Brass as it is an alloy where as all the other three are basic elements. So brass will not be available in the Periodic Table. No atomic number for brass. But Mercury has 80, gold has 79 and Nitrogen has 7 as atomic number.
Carbon is the odd one out, because that's the only element in this row
Iron is an element. The other two are alloys containing copper.
oxygen because it is a gas while oil,alcohol and mercury is liquid.
sulfur
Among iron, gold, carbon, and silver, the odd member is carbon, the only non-metal of the group. On the periodic table, the three metals are all in the central "transitional metals" area, but carbon is on the right side among the non-metals.
Brass is the odd one out among aluminium, brass, copper, and iron. Brass is an alloy while the other three are elements.
iodine
Oxygen - as you can touch the other three Salt - as the other three are elements, and salt is a compound (NaCl)
Carbon is the odd one out, because that's the only element in this row
If a compound contains an even number of nitrogen atoms (or no nitrogen atoms), its molecular ion will appear at an even mass number. If, however, a compound contains an odd number of nitrogen atoms, then its molecular ion will appear at an odd mass value. This rule is very useful for determining the nitrogen content of an unknown compound.
why do you have mercury? it's odd but most tv screen companies would take it
Grass as it is the only one not made of metal.
Iron is an element. The other two are alloys containing copper.
what is the odd one lithium, nitrogen , oxygen , carbon
It is an idiom that means one of a number of listed things or concepts is different from the others in the list in some characteristic way.For example, in the list "one, two, three, right" the word "right" is the odd one out because it is not a number. In the group "gold, silver, copper, zinc, mercury" the odd one may be mercury because it is the only one of the five metals that is liquid at room temperature.
Because he had contact with Mercury which effects the brain and makes you go mad.
