Based on its location on the periodic table, how many electrons does oxygen have in its outer energy level?
2 answers:
Answer:
The number of electrons in the outer energy level of oxygen is 6.
Explanation:
Oxygen is present in the group 16 of the periodic table. The electronic configuration of group 16 element is . The number of electrons in outer energy level of group 16 element is always found to be 6.
The addition of the number of the electrons present in the valence shell orbitals of oxygen will give the total number of electrons present in the outer energy level.
The number of electron in the outer energy level of oxygen is (2 + 4) = 6.

Answer:
3m/s²
Explanation:
Given parameters:
Mass of object = 3.2kg
Force to the right = 16.3N
Force to the left = 6.7N
Unknown:
Acceleration of the object = ?
Solution:
To solve this problem, we use newtons second law of motion;
Net force = mass x acceleration
Net force on object = Force to the right - Force to the left
Net force = 16.3N - 6.7N = 9.6N
So;
9.6 = 3.2 x a
a = = 3m/s²
