Explanation: Outer shell electronic configuration for Group 18 is :
( have 8 electrons in the outer shell)
The electronic configurations for other groups are:
( have 1 electron in the outer shell}
( have 2 electrons in the outer shell)
( have 5 electrons in the outer shell)
( have 6 electrons in the outer shell)
( have 7 electrons in the outer shell)
Comparing the electron configurations of group 18 to other groups.
Group 18 has fully filled outer shell, that is 8 electrons in the outer shell, while others are partially filled.

Below is the solution:
pOH = - log (5.75 × 10^−4) = 3.24
<span>pH = 14 - 3.24 = 10.76</span>
Answer:
Below.
Explanation:
This is the combustion of the hydrocarbon propane.
C3H8 + 5O2 --> 3CO2 + 4H2O
physical, mathematical, and conceptual are the 3 types of models an example of a conceptual model is a model of our solar system or even a rocket a limitation of them is they are not realistic in scale but allow us see arrangements of things. mathematical models could be something like a formula graph charts ect we benefit from the visual steps however the downfall is there's lots of user error and a physical model is something like an atom model it allows to see the thing but it's physical states limits us
Atoms are the smallest form of the substance. examples of atoms are in elemental forms such as copper, helium, silver. Diatomic molecules are made up of identical atoms. Examples are I2.. F2 and Br2. Formula units are those compounds that are made up of two or more elements such as -No2, KMnO4,<span>C3H8, MgCl2, HgBr2, Ba(OH)2</span>
