The climate of the continental united states is generally 1. tropical 2. temperate 3. arctic 4. highland

Identify one disadvantage to each of the following models of electron configuration: -dot structures -arrow and line diagrams -written electron configurations type in your answer below. (answer) -dot structures do not show the distribution of electrons in orbitals and take up a lot of space. -arrow and line diagrams take up a lot of space and make it difficult to count electrons. -written configurations make it easy to lose count of electrons and do not show the distribution of electrons in orbitals.

The diagram below shows the different phase transitions that occur in matter. which arrow represents the transition in which dew is formed?
