Question

2. Identify the ion, the number of protons, the num A. 42 ? + 3 er or protons, the number of electrons, and give the IUPAC name. 1173 B. 85?-1 C. s2 ? -2

Answer 1

Atomic No = 47 Silver has atomic No 47 * No of protons = Atomic No = 47 - No of electrons - Atomic No & charge = 47 - 3 ctrons = 44 charge +3 means 1o Aq3+ 3 é is lost from the Element I UPAC Name Silver Atomic No =85 I The atomic No of Astatine Tellurim is 85 * - No of protons - Atomic No = 85] No of electrons - Atomic No I charge No of electrone = 85t1 = 86 No of electrons = 86 € Ton - TASI TUPAC Name - Astatine

Atomic No - 52 The Atomic No of Tellurium is 52 & No of protonis = Atomic No =52) - No of electrons = No of electrone = Atomic wo I charge 52+2 = 54 I Ton Tee- TUPAC Name - Tellurium
