Why do electrons falling into different orbits give off characteristics wavelengths?​

Chemistry
1 answer:
Afina-wow [57]3 years ago
6 0

Explanation:

Because the difference in energy between orbits is different in different types of atoms, moving electrons between different orbits requires photons carrying different amounts of energy (different wavelengths).

How would the electron configuration of nitrogen change to make a stable configuration?
AnnZ [28]

The answers to the questions are as follows;

  1. It would gain three electrons
  2. The difference in their electronegativities.
  3. The elements have filled Valence levels
  4. potassium (K) with a 1+ charge
  5. ClO-

Question 1:

  • How would the electron configuration of nitrogen change to make a stable configuration?

Since Nitrogen has 5 Valence electrons, it needs 3 electrons to attain it's octet configuration. As such, it gains 3 electrons.

Question 2:

  • Which quantity determines how two atoms bond.

The quantity which determines how two atoms bond is The difference in their electronegativities.

Question 3:

  • Which statement best explains why the elements in Group 18 do not have electronegativity values.

This is because the elements have filled Valence levels.

Question 4:

  • Based on patterns in the periodic table, which ion has a stable valence electron configuration

The ion which has a stable Valence electron configuration is potassium (K) with a 1+ charge

Question 5;

  • Which chemical formula represents a polyatomic ion?

The chemical formula which represents a polyatomic ion is; ClO-

How many grams do 6.534e+24 molecules of phosphoric acid weigh?
fredd [130]

Answer:

1,063 grams H₃PO₄

Explanation:

To find the mass of phosphoric acid (H₃PO₄), you should (1) convert molecules to moles (via Avogadro's number) and then (2) convert moles to grams (via molar mass from periodic table).

Molar Mass (H₃PO₄): 3(1.008 g/mol) + 30.974 g/mol + 4(15.998 g/mol)

Molar Mas (H₃PO₄): 97.99 g/mol

6.534 x 10²⁴ molecules H₃PO₄                       1 mole                         97.99 g
---------------------------------------------  x  -------------------------------------  x  --------------
                                                            6.022 x 10²³ molecules          1 mole

= 1,063 grams H₃PO₄
