Chemistry
1 answer:
Goshia [24]2 years ago
3 0

Answer:

Option B

Explanation:

For the problem in question 12, option B is the correct choice. It rightly expresses how electrons will fill the third energy level of aluminum.

Aluminum is an element with 13 electrons. It has 3 energy levels.

 The shell notation is given as 2 8 3

 Sublevel notation  = 1s² 2s² 2p⁶ 3s² 3p¹

 The third energy level is given as 3s² 3p¹

  We can represent it as:  ⇅     ↑

                                            3s²   3p¹

An ion with six protons, seven neutrons, and a charge of 2+ has an atomic number of ________.
Varvara68 [4.7K]
There are some standard numbers that help us describe the structure of an atom and help us categorize them. Those are the atomic number, the mass number and the numbers of electrons in an atom (or ion). Atoms are electrically neutral, hence they have the same number of protons as electrons. If an atom has a charge and has thus become an ion, it is because electrons joined it or left. For example in this case, since the ion has +2 charge, 2 electrons left it and thus the ion has 4 electrons (2 electrons less than its protons). The mass number is the sum of the protons and neutrons of an atom (that are in the nucleus). In this case, this yields a mass number of 13 for this ion. The atomic number of an atom (or ion) is the total number of protons in the nucleus. Protons do not leave the nucleus except for radioactive reactions and thus the atomic number of an atom (or ion) does not change in chemical reactions. In this case, the ion has an atomic number of 6.

30 POINTS PLEASE HELP ASAP
lina2011 [118]

Hello!

We have the following data:

f (radiation frequency) = 3.0*10^{19}\:Hz

v (speed of light) = 3.0*10^8\:m/s

λ (wavelength) = ? (in m)

Let's find the wavelength, let's see:

f = \dfrac{v}{\lambda}

3.0*10^{19} = \dfrac{3.0*10^8}{\lambda}

\lambda = \dfrac{3.0*10^8}{3.0*10^{19}}

\boxed{\boxed{\lambda = 1*10^{-11}\:m}}\Longleftarrow(wavelenght)\end{array}}\qquad\checkmark

I Hope this helps, greetings ... DexteR! =)
