Charge of an atom: Each atom has an equal number of protons (+1 charge) and electrons (-1 charge), therefore the overall charge of the atom is 0, or 'neutral'. If one or more electrons are removed then the particle would be positively charged and if one or more additional electrons ...
An atom that has more protons than electrons is called a cation. Ions are charged atoms or combinations of atoms. When an atom loses one or more...Become a member and unlock all Study Answers Try it risk-free for 30 days Try it risk-free Ask a question Our experts can answer your...
- The third shell has 7 electrons. - Therefore, the total number of electrons is calculated as: 2+8+7=17 electrons 3. Determine Atomic Number: - For a neutral atom, the number of electrons is equal to the number of protons. - Thus, the atomic number, which is the number of prot...

Since each shell has a definite number of orbitals and each orbital occupies an electron pair, each shell has a maximum electron count (maximum occupancy). Electrons in an atom are identified using quantum numbers. Answer and Explanation: The allowed values of l, ml ...
An atom has three types of very tiny particles called protons, neutrons and electrons. The center of an atom is called the nucleus, and it is made up of protons and neutrons. The electrons in an atom fly around and above the nucleus in a cloud-like formation. The protons have a positiv...
A Magnesium Ion typically refers to Mg^2+, formed by losing two electrons. In Magnesium chloride, each Magnesium atom forms a Mg^2+ ion. 11 Magnesium Atom The atomic number of a Magnesium Atom is 12. A Magnesium atom has 12 protons in its nucleus. 11 Magnesium Ion Often found in ionic...
