Answer:
a) Cl, 17 protons and 17 electrons
Explanation:
The elements of group 17 are called halogens. These are six elements Fluorine, Chlorine, Bromine, Iodine, Astatine. The atomic number of chlorine is 17. Its means it has 17 protons and 17 electrons.
The sum of neutrons and protons is the mass number of an atom while the number of protons are number of electrons is the atomic number of an atom. Thus the atomic mass of chlorine will be 17+18 = 35 amu
Number protons = 17
Number of electrons = 17
Number of neutrons = 18
Properties of Chlorine:
1. it is greenish-yellow irritating gas.
2. its melting point is 172.2 K
3. its boiling point is 238.6 K
4. it is disinfectant and can kill the bacteria.
5. it is also used in manufacturing of paper, paints and textile industries.
The answer is group 1A.
In the ionic compound formula X₂SO₄, SO₄ has a -2 charge. Hence to balance this -2 charge of SO₄, X must have a +1 charge.
Group 1A elements form X⁺ type of ions because they are metals. So, they have the tendency to lose electrons.
Hence, X must belong to the 1A group.
Ionic Compounds-
- Ionic compounds are formed by the electrostatic attraction between the anions and the cations.
- Cations are positively charged ions that are formed due to the loss of electrons.
- And the anions are negatively charged ions that are formed due to the gain of electrons.
- Due to this, they have opposite charges and form bonds known as Ionic Bond.
