What group contains a solid ,liquid and gas at room temperature

group 7

Explanation:

fluorine and chlorine are gases at room temp

bromine is liquid at room temp

iodine and astatine are solid at room temp

they are all in group 7

Group 17 or VIIA which consists of Halogens have elements existing in solid, liquid and gas at room temperature (20 degree celcius).

Explanation:

Fluorine, Chlorine, bromine, Iodine and Astatine are the halogens we know.

At room temperature,

Fluorine and chlorine are gases,

Bromine is a liquid and  

Iodine and Astatine are solids.

Halogens are called as Salt producer.

They are diatomic elements except Astatine with a subscript 2 which represents a molecule of halogen is comprised of two halogen atoms

The general electronic configuration of halogen is

The elements present in the same group will have same number of valence electrons (outer shell electrons)

For example  

Fluorine, Chlorine, Bromine are all present in the same Group

The electronic configurations  are  

Hence all these elements have similar chemical properties since it depends on the electrons present in an element.

explanation: well the force of an object when it lands sitting on the ground isthe force of a wide rage of situations crucial to physics? ; ( i 'm trying my best to alot but im not smart enofe you for giving me this chance though! 3(

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .
