Alkali Metals

Alkali metals are the soft shiny metals that comprise group 1 on the periodic table.

Do transition have higher melting point than alkaline and alkali metals?

User Avatar

Asked by Wiki User

Yes, transition metals generally have higher melting points compared to alkaline and alkali metals. This is because transition metals have a greater number of valence electrons and a stronger metallic bond, which requires more energy to break and transition from solid to liquid. In contrast, alkaline and alkali metals have fewer valence electrons and weaker metallic bonds, resulting in lower melting points.

Which statement about alkali metals are correct?

User Avatar

Asked by Wiki User

  1. Alkali metals belong to Group 1 of the periodic table.
  2. They are highly reactive and readily lose their outermost electron to form positive ions.
  3. Alkali metals have low melting and boiling points.
  4. They are soft and can be easily cut with a knife.
  5. Alkali metals include elements such as lithium, sodium, and potassium.

Why are alkali metals halogens and noble gases are three important groups in the periodic table?

User Avatar

Asked by Wiki User

Alkali metals, halogens, and noble gases are three important groups in the periodic table because they have unique properties and chemical behaviors that make them essential for various applications. Alkali metals are highly reactive and useful in batteries and other energy-related technologies. Halogens are highly reactive nonmetals used in disinfectants and as key components in industrial processes. Noble gases are chemically inert and find applications in lighting, cryogenics, and as fillers in electronic devices.

Why are alkali metals not found in pure form?

Asked by Wiki User

They are highly reactive metals, reacting with water (explosively) and air. In nature they simply would not last very long at all!

i don't know. but i am in chemestry and i need to know.

what i know so far is, that the are found in common substances.

if you are a chemestry teacher you should know! :)

plese get back to me by december 13th. i have a short exam then.

but i also know that They are unstable in air and in water (moisture).

Why are metallic bonds in an alkali metal relatively weak?

Asked by Wiki User

Alkali metals contribute only one valence electron

Are alkali metals active?

User Avatar

Asked by Wiki User

because they have outer electrons than can merge with other elements. all elements want to have full outer electron shells, and they only have a few outer electrons.

Why do halogens react so easily with Alkali Metals?

User Avatar

Asked by Wiki User

The electron configuration is why they react.

The Alkali metals have one electron in their outer shell and to complete their outer shell need 7 more electrons. They can give, take or share electrons with other atoms.

This is when the Halogens come in handy. The Halogens have 7 electrons in their outer shells, and need one more to complete the outer shell.

These can react very easily because they have both the perfect amounts to fill their outer shells and become compounds. Other atoms with other amounts to become atoms not ions needs another element to react with.

Hope this helps, Matt.

What is the similarities between alkali metals and alkaline earth metals?

User Avatar

Asked by Wiki User

AM are in group one and are very reactive, unstable, and has one electron in the outer shell, where as in AEM they are in group two and have 2 electrons in the outer shell.

How does the hardness of the alkaline earth metals compared to the hardness of alkali metals?

User Avatar

Asked by Wiki User

Transition state metals include a wide variety of metals; they include iron, gold, and mercury which all have strikingly different properties (hard, soft, and liquid, for example). Nonetheless, a comparison can be made between the transition state metals and the alkali and alkaline earth metals; transition state metals are not as chemically active (some transition state metals are actually inert, such as platinum).

Who are the two most powerful and important men in computer history?

Asked by Wiki User

A few years back, many would have said Bill Gates of Microsoft and Steve Jobs of Apple. However, Steve Jobs passed away and Bill Gates is no longer a part of Microsoft. Early in 2015, Bill Gates completely retired from Microsoft. He retired as CEO around 2000 and as Chairman in early 2015.

Which group do alkali metals bond with?

User Avatar

Asked by Wiki User

Alkali metals are electropositive so they want to react with halogens which are more electronegative.

Hydrogen is grouped with alkali metals because it?

Asked by Gloretta123

it has one electron in its outer energy level like all alkali metals

Is Cu an alkali metal?

User Avatar

Asked by Wiki User

Cu (Copper) is a transition metal

Is there any alkali metal in table salt?

User Avatar

Asked by Wiki User

Table salt is sodium chloride; sodium is a metalic element and chlorine is a non-metallic element.


Table salt is sodium (an explosive metal) combined with chlorine (a poisonous gas).

Sodium is Na; Chlorine is Cl. So table salt is NaCl.
This element is sodium (Na).
This element is sodium (Na).

Is Niobium an alkali metal?

User Avatar

Asked by Wiki User

No, Nb, atom no. 41, is in group 5 (period 5) of the transition metals (4d-trans.).

Alkali metals are in group 1, like Na and K.

Why are alkali metals so unstable?

User Avatar

Asked by Wiki User

They are very reactive.

They can react violently or explosively with water, usually catching fire soon after contact. They react with moisture and air to produce strong bases that can cause serious chemical burns.

The two most reactive of the metals, rubidium and cesium, burst into flames on contact with air.

Can Hydrogen make bond with alkali metals?

User Avatar

Asked by Wiki User

No, hydrogen is a nonmetal.

It is grouped with the alkali metals because it has a similar outer shell electron configuration as they do.

Hydrogen is something of an oddball among elements. It is rather unique, but share some characteristics with both the halogens and the alkali metals. When the periodic table is divided into groups (noble gasses, halogens, alkali metals, etc.) hydrogen is usually put in its own group.

How many valence electrons do the elements of alkali metals have?

User Avatar

Asked by Wiki User

Valence electrons are the electrons present in the outermost shell of an atom.

You can easily determine the number of valence electrons an atom can have by looking at its Group in the periodic table.

For example, atoms in Groups 1 and 2 have 1 and 2 valence electrons, respectively.

Atoms in Groups 13 and 18 have 3 and 8 valence electrons, respectively.

What is the largest element in the alkali metal?

User Avatar

Asked by Wiki User

No.

In fact lithium, one of the alkali metals, is the lightest metal.

In terms of molecular mass the heaviest metals are the actinides.

In terms of density the densest metals are osmium and iridium.

What type of bonds are typically formed by alkali metals?

Asked by Wiki User

Because between these two families of chemical elements a big difference of electronegativities exist.
