What properties do Group 1 metals have?

Alkali metals are soft solids and can be easily cut. Alkali metals have low densities as compared to heavy metals such as iron and copper. Alkali metals are good conductors of heat and electricity. Alkali metals have low melting and boiling points as compared to heavy metals such as copper and iron.

What are the characteristics of groups of periodic table?

Valence electrons, valency, atomic size, ionization energy, metallic character, electron-positivity, electron-negativity and reactivity are the characteristics of groups. The atomic radius of the element (i.e. atomic size) lying in a group increases as we go up from top to bottom in a group.

Which property is characteristic of the elements in group 1A?

They have one valence electron. They form a +1 cation and ionic bonds. They are soft and bendable. They are reactive.

What are the uses of Group 1 elements?

Uses of alkali metals Lithium is often used in batteries, and lithium oxide can help process silica. Lithium can also be used to make lubricating greases, air treatment, and aluminum production.

What are the trends of Group 1?

Explaining the trend The reactivity of group 1 elements increases as you go down the group because: the atoms become larger. the outer electron becomes further from the nucleus. the force of attraction between the nucleus and the outer electron decreases.

Why are Group 1 metals called alkali metals?

The alkali metals are so named because when they react with water they form alkalies. Alkalies are hydroxide compounds of these elements, such as sodium hydroxide and potassium hydroxide. Alkalies are very strong bases that are caustic.

What are the physical and chemical properties of Group 1 elements?

The alkali metals are a group of chemical elements in the periodic table with the following physical and chemical properties:

• shiny.
• soft.
• silvery.
• highly reactive at standard temperature and pressure.
• readily lose their outermost electron to form cations with a charge of +1.

What is group 1 on the periodic table called?

The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).

What are the Group 1 elements used for?

alkali metalAny of the soft, light, reactive metals of Group 1 of the periodic table; lithium, sodium, potassium, rubidium, cesium, and francium. lyeA strong caustic alkaline solution of potassium or sodium salts, obtained by leaching wood ashes. It is much used in making soap as well as in biodiesel.
