Using the words glass and grass, students practice using the G-blends at the start of a word. Students have to write a sentence using the word and think of three more words that start with the same blend.
Ions are electrically charged particles. Cations have a positive (+ ) charge. Anions have a negative (-) charge. Ions have a charge because electrons can be transferred. The charge is produced when atoms gain electrons (to form anions) or lose electrons (to form cations). Sodium, Na, is in group 1A. It loses one electron to form the sodium ion, Na1+. The charge is written after the symbol as a superscript.
An ion is positively or negatively charged due to the amount of electrons it has compared to the amount of protons it has. If an atom has MORE electrons, it will be a negative â¦ ion, or anion. If an atom has LESS electrons than protons, it will be positive, known as a cation. 16 people found this useful. Answered.
