There are at least two major approaches to understanding cognitive change during adolescence. One is the constructivist view of cognitive development. Based on the work of Piaget, it takes a quantitative, state-theory approach, hypothesizing that adolescents' cognitive improvement is relatively sudden and drastic.
Atoms bond to form molecules. Two or more atoms may bond with each other to form a molecule. When two hydrogens and an oxygen share electrons via covalent bonds, a water molecule is formed. Chemical reactions occur when two or more atoms bond together to form molecules or when bonded atoms are broken apart. Describe the properties of chemical reactions and compounds. Atoms form chemical bonds with other atoms thereby obtaining the electrons they need to attain a stable electron configuration.
A chemical bond is formed when atoms are held together by attractive forces. This attraction occurs when electrons are shared between atoms, or when electrons are exchanged between the atoms that are involved in the bond.efinition 1: A chemical bond is the physical process that causes atoms and molecules to be attracted to each other and held together in more stable chemical compounds. The type of bond that is formed depends on the elements that are involved.
