Cl, it is the only one which is a non-metal gas
Chlorine
It's the only non-metal and it's the only gas at STP (standard temperature and pressure)
Cs
Chlorine is a gas, the other three are solids
chlorine is a gas the other three are not
The diatomic molecules in the periodic table are also known as the Fab 7. They are in a row such that they create kind of an upside down L (excluding Hydrogen at the top left): Nitrogen, Oxygen, Fluorine, Chlorine, Bromine, Iodine, and lastly, Hydrogen.
oxygen because it is a gas while oil,alcohol and mercury is liquid.
Iron. Iron is a metal while the others are nonmetals
It depends on the compound its in. (the range for its oxidation number ranges from -1 to +7 [odd numbers in between are its oxidation numbers exp: -1, +1, +3, +5, +7]) For example if its cl- (only a chlorine ion) then its oxidation number is -1 (simmilar to its valency). If its in the compound NaCl, We know that its total oxidation is 0. (all compunds have an oxidation number of zero) Na has an oxidation number +1. Therefore +1 + x = 0 -> through this you can find the oxidation number of chlorine in this compund. (x representing the oxidation number of chlorine). In this case the answer is x=-1. In the compound HClO4 (perchloric acid), the oxidation number of the total compund is equal to 0. Oxygen has an oxidation number of -2, and hydrogen has an oxidation number of +1. Therefore, (+1) + x + (-2*4) = 0 (oxygen in this compund has 4 atoms so -2 multiplied by 4) Thus: +1 + x + (-8) = 0 +1 + x = 8 x= 8 -1 x= +7 So we can see here that the oxidation number of chlorine has become +7. Do the same for any compound that chlorine is involed in. Hope it helps.
No
This element is iodine because it is a halogen.

what is the odd one lithium, nitrogen , oxygen , carbon
chlorine and oxygen both have different electro negativities due to which polarity develops between the bond and one odd electron present in chlorine make different type of Dpie - Ppie bond with it
oxygen because it is a gas while oil,alcohol and mercury is liquid.
carbon dioxide
Oxygen - as you can touch the other three Salt - as the other three are elements, and salt is a compound (NaCl)
Nitric oxide (NO) is an example of a molecule with an odd electron. It has one unpaired electron in its molecular orbital diagram, making it a radical.
No Yes. It is possible although it would require considerable energy and pressure. NO: Hydrochloric acid could NOT be converted into perchlorate acid H2ClO4. HClO4, HClO3 (1.46 V), Cl2 (1.36 V) and even HClO (1.63 V) are stronger oxidants (higher electro-potential) than Oxygen in acid environment (1.23 V), so they cannot be formed by oxygen as oxidant.
Iron. Iron is a metal while the others are nonmetals
Yes. Two Hyrdrogen molecules, one Oxygen molecule. The Hydrogen molecules are each bound to Oxygen at an odd angle making the molecule polar
