Answer:
B
Explanation:
A chemical bond is formed when there is a transfer or sharing of electrons. When there is a transfer, what we have is that the electrons completely leave the outermost shell of an atom, usually metal to the outermost shell of another atom, usually a nonmetal. This particularly alters the electronic configuration of these atoms. This is ionic or electrovalent bonding
Now, electron sharing is also another way of chemical bond formation. Electrons might be shared between two atoms in a case principally known as covalent bonding. The electrons here are controlled by the 2 nuclei
Answer:
hi
Explanation:
chemistry the branch of science that deals with the identification of the substances of which matter is composed; the investigation of their properties and the ways in which they interact, combine, and change; and the use of these processes to form new substances.
Science the intellectual and practical activity encompassing the systematic study of the structure and behaviour of the physical and natural world through observation and experiment.
