Why does an atom of sodium have a larger atomic radius than an atom of chlorine?

1 answer:

3 0

Even though sodium and chlorine belong to the same period, Sodium has a larger atomic radius than chlorine. This is because of the difference in the number of electrons on the valence shell. Because chlorine has seven valence electrons then these electrons are more tightly held by the nucleus than in the case of Sodium which only has one electron on the last shell thus the valence shell is loosely held by the nucleus.

Ammonia is oxidized with air to form nitric oxide in the first step of the production of nitric acid. Two principal gas-phase re

nevsk [136]

Answer:

4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O

2NO(g) + O₂(g) → 2 NO₂

Explanation:

First of all, we need to consider the reaction for production of ammonia. In this reaction we have as reactants, nitrogen and hydroge.

3H₂ (g) + N₂(g) → 2NH₃ (g)

Afterwards, ammonia reacts to oxygen, to produce NO and H₂O

The equation for the process will be:

4NH₃(g) + 5O₂(g) → 4NO(g) + 6H₂O

Then, we take the nitric oxide to make it react, to produce NO₂, in order to produce nitric acid, for the final reaction:

2NO(g) + O₂(g) → 2 NO₂

3NO₂(g) + H₂O(g) → 2 HNO₃ (g) + NO(g)

<h3>What is thyroid cancer?</h3>

Cancer that originates in the tissues of the thyroid gland is known as thyroid cancer. It is a condition where cells develop improperly and are susceptible to spreading to different bodily regions. A bump in the neck or swelling are examples of symptoms. Thyroid cancer is not always diagnosed because it can move from other parts of the body to the thyroid.

Young age radiation exposure, having an enlarged thyroid, and family history are risk factors. Papillary thyroid cancer, follicular thyroid cancer, medullary thyroid cancer, and anaplastic thyroid cancer are the four primary kinds. Ultrasound and tiny needle aspiration are frequently used in diagnosis. As of right now, it is not advised to screen those who are healthy and at normal risk for the disease.
