At room temperature oxygen is a gas, mercury, ethanol and oils are liquids.
.
Oxygen
Iron. Iron is a metal while the others are nonmetals
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.
None of the metals are gasses at room temperature.
No, O3 does not have an odd number of valence electrons, it has 12e- Explanation: Oxygen by itself has a total of 6 valence electrons, and since ozone (O3) is made of three Oxygen's it will be 6e- X 3 which yields 18e- . But since these three elements are (covalent) bonded together with a single and double bond you need to subtract 2e- and 4e- which will give us the final answer of 12e- You can now conclude that it has an even number of valence electrons.
Because it is a gas. A gas is not a metal - thus non metal.
Oxygen - as you can touch the other three Salt - as the other three are elements, and salt is a compound (NaCl)
iodine
why do you have mercury? it's odd but most tv screen companies would take it
what is the odd one lithium, nitrogen , oxygen , carbon
Because he had contact with Mercury which effects the brain and makes you go mad.
why do you have Mercury? it's odd but most tv screen companies would take it
bronze ****************************** Mercury, as it is the only metal that is a liquid at room temperature.
They all do.
Very Odd but service manual states it is 123456
carbon dioxide
This element is iodine because it is a halogen.
No because its alcohol and its doing harm to your body if you drink to much, but an odd glass wont harm :)
