Answer 1

Answer:1) What is meant by a chemical bond ??

2) What is the number of chemical bonds that an atom of an element forms called ??

3) What are the two important types of chemical bonds ??

Explanation:

(1) A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.

(2) Key Takeaways. A covalent bond is formed between two atoms by sharing electrons. The number of bonds an element forms in a covalent compound is determined by the number of electrons it needs to reach octet. Hydrogen is an exception to the octet rule

(3) Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds.

Answer 2

Answer:

• 1) A chemical bond is a lasting attraction between atoms, ions or molecules that enables the formation of chemical compounds. The bond may result from the electrostatic force of attraction between oppositely charged ions as in ionic bonds or through the sharing of electrons as in covalent bonds.
• 2) The number of bonds that an atom can form can often be predicted from the number of electrons needed to reach an octet (eight valence electrons).
• 3) Chemical bonds include covalent, polar covalent, and ionic bonds. Atoms with relatively similar electronegativities share electrons between them and are connected by covalent bonds
