A alkali metals
Explanation:
The family of alkali metals have a valency of 1 i.e they have one electron their outermost shell. They are groups of metals that reacts with water and can conduct electricity. The lose their valence electron and they have a net charge of +1 on them.
- Since they are metals, they readily conduct electricity.
- They are called alkali metals because their hydroxides are soluble in water
- They are very reactive metals and not usually found free in nature.
Their valence shells have an electronic configuration of ns¹
Examples are lithium, sodium, potassium, rubidium, caesium and francium.

What is moles of compound?</h3>
Avogadro's number (6.022 x 1023) of molecules (or formula units) make up one mole of a substance (ionic compound). The mass of 1 mole of a chemical is indicated by its molar mass. It provides you with the amount of grams per mole of a substance, to put it another way.
In essence, bond angles indicate that electrons dislike being close to one another. Negative ions are electrons. Negatives don't attract each other. Make a comparison now. A negative person is typically viewed as unpleasant or mean, and you don't want to interact with them.
The configuration or quantity of atoms are not mentioned in an empirical formula. It is typical for many macromolecules, such as silicon dioxide (SiO2), and ionic chemicals, such as calcium chloride (CaCl2).

A) Brittle is not a characteristic of most metals
Answer : The molar concentration of ethanol in the undiluted cognac is 8.44 M
Explanation :
Using neutralization law,
where,
= molar concentration of undiluted cognac = ?
= molar concentration of diluted cognac = 0.0844 M
= volume of undiluted cognac = 5.00 mL = 0.005 L
= volume of diluted cognac = 0.500 L
Now put all the given values in the above law, we get molar concentration of ethanol in the undiluted cognac.
Therefore, the molar concentration of ethanol in the undiluted cognac is 8.44 M
