puzzle 5 who am i? identify each element. atomic numbers create code. a. nonmetal with atomic number of 53 and 5 energy levels b. unreactive gaseous element with 2 full energy levels c. silver colored, very reactive metal with 1 valence electron in period 4

puzzle 5 who am i? identify each element. atomic numbers create code. a. nonmetal with atomic number of 53 and 5 energy levels b. unreactive gaseous element with 2 full energy levels c. silver colored, very reactive metal with 1 valence electron in period 4

Answer

Explanation:

Step1: Identify element A

The element with atomic number 53 is iodine (I). It is a non - metal and has 5 energy levels.

Step2: Identify element B

The element with 2 full energy levels and is an unreactive gaseous element is neon (Ne). Neon has an atomic number of 10 and its outer shell is full, making it unreactive.

Step3: Identify element C

In period 4, a silver - colored, very reactive metal with 1 valence electron is potassium (K).

Answer:

A. Iodine (I) B. Neon (Ne) C. Potassium (K)
