Which is is more informative 17cl or cl35 why

Answer 1

Question:

Which is is more informative 17cl or cl35 why?

Answer:

What is Chlorine?

⇒ Chlorine is a element with an atomic number 17 , average atomic weight 35 and valency 1 and is represented by the symbol Cl .

⇒Electronic configuration-2,8,7

K-2 electrons

L-8 electrons

M-7 electrons

⇒ No. of electrons = 17

⇒ No. of protons = 17

⇒ No. of neutrons = 35 - 17 =18 ,37 - 17 =20 , 36 - 17 =19 ( since there are isotopes)

• Chlorine is the second lightest halogen and is represented as Cl.
• The atomic number of this chemical element is 17.

• It appears as a pale yellow-green gas.
• Liquid chlorine can cause skin burn and chlorine in its gaseous form irritates the mucous membrane.
• Its position as per the periodic table is between fluorine and bromine.
• There are two isotopes of chlorine that are stable.

Isotopes are the molecules of same element having different masses.

following are the informative things about them:

1. They have same chemical formulas.

2. They have same chemical properties.

3.They have different molecular masses.

4. They have different physical properties.

• They are ₁₇Cl³⁷ and ₁₇Cl₃₅. ₁₇Cl³⁶ is the stable radioisotope of chlorine. Sodium chloride is the most common compound of chlorine whereas the simplest is hydrogen chloride.

• Sodium chloride has a molecular formula NaCl whereas hydrogen chloride has a molecular formula HCl. It is highly reactive. Carl Wilhelm Scheele who was a Swedish chemist discovered Chlorine in the year 1774.

• Chlorine is the second halogen in the periodic table, being a nonmetal in group 17.

• Hence, its properties are similar to fluorine, bromine, and iodine, and are generally intermediate among those of the first two.

• Chlorine  seven electrons serving as its valence electrons in the third and outermost shell.

• As all halogens, it is thus one electron short of a full octet, and is thus a strong oxidizing agent, interacting with other elements to complete its outer shell.

• This element is intermediate in the electronegativity between fluorine and bromine (the electronegativity of fluorine is 3.98, the electronegativity of chlorine is : 3.16, the electronegativity of bromine is 2.96, and the electronegativity of iodine is 2.66).

• This element is less reactive than fluorine and more reactive than bromine, in line with periodic patterns.

• Even though it is a weaker oxidizing agent than fluorine, it is stronger than bromine.

• In comparison, the chloride ion is a weaker reduction agent than bromide, but one stronger than fluoride.

• The atomic number of chlorine is 17.

• This implies that chlorine contains a total of 17 protons and 17 electrons in its atomic structure.

• These electrons are arranged into 3 primary electron shells.

• The first electron shell belonging to chlorine contains a total of two electrons whereas the second electron shell of chlorine contains 8 electrons.

• Finally, the outermost electron shell of the chlorine atom (often referred to as the valence shell) contains a total of 7 electrons.

• Therefore, the valency of chlorine is often considered to be 7.

• However, it is important to note that chlorine needs only one more electron to complete its octet configuration.

• Therefore, the valency of chlorine can also be considered to be 1.

Cl Uses (Chlorine):

• It is used to get rid of the smell of putrefaction

• It is used as a disinfectant

• Chlorine is used in the treatment of drinking water to kill bacteria

• It is used to clean swimming pools

• It is used in the production of paper and paper products

• It is used as an antiseptic

• It is used to produce drugs

• It is used in the manufacture of dyes and plastics
