Question

d. group 3, period 16

1. below are 2 models for oxygen. determine the differences between the 2 models.

the first one have one circle and 6 small ones and the after one is a big one and has 2 circles

Explanation:

The first model has a single - circle nucleus with 6 small circles (presumably representing electrons) around it. The second model has a two - circle nucleus structure with multiple small circles (electrons) distributed in two electron - shell like regions. The main differences are in the nucleus structure (single - circle vs two - circle) and the electron - shell representation (no clear shell distinction in the first, two shells in the second).

Answer:

The first model has a single - circle nucleus with 6 electrons around it. The second model has a two - circle nucleus and two electron - shell regions with electrons distributed between them.
