Question

look at the model. then, choose the best answers. 12 choose the best answer. what type of model is this? cloud plum pudding bohr rutherford 13. choose the best answer. how many energy levels does boron have? 1 2 3 4

Explanation:

1. The Bohr model depicts electrons in fixed - orbits around the nucleus, which is what the given model shows. The cloud model represents the probability of finding an electron, the plum - pudding model has electrons embedded in a positive sphere, and the Rutherford model just shows a nucleus with electrons around it without defined orbits like Bohr's.
2. By looking at the model, we can count the number of concentric circles representing energy levels. Boron has 2 energy levels filled with electrons as shown in the model.

Answer:

1. Bohr
2. 2
