Question

What bond holds the atoms of the elements in groups 1 and 2 of the periodic table? ​

Answer 1

Answer:

A covalent bond is the force of attraction that holds together two atoms that share a pair of valence electrons. Covalent bonds form only between atoms of nonmetals. The two atoms that are held together in a covalent bond may be atoms of the same element or different elements.

Answer 2

The atoms of the elements in groups 1 and 2 of the periodic table are held together by metallic bonds.

• Group 1 in the periodic table consists of alkali metals.
• Group 2 in the periodic table consists of alkaline earth metals.
• Metallic bonds forms between metals.
• This chemical bond is formed due to the electrostatic attraction of positive metal ions and conduction electrons.
• In metals, the sharing of free electrons among positive ions results in this bond.
• Properties like strength, ductility, resistivity, conductivity, etc. exhibited by group 1 and 2 elements are due to the metallic bonds.
