The answer would be B the transfer of electrons from one atom to another
B is the correct answer! I learned this in class last week :)
Na is a cation (positive) and F is a anion (negative) this is an ionic bond. In a ionic bond the cation loses its valence electrons to give them to the anion. In this case Na will give its valence electron to F so F can complete its octet:)
Answer:
1.818x10²³ particles
Explanation:
Add the two atomic masses given to get 74.55 g.
Divide the number of grams given by the molar mass of KCl:
22.5g ÷ 74.55 = 0.302 mol
Multiply the moles by 6.022×10²³ particles
