If an atom has 15 electrons, how many electrons are in the n=1 energy level?
IRISSAK [1]

Answer:

In the n=1 energy level, the atom has 2 electrons

Explanation:

Electrons orbit the nucleus of an atom in multiple rings (energy levels). The first ring of the electron can only hold 2 electrons. After that, electrons are added to the second ring. Excluding the first ring, all other rings can hold a maximum of 8 electrons.

For example, Oxygen is an atom with 6 electrons. The first energy level contains 2 electrons, and the second energy level contains 4 electrons. The second energy level has room for up to 4 more electrons.

In your example of an atom with 15 electrons, there would be 2 electrons in the first ring, 8 electrons in the second ring, and 5 electrons in the third and final ring.

To summarize, all atoms have a first energy level containing 2 electrons, and all other energy levels can contain 8 electrons. This is true no matter the number of electrons.

 glucose solution of density 1050 kg/m3 is transferred from a collapsible bag through a tube and syringe into the vein of a pers
34kurt

Answer:

0.136 meter

Explanation:

The following equation will be used to solve this question -

P_{atm} + \frac{1}{2} (rho)v^2 + (rho)gh = P_{inject} + \frac{1}{2}(rho)v_{inject}^2 + (rho)gh_{injec}

P_{atm} -P_{injec} = 1400\frac{N}{m^{2} }

Velocity is zero.

Removing out the nullified terms from the above equation, we get -

(rho)gh = P_{injec}\\1050 * 9.8 * h = 1400\\h = \frac{1400}{1050*9.8} \\h = 0.136 meter

Hence,  top of the liquid in the bottle must be at a height of 0.136 meter.

If three times a number increased by 4, the result is -8
Dahasolnce [82]

Answer:

The original number is -4.

Explanation:

Let the original number be n.

Next, three times the number is equal to 3n.

Then, increased by 4 means 4 is added.

Hence, three times a number increased by 4 equals -8 is written in the equation form as shown below.

=>  3n + 4 = -8

=> 3n = -8 + (-4)

Since the number, 4, goes on the other side of the equal sign, the number positive 4 changes its sign and becomes negative 4, as shown above.

=> 3n = -8 -4

=> 3n = -12

=> n = -12/3

=> n = -4

Checking the above solution.

Three times the number is equal to 3 * (-4) = -12.

The above product when increased by 4 gives the equation as shown.

-12 + 4 = -8.

The result is -8.

This result is same as the result mentioned in the given question, -8.

Hence, the answer that -4 is the original number is correct.
