The chemical properties of atoms primarily depend on their valence configuration. They seem to have a tendency to be noble-gas-like meaning losing, gaining, or sharing electrons so that they end up being surrounded by the same number of valence electrons as noble gas atoms (8, except He which has 2).. Culture of Poverty: . There are economic, social, and psychological traits that define the culture of poverty. Lewis specifically described the culture of poverty through a set of seventy interrelated traits. The culture of poverty can be explained as, “The way the poor adapted to their environment, the strategies they used to care with feelings of ’hopelessness and despair,’ a result of their ‘realization of the improbability of achieving success’ in class-stratified cities undergoing rapid technological change.” .
