When a reaction occurs between atoms with ground state electron configuration 1s2 2s1 and 1s2 2s2 2p5 the predominant type of bond formed is

Respuesta :

Space

Answer:

Ionic

Explanation:

Step 1: Define

1s²2s¹ is Lithium (Li)

1s²2s²2p⁵ is Chlorine (Cl)

Step 2: RxN

2Li (s) + Cl₂ (g) → 2LiCl (s)

Step 3: Identify

LiCl is a metal and a non-metal bonded together. Therefore, it will be an ionic bond. The Lithium would transfer it's electron to Chlorine (since it wants a full outer shell 0f 8 and it currently as 7) and form a salt.
