<u>Explanation:</u>
- A mammogram is an X-ray of the breast. Mammograms are commonly used to screen for breast cancer.
- Radio-tracking technology assists in determining exactly where an animal is located at any instant in time and frequently what that animal is performing! Utilizing the data collected from tracking devices, scientists can conclude the day-to-day activities of an animal, the size of an animal's place range, what other animals share an animal's range and the types of habitats an animal practices.
- Gamma-rays are the common energetic form of light and are generated by the most heated regions of the universe. Gamma rays are provided by such extreme events as supernova explosions or the elimination of atoms and by less exciting events, such as the breakdown of radioactive material in space.
Answer:
Germanium.
Explanation:
In a neutral atom: the number of protons = the number of electrons.
Atomic number of a neutral atom = number of electrons = number of protons.
- Phosphorous is an element with atomic number 15 and thus contains 15 electrons and 15 protons.
- Cobalt is an element with atomic number 27 and thus contains 27 electrons and 27 protons.
- <em>Germanium is an element with atomic number 32 and thus contains 32 electrons and 32 protons.</em>
<em></em>
- Sulfur is an element with atomic number 16 and thus contains 16 electrons and 16 protons.
