conclusion on elements and there types​

Answer 1

$\huge\underline{\underline{\mathfrak{\purple{AnSwEr}}}}$

On the basis of their chemical and physical properties, all elements can be divided into

$\large{\sf{\underline{\underline{ELemenTs:-}}}}$

✯Metals

✯Non metals

✯Metalloids

$\rule{300}{2}$

$\large{\sf{\underline{\underline{MeTals:-}}}}$

•They are malleable and ductile.

•They are good conductor of heat and electricity.

•They are strong and lustrous.

•They react with oxygen to form metal oxides and basic oxides.

•They react with water to form hydroxides.

•They react with dilute acids to displace hydrogen.

•example - Sodium, potassium, calcium etc.

$\rule{300}{2}$

$\large{\sf{\underline{\underline{Non-meTals:-}}}}$

•They are brittle.

•They are bad conductor of heat and electricity.

•They are non-lustrous and soft.

•They react with air to form non-metal oxides and acidic oxides .

•They doesn't react with water and dilute acids.

•example - sulphur, carbon

$\rule{300}{2}$

$\large{\sf{\underline{\underline{MetalloidS:-}}}}$

•They are intermediate properties of both metals and non -meTals.

•ex- Germanium
