What else can I help you with?
What is so reactive they are never found in uncombined nature?
Elements that are highly reactive, such as alkali metals (like sodium and potassium) and halogens (like fluorine and chlorine), are never found in uncombined nature. This is because they readily react with other elements to form compounds, seeking stability through chemical bonding. For example, alkali metals react vigorously with water and air, while halogens readily form salts with metals. Their high reactivity means they exist primarily in combined forms, such as salts or minerals.
Are alkali metals found as pure elements in sea water?
Alkali metals exist only as salts.
What charge do alkali metals form when they react with a halogen?
here r the possisble answers: both atoms lose 1 electron a covalent bond forms metal gains an electron and the nonmetal loses an electron metal loses an electron and non metal gains an electron
What group of elements reacts vigorously with water and halogens?
All of the alkali metals, periodic column 1 excluding hydrogen in a wide form periodic table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
Are alkali metals are fairly unreactive?
Alkali metals are actually highly reactive due to their tendency to lose their outermost electron in chemical reactions. They readily react with water, oxygen, and halogens to form various compounds and salts. They are stored under oil or inert gases to protect them from reacting with air or moisture.
Do bases react vigorously with many metals?
No, Acids react with metals to form salts.

Acids and alkali's react together to make salts and what?
Usually they react to form a slat and water.
What groups are the very reactive elements from?
The very reactive elements are typically found in Group 1 (alkali metals) and Group 17 (halogens) of the periodic table. Alkali metals tend to react violently with water, while halogens are known for their high reactivity and tendency to form salts with metals.
Most salts (alkali metals)?
Li, Na, K, NH4
What group of elements reacts vigorously with water and halogens?
All of the alkali metals, periodic column 1 excluding hydrogen in a wide form periodic table, and all but the two lightest alkaline earth elements, periodic table column 2 excluding beryllium and magnesium, have the reactivity specified by the question.
What are the examples of weak salts?
These salts are weak electrolytes: examples are acetates, formates etc. of alkali metals.
What salts are soluble?
Those salts which can dissolve in water.because water is a solvent and salts are solute.
Halogens form what when mixed with alkali metals?
The products of the reactions are ionic salts.
Which group reacts with alkali metals to from salts?
Halogens, such as chlorine, iodine or fluorine.
Does metal react with bases to produce salts?
Yes, metals can react with bases to form salts through a process called neutralization. The metal hydroxide and the base react to form a salt and water. The salt formed will depend on the specific metal and base involved in the reaction.
