Answer:
Atomic number=No. of protons=No. of electrons in ground state(unchanged atom)
Atomic number=13=No. of protons
Atomic mass=no. of protons+no. of neutrons=13+14=27
For isotope no. of proton=13(same atomic number but different mass number are isotopes)
no. of electrons=13
no. of neutrons=14+2=16

C. 6, 1, 0, -1/2
Explanation:
The four quantum numbers are:
- Principal quantum number (n): this represents the energy level in which an orbital is located.
- Azimuthal quantum number gives the shape of the orbitals in subshells accommodating the electrons.
- Magnetic quantum number gives the number of spatial orientations or degeneracy of the orbitals in the subshells.
- Spin quantum number describes the spinning of an electron in either clockwise or anticlockwise directions.
To know the electron with the highest energy, we use the principal quantum number values.
n values takes whole numbers i.e n = 1,2,3,4,5,6,7.............
The higher the value, the higher the energy level.
From the given quantum numbers, C has the highest energy levels.

Explanation:
Answer:
Solar power
Or in some cases, from heat from the sun. ... Solar energy is a renewable free source of energy that is sustainable and totally inexhaustible, unlike fossil fuels that are finite. It is also a non-polluting source of energy and it does not emit any greenhouse gases when producing electricity.
Explanation:
1- Molar solutions: based on number of moles of chemical in 1 litre of solution
2- Weight % solution: the weight of chemical divided by the total weight of the solution (chemical + water) and multiplied by 100.
