Answer: Option (1) is the correct answer.
Explanation:
Ionization energy is defined as the energy required to remove the most loosely bound electron from a neutral gaseous atom.
With increase in atomic size of the atom, there will be less force of attraction between the nucleus and the valence electrons of the atom. Hence, with lesser amount of energy the valence electrons can be removed.
When we move across a period then due to increase in force of attraction the size of atom decreases.
Thus, we can conclude that Phosphorus has a higher ionization energy than silicon because the outer orbitals of phosphorus are located closer to the nucleus than the outer orbitals of silicon.

No. i can go from my house to New York and back in a day since my final destination is the same as my beginning no work is done. if i go 20 ft from the house and stay i would have done more work. displacement is the key
The masses of the liquids are different making them have different densities
Answer:
8.10 hours.
Explanation:
You start with 500.0g.
After the first half-life, you have 250.0g.
After the second, you have 125.0g.
After the third, you have 62.50g.
Therefore, it takes three half-lives to decay to 62.50g.
Therefore, the elapsed time must be triple the length of one half-life.
24.3

=
8.10
, so it is 8.10 hours.
