Question

NAME 2 ELEMENTS WHICH IS LIQUID AT ROOM TEMPERATURE.

Answer 1

Answer:

Bromine (Br, a halogen and non-metal) and Mercury (Hg, a metal) are two elements that are liquid at room temperature.

Explanation:

Br and Hg are liquid at S.T.P whereas some other elements such as Ga (Gallium), Cs (Caesium), Fr (Francium), and Rb (Rubidium) are liquid at just above room temperature.

These elements are liquid at room temperature because their electrons are not tightly bound to the atomic nucleus. In Hg, electrons are not shared between the atoms which is the main reason for its liquid state at room temperature. However, Br is liquid at room temperature because of the high intermolecular forces which prevent the vaporization.

Answer 2

Bromine (Br), a halogen and non-metal and Mercury (Hg), a metal are two elements that are liquid at room temperature.

Explanation:

• At S.T.P Br and Hg are liquid  whereas some other elements such as Ga (Gallium), Cs (Cesium), Fr (Francium), and Rb (Rubidium) are liquid at just above room temperature.
• These two elements are liquid at room temperature.
• In these elements the electrons found are not tightly bound to the atomic nucleus.
• In Hg,the electrons are not shared between the atoms but is not in shairing mode due to which is it is in liquid state at room temperature.
• Br is liquid at room temperature due to high intermolecular forces.
• This intermolecular forces prevents the vaporization process.
