PCP, or angel dust, is a dangerous hallucinogen properly called phencyclidine.
Answer:
Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton
Explanation:
Based on periodic trends, the atom that has a larger ionization energy than calcium are Gallium, Germanium, Arsenic, Selenium, Bromine and Krypton.
Across the period, the ionization energy increases from left to right.
- Ionization energy is the energy required to remove the most loosely held electron within an atom.
- As you go from left to right, the ionization energy increases rapidly.
- The elements to the right of Ca will have a higher ionization energy compared to Ca.

2, because they are all a form of water.. but just in different states of matter depending on their form
The element symbol for oxygen<span> is O and its atomic number is 8. The mass numbers for oxygen must be 8 + 8 = 16; 8 + 9 = 17; 8 + 10 = 18</span>
