Answer:

This atom has 1 valence electron

Explanation:

Step 1: Data given

The ionization energy for the following element is:

I 496

II 4562

III 6912

IV 9544

V 13353

The element that has this ionization energy is sodium (Na)

Sodium has 11 electrons:

2 electrons on the first shell

8 electrons on the second shell

1 electron on the outer shell = 1 valence electron

This atom has 1 valence electron

tankabanditka [31]
The Earth, Mars or Jupiter should be denser than the Sun. Density is defined by mass and volume — components of object or matter. Although the sun is huge, it’s component is made up of mostly gas (hydrogen and helium). While Earth, though smaller than the Sun, contains heavier elements such as iron, sulfur, rocks, sediments, granite, basalt and water. Mars (composed of rocks and nutrients) and Jupiter (contains gases and compounds) as well are denser when compared to the Sun’s density. Referencing to our basic understanding of matter: solid and liquid should be heavier than gas.

Carbon is the main constituent of hydrocarbons. Why some are called unsaturated hydrocarbon? Briefly describe.
maw [93]

Some hydrocarbons are regarded as unsaturated because they contain double or triple bonds between adjacent carbon atoms.

<h3>What are hydrocarbons?</h3>

Hydrocarbons are any organic compounds that contain hydrogen and carbon in its structure.

Hydrocarbons can be grouped into the following based on whether they contain single or double bonds:

  1. Saturated hydrocarbons - contain only single bonds e.g. alkanes
  2. Unsaturated hydrocarbons - contain double and triple bonds e.g. alkenes

Therefore, it can be said that some hydrocarbons are regarded as unsaturated because they contain double or triple bonds between adjacent carbon atoms.
