Alkali Metals

The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.

These are characteristics of alkaline earth metals, such as calcium and magnesium. They have tightly packed metallic lattices, making them denser and harder than alkali metals. Their higher melting points and lower reactivity compared to alkali metals can be attributed to their lower atomic size and increased nuclear charge.

Alkali metals have 1 valence electron.

Francium is the most reactive chemical element; unfortunately is extremely rare and currently not available for chemical experiments. Also is very radioactive.

Lithium, Sodium, Potassium, Rubidium, Caesium, Francium

Alkali Metal + Water ------> Alkali Hydroxide + Hydrogen Alkali Metal Oxide + Water ------> Alkali Hydroxide + Water

Example: ================

Sodium + Water ------> Sodium Hydroxide + Hydrogen 2 Na + 2 H2O --------> 2 NaOH + H2

are highly reactive and readily form compounds with other elements due to their tendency to lose one electron, resulting in a stable electron configuration. This makes them too unstable to exist in their pure form in nature.

Chlorine has a high electronegativity, meaning it has a strong tendency to attract electrons. This property makes it likely to form a compound with an alkali metal through ionic bonding, where the alkali metal loses an electron to chlorine to achieve a more stable electron configuration.

No, aluminum is not an alkali metal. Alkali metals are the group of elements in the periodic table that include lithium, sodium, potassium, rubidium, cesium, and francium. Aluminum belongs to a different group of elements called the post-transition metals.

An alkali metal is any Group 1 metallic elements: lithium, sodium, potassium, rubidium, cesium and francium; all are strongly reative, soft low density metals. Which means if they come in contact with a halogen it can cause a vigorous reaction.

it is about the metal cs. it is inn the 6th period.

Yes, francium is an alkali metal; the group contain lithium, sodium, potassium, caesium, rubidium and francium.

They are all soft, highly reactive metals with low melting points.

They react vigorously or violently with water, producing hydrogen gas and the corresponding hydroxide.

They form 1+ ions and their compounds are water soluble.

1.Both are differ in valency shell electrons

2.I-A are monovalent and II-A are divalent

3.I-A is more reactive then the II-A group .

4.I-A have more electro positive character and II-A have less electro positive character than the

I-A group .

5.I-A have less ionization energy and II-A have high ionization energy than the I-A .

6.I-A have very less electro negativity than the II-A group elements.

7.I-A is soluble in water and II-A is insoluble in water .

8.I-A metals are does not react directly with nitrogen but II-A react with nitrogen directly.

9.I-A group elements are strong reducing agents than the II-A group elements.

10.The oxidation values are differ.

11.I-A obtained in solid state but II-A group in solution state

12.Decomposes on heating I-A give only oxygen but II-A group liberates both oxygen and nitrogen .

When alkali metals like sodium or potassium are exposed to water, a highly exothermic reaction occurs, which means it releases a large amount of heat. This heat generated by the reaction ignites the hydrogen gas produced, resulting in a flame or explosion. The reaction is so violent because the alkali metals readily donate electrons to water, releasing hydrogen gas and forming hydroxide ions.

Yes. To much intake can be harmfull but elevated potassium levels in the body can cause irregular heart beats, cardiac arrhythmia, tachycardia and even heart attack. It depends on the kidney function as well. Excess boday potassium in the body is passed out through urine. But kidney failure or a underfunctioning kidney can cause excess potassium to bould up and cause heart attack. Elevated potassium levels is called Hyperkalemia and low potassium levels are called Hyporkalemia. Both are dangerous.

The alkali metal family consists of the elements lithium, sodium, potassium, rubidium, cesium, and francium. These elements share similar chemical properties, including being highly reactive and forming alkaline solutions when they react with water.

In order of reaction strength:

Lithium

Sodium

Potassium

Rubidium

Cesium

Francium

Look in related links for a video demonstrating the reactions of different alkali metals mixed with water.

Alkali metals are found in Group 1 of the periodic table.

Their factors include being soft enough to cut and have low melting points and densities too. They all react viciously with water, releasing hydrogen and forming hydroxides. They stain rapidly even in dry air. They are never found un-combined in nature. Decreasing down the periodic table (increasing atomic number) the alkali metals are: lithium,

sodium, potassium, rubidium, caesium and francium.

The alkali metals are the elements Lithium, Sodium, Potassium,

Rubidium, Caesium and Francium. They are grouped together

because they all behave similarly (except with different strengths) and together form Group 1 of the Periodic Table.

They are in fact very soft metals that can be cut with a knife. They do not occur naturally because they react readily with air and moisture and so need to be stored under oil.

One of the signature reactions of alkali metals is their reaction with water to form alkaline solutions, for example sodium reacts with water to form sodium

hydroxide.

The reaction of alkali metals with water is pretty vigorous and as we see in the video clip as we go down Group 1 of the Periodic Table, from Lithium to Caesium, things get more and more frightening.

Lithium is used to make

rechargeable batteries and

lightweight alloys. Some of its

compounds are used as mood

stabilising drugs.

Sodium (vapour) is used in bright yellow street lights. It is also used as a heat transfer agent in some types nuclear reactor. Sodium salts are

essential to life - ordinary table salt is sodium chloride.

Potassium salts are used as

fertilisers, such as potassium

chloride which used to be called chloride of potash. Potassium nitrate is one of the components of

gunpowder. Potassium salts are also essential to life.

Rubidium and Caesium have a

number of specialist uses such as the use of Caesium in atomic clocks that are very accurate and Rubidium, used in specialist glasses. Francium is an extremely rare metal mainly

because it readily undergoes

radioactive decay with a half life of less than 22

minutes.

Due to the lack and short half life, there are not many uses for francium other than scientific research.

Proven from my research I can tell that there are many benefits we can consider when using alkali metals for example: it helps people with

medicine issues, can contribute to batteries in a mobile and is a factor of glass for lenses or tubes inside TV's. Lithium is the main source and can be used for all sorts of

technology.

I hope the above information helps you

Hydrogen is grouped with the alkali metals because it has similar properties to Group 1 elements, such as forming ions with a +1 charge and being highly reactive. However, hydrogen is often considered separately due to its unique properties, such as variability in oxidation states.

Francium is the least reactive metal in the alkali metal group. This is due to its large atomic size and low electronegativity, which result in weaker attraction to electrons and less reactivity compared to other alkali metals. However, francium is extremely rare and radioactive, making it difficult to study its chemical properties.

Alkali metals typically bond with elements from Group 17, known as the halogens. This is because alkali metals have one electron to donate, while halogens have one electron missing to complete their outer electron shell, creating an opportunity for a strong ionic bond to form between the two groups.

Alkali metals are more reactive as they are in group 1 and therefore has only one valence electron. With only one valence electron, its easy for them to achieve inert configuration/ noble gas configuration, which makes them so reactive.
