Which of the following best defines an angle?
scoray [572]

Answer:

Third option

Step-by-step explanation:

The first definition is not as broad as it should be, therefore, while an angle does meet that criteria, it's not a general definition, hence, it is incorrect. The second one is incorrect as well because a parabola has a vertex, and it is certainly not an angle. This definition is not specific enough, so it will be eliminated. The last one is again, too specific. The third one is the best answer because it is broad enough while still being specific.

1/2

If you spilt one shape in half you will have two halves. The whole shape represents 100% and when you split it in half, into two pieces, you will have two 50% pieces.
Therefore the correct answer will be 1/2.

The first four ionization energies in kj/mol of a certain second- row element are 900, 1757, 14,849, and 21,007. what is the lik
ki77a [65]

Answer:<em> Berylium (Be)</em>

Step-by-step explanation:

The <em>first ionisation energy</em> is the energy required to remove one mole of the outermost electrons from one mole of gaseous atoms.

<em />

<em> Second, third, and fourth ionisation</em> energies are the energies required to remove the succesive mole of electrons of the same atoms

Successive ionisation energies are larger because, <em>once you have removed the first electron you get a positive ion</em>. Removing an electron (which is a negative charge) from a positive ion is more difficult than removing it from the neutral atom. And removing an electron from an ion with 2⁺ or  3⁺ charges is increasingly difficult.

When you find a large jump from one inoization energy to the succesive one you can predict that you are removing an electron from a closer to the nucleus orbital.

Berylium has atomic number 4. So, the number of electrons of the neutral atom is also 4. Hence, the electron configuration of beryllium is 1s² 2s².

From the given data, <em>the first four ionization energies in kJ/mol are 900, 1757, 14,849, and 21,007</em>.

From that you can calculate the following changes in the ionization energies:

  • From first to second: 1,757 kJ/mol - 900 kJ/mol = 857 kJ/mol
  • From second to third: 14,849 kJ/mol - 1,757kJ/mol = 13,092 kJ/mol
  • From third to fourth: 21,007 kJ/mol - 14,849 kJ/mol = 6,158 kJ/mol

And now you can see that there is a larger jump in the energy, a greater change, required to remove the third electron.

That is explained because the first and second electron are removed from the orbital 2s while the third electron has to be removed from the orbital 1s which is closer to the nucleus. This third electron is more strongly attracted by the nucleus and substantially  more energy is required to accomplish this work.
