Why alkali metals have low ionization energy?

Ionization energy is the energy required to remove an electron from an atom or ion. Low ionization energy indicates that it takes less energy to remove an electron from the atom. The alkali metals are in Group I on the Periodic Table. This indicates that their atoms have only one electron (out of a possible eight) in their outermost energy level. Therefore it takes less energy to remove the single outermost electron.

Moving across a period on the Periodic Table, ionization energies increase because there are more and more electrons in the outermost energy level, requiring more energy to remove an electron.

Describe the trend observed in ionization energy across a period and down a group?

Across a period, first ionization energy increases. However, when going down a group, first ionization energy generally decreases.

As you go down a group, atoms hove more total electrons so they don't really care that much about their outermost ones.

How many valence electrons do alkali metal family members have?

The key to this answer is the phrase "valence electrons". Alkali metals are in the first column of the periodic table and include elements such as Lithium, Sodium and Potassium. These elements typically lose ONE electron when they participate in a chemical reaction, therefore they have ONE valence electron.

What are some examples of ferrous metals?

The word "Ferrous" derives from the Latin ferum meaning iron, so any metal containing iron is a ferrous metal.

If Ferrous metals contain iron then this means that any metal that contains iron and is magnetic is a ferrous metals. Some examples of Ferrous metals are steel, stainless steel, and all types of iron such as wrought iron, cast iron, pig iron and some others. . . carbon steel . .mild steel . .

Why are alkali metals called alkali metals?

When alkali metals react with water they produce an alkali (basic) solution.

No because they form basic oxides and they neutralise acids

Why do halogens become less reactive down the column?

It's easier for halogens to gain an electron than to let seven electrons go to become reactive.

---------------------------------------------------------------------------

The further down the column you go the more electron shells in between the nucleus and the outside shell there are and so it has less 'pulling power' to grab that extra electron.

What happens to the melting points of the alkali metal as you go down group 1?

The melting point increases. Francium is a "hot-spot" on the periodic table. It is the most metallic substance and therefore has the highest melting point.

Explain why alkali metals are not found in free state in nature?

Alkali Metals belong to group 1 of periodic table. They have one electron in last or valence shell and are highly electropositive and have low value of Ionisation enthalpy. So the removal of last electron to form a cation(positively charged ion) is very easy and needs less energy as compared to other elements. As a result of this Alkali metals are highly reactive and readily form ionic compounds. Due to this they react with other elements or compounds and form ionic compound. Hence, they are found in their compounds and not in free state.

I am not really an alkali metal but since i have only 1 electron i behave like them?

The answer is hydrogen. Hydrogen is in the alkali metal family. It has 1 electron and behaves like them. This is found on the periodic table of elements.

Why is there a pattern in melting point for alkali metals?

if you search the periodic table and find you can see the numeric value numbers of 1 to 8 then shortly you will see the radius will increase vigourusly showing the bottom and top number at any one time then that is how to get the radius separated from the core nucleus
