In creating a covalent bond, it would be best to bind oxygen to ______. carbon (C) argon (Ar) magnesium (Mg) aluminum (Al)
Sedaia [141]

Answer: In creating a covalent bond, it would be best to bind oxygen to carbon (C ).

Covalent bonds result from electron-sharing between two atoms. One carbon atom combines with two oxygen atoms. Thus, the carbon dioxide molecule has two C=O bonds. Carbon dioxide is a very common covalent bond.

In the vertical columns of the periodic table, as the atomic numbers increase: The numbers of electron shells increase. The ioni
Kisachek [45]
The rule is number your table 1 2. 3 4 5 6 7 0 the number of shells increase as you go further up as it indicates the number of electrons on the outer shell e.g Argon will have 3 electrons on its outer shell hope this helps if not its then tighttt

Consider the reaction: AB As the reaction proceeds, the concentration of A drops from 0.625 M to 0.100 Min 11.6 seconds. What is
prisoha [69]

Answer:

0.045 M/s

Explanation:

Given:

Initial concentration of A = 0.625 M

Final concentration of A = 0.100 M

Total time taken for the change of concentration = 11.6 seconds

The average rate of reaction is calculated as:

= \frac{\textup{Change in concentration of A}}{\textup{Time taken for the change}}

on substituting the respective values, we get

= \frac{0.625-0.100}{\textup{11.6}}

or

The average rate of reaction = 0.045 M/s

If you can answer as many of these as possible that would be great, will give thanks, 5 stars, and brainliest :)
alexandr1967 [171]

Answer:

  1. The nucleus of the atom as suggested by "nuclear" chemistry.
  2. Radioactive element are generally very large due to both their high number of protons, neutrons, and electrons.
  3. An excessive amount of protons or neutrons.
  4. Periodic table, table O, and table N.
  5. Personal opinion question.
  6. The atomic number.
  7. It represents the number of protons, and can also represent the number of electrons in a neutral atom (an atom with no charge).
  8. Protons ---- element.
  9. Random, self-generated.
  10. Gamma radiation is the only thing on table O that is mass less. Close to being the same is Beta particles which have almost no mass.
  11. Neutrons and Gamma radiation.
  12. Gamma radiation.
  13. Electrons and Beta particles.
  14. To turn one element into the isotope of another. Yes, I believe it is aptly named because you are changing the identity of the element.
  15. The number of protons because they are what define the identity of an element.

Goodluck!
