Given four options, which of the following indicates the correct number of neutrons contained by Silicon-30? 8. Find the number of neutrons in Magnesium-25. 9. Choose the correct option that gives the number of neutrons in Neon-22.
The nucleus contains Z protons (same number as the atomic electrons), and A– Z neutrons, with A being the number of nucleons (protons and neutrons), known as the mass number. The nucleus is designated by where X is the name of the element; or simply AX, since for each element X,...

Protons, neutrons, and electrons are found in all atoms except the common form of hydrogen. The number of protons in an element’s nucleus determines its atomic number. The number of protons in a neutral atom is equal to the number of electrons in shells, which is the energy level around...
If you know that a nucleus has 6 protons and 6 neutrons, then its mass number is 12. If the nucleus has 6 protons and 7 neutrons, then its mass number is 13. Which best describes the relationship of magnesium and phosphorus? Which best describes the relationship of the elements?
At high temperatures, magnesium burns with a blinding white light Space technology often uses alloys that are too expensive for everyday use. An example is the propulsion systems used for keeping satellites in place. Some of these systems use alloys made of indium and another platinum metal, ...
