PLEASE ASP HELP THIS WILL GIVE 50 POINT AND BRAINLIEST！！！！！! In introductory physics, a typical cavendish balance for measuring the gravitational constant G use metal masses 2.39kg and 16g whose center are separated by 6.81cm calculate the gravitation force between these forces, treating each as a point mass located at the center of the sphere.

gravitational constant =6.67259 × 10⁻¹¹N·m²/kg²

the answer is 2 electrons

Explanation:

The oxygen atom has atomic number 8, therefore its electronic configuration is

         1s² 2s² 2p⁴

the sublevel s has a capacity for 2 electrons so it is full

the sublevel p has capacity for 6 electrons, as in this atom it has only 4 electrons it needs two (2) more electrons to have its full capacity and to achieve maximum stability.

Consequently the answer is 2 electrons
