For changes of state “Solidification” and “fusion”and “Condensation” and “vaporization” to take place energy must be added to or removed from a substance. Give the general name for this type of energy and state what happens to the temperature during these processes.

The answer is true for your question.

If a hydrogen atom is neutral, it must also have  one electron. an oxygen atom (o) has an atomic number of eight (8). this means a neutral oxygen atom has eight protons and eight electrons. the element actium (ac) has an atomic number of 89, so it has 89 protons and 89 electrons in a neutral atom
