Explanation:
Percentage Yield = (175/250) * 100% = 70.0%.
Basically, the arrangement of electrons in electronic configuration follows three principles:
1. Aufbau Principle
You start from the highest energy level to the lowest. The arrangement is: <span>1s<2s<2p<3s<3p<4s<3d<4p<5s<4d<5p<6s<4f<5d<6p<7s<5f<6d<7p.
2. Hund's Rule
Each box in the configuration can hold up to 2 electrons. This rule tells you to fill all boxes of one particular subshell with 1 electron first, before double occupying them.
3. Pauli's Exclusion Principle
This rule tells you that the two electrons in a box shall always have opposite spins, represented by one half-arrow up and one half-arrow down.</span>
Answer:
Carbon (C)
Explanation:
Carbon is the only nonmetal there and covalent bonds happen between two nonmetal atoms
Answer:
Explanation:
This took some time, but I hope my answers are correct
The eletron pairs repel each other in a tetrahedral shape.
