Which of these is formed when a potassium ion is attracted to a chloride ion?OA. A large molecule
OB. A smaller ion
OC. A covalent bond
OD. An ionic compound

Answers

Answer 1
Answer:

Answer:D. An ionic compound

Explanation:

An ionic compound by a complete transfer of valence electrons from an atom of a metal to an atom of a non metal so that both can attain a stable duplet or octet structure of noble gases. Potassium has 19 electrons with one valence electron while chlorine has 17 electrons with 7 valence electrons. Potassium will transfer its valence electron to chlorine atom, resulting in potassium having one positive charge and chlorine have one negative charge with both attaining a noble octet structure of noble gases. The compound formed is an ionic compound because it involves a positively charged potassium ion and a negatively charged chloride ion.

Answers

Answer:

True

Explanation:

Carnivores that eat herbivores are called secondary consumers, and carnivores that eat other carnivores are called tertiary consumers. Animals and people who eat both animals and plants are called omnivores. Then there are decomposers (bacteria, fungi, and even some worms), which feed on decaying matter.
