WebMar 22, 2024 · Some atoms have nearly eight electrons in their valence shell and can gain additional valence electrons until they have an octet. When these atoms gain electrons, they acquire a negative charge because they now possess more electrons than protons. Negatively charged ions are called anions. WebSecondary electrons are electrons generated as ionization products. They are called 'secondary' because they are generated by other radiation (the primary radiation). This …
WebMar 23, 2024 · Ionic charge: When the atom loses or gains one or more electrons, the electric charge is generated (and an ion is formed). This electric charge generated on the ion is known as Ionic charge. When atoms gain electron/s, the negatively charged ion is formed, and when the atoms lose electron/s, the positively charged ion is formed.
