bond?
(1) H2 (3) O2
(2) N2 (4) Cl2
Answer: The correct answer is Option 2.
Explanation:
Covalent bond is defined as the b which is formed by the sharing of electrons between the atoms forming a bond.
Non-polar covalent bond is defined as the bond which is formed when there is no difference in electronegativity between the atoms. When atoms of the same element combine, it results in the formation of non-polar covalent bond. For Example: etc..
For the given options:
Hydrogen is the 1st element of the periodic table having electronic configuration
This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another hydrogen atom.
Nitrogen is the 7th element of the periodic table having electronic configuration
This element needs 3 electrons to attain stable electronic configuration and will form triple covalent bond with another nitrogen atom.
Oxygen is the 8th element of the periodic table having electronic configuration
This element needs 2 electrons to attain stable electronic configuration and will form double covalent bond with another oxygen atom.
Chlorine is the 17th element of the periodic table having electronic configuration
This element needs 1 electron to attain stable electronic configuration and will form single covalent bond with another chlorine atom.
Hence, the correct answer is Option 2.
germanium has 32 protons in its nucleus
True
Or False
True. In a chemical change, the same atoms are recombined into a new substances,
In a chemical change, also known as a chemical reaction, the atoms of the reactants are rearranged and recombined to form new substances with different chemical properties.
While the atoms themselves are not created or destroyed, their arrangement and bonding patterns change, resulting in the formation of new molecules or compounds. This process involves breaking and forming chemical bonds, leading to the creation of different substances with distinct properties from the original reactants.
