Cu, Ag, Au. Copper and Silver in particular have quite a few compounds with valency 1. AgCl, AgBr, AgI etc. Cu (I) analogues also.
