The question is incomplete, here is the complete question:

Give the charge and full ground-state electron configuration of the monatomic ion most likely to be formed by each element: (a) P, (b)  Mg,  (c) Se

<u>Answer:</u>

<u>For a:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^6

<u>For b:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^6

<u>For c:</u> The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^64s^23d^{10}4p^6

<u>Explanation:</u>

An ion is formed when a neutral atom looses or gains electrons.

  • When an atom looses electrons, it results in the formation of positive ion known as cation.
  • When an atom gains electrons, it results in the formation of negative ion known as anion.

For the given elements:

(a) Phosphorus

This is the 15th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^3

This element will gain 3 electrons to form P^{3-} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^6

(b) Magnesium

This is the 12th element of the periodic table having electronic configuration of 1s^22s^22p^63s^2

This element will loose 2 electrons to form Mg^{2+} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^6

(c) Selenium

This is the 34th element of the periodic table having electronic configuration of 1s^22s^22p^63s^23p^64s^23d^{10}4p^4

This element will gain 2 electrons to form Se^{2-} ion

The electronic configuration of the monoatomic ion formed is 1s^22s^22p^63s^23p^64s^23d^{10}4p^6

A force of 100 newtons is applied to a box at an angle of 36º with the horizontal. If the mass of the box is 25 kilograms, what
notka56 [123]

Answer:

a_x=4.944m/s^2

Explanation:

Hello,

Based on the acting force that is applied horizontally, one can propose the following equation based on Newton's laws:

F=ma

Nevertheless, since we've got a angled force, it becomes:

F=macos\theta

In this case, cos\theta accounts for the formed angle, so the horizontal acceleration turns out into:

a_x=\frac{F}{mcos\theta}=\frac{100kg*\frac{m}{s^2} }{25kgcos(36^0)}=4.944m/s^2

Best regads.

5. Can you determine the number of neutrons in the nucleus of an atom by looking at the element's average atomic mass and the at
Shkiper50 [21]

Answer:

No you can't

Explanation:

The atomic number is the amount of protons in element's nucleus, that's one reason why. The second reason is that the atomic mass is protons and neutrons combined, their estimated value, which doesn't show how much neutrons are in an element. It does show combined, but not specifically neutrons

A solution is prepared by dissolving 27.7 g of cacl2 in 375 g of water. the density of the resulting solution is 1.05 g/ml. the
bagirrra123 [75]
The answer is 6.88.
Solution:
We can calculate for the percent composition of CaCl2 by mass by dividing the mass of the CaCl2 solute by the mass of the solution and then multiply by 100. The total mass of the resulting solution is the sum of the mass of CaCl2 solute and the mass of water solvent. Therefore, the percent composition of CaCl2 by mass is 
     % by mass = (mass of the solute / mass of the solution)*100 
                        = mass of solute / (mass of the solute + mass of the solvent)*100
                        = (27.7 g CaCl2 / 27.7g + 375g) * 100 
                        = 6.88
