name 2 elements?

Question

its science homework
so i suppose iron would be solid
carbon dioxide is gas
i think this is correct

Answer 1

Carbon Dioxide is not an element, it is a compound.
For solids, you can pick any metal, except mercury. Iron, copper, lead, calcium, uranium.
For liquids, your choices are bromine or mercury.
For gases, you have hydrogen, oxygen, nitrogen or any of the noble gases (the right-hand column, or period, on the Periodic Table). These include helium, argon, neon, radon, etc.
The ancient elements, fire, water, air and earth, are not elements at all.
Fire is a chemical reaction called oxidation. Earth is amixture of organic and inorganic solids. Water is a compound and air is a mixture of compounds and molecular elements (like nitrogen, oxygen, argon and hydrogen).

Answer 2

Any of the 103 elements listed in the Periodic Table.
Elements are pure substances e.g. Hydrogen Gas and Iron solid.
Carbon dioxide is a compound of 2 elements - Carbon (solid) and Oxygen (gas).

Answer 3

Here you go buddy, you have 103 elements to choose from here in the periodic table of elements, just click on the ones you're interested in:

(BTW- Carbon dioxide is a compound that is made up of two elements- one Carbon, and 2 Oxygen molecules [CO2]).

Ignore the morons talking about fire, water, earth, air & metal as these were ancient 'elements' and they are proven to be wrong now. I'm suprised at how stupid some people are; iron IS an element- atomic number 26 [the atomic number is the number of protons found in the nucleus of the atom].

Two examples of elements at the different physical states at room temperature:
Gas- Hydrogen & Oxygen (H & O)
Liquid- Mercury & Bromine (Hg & Br)
Solid- Carbon & Iron (C & Fe)

To the idiots who answered with retarded answers- If you're a moron and don't know what you're talking about then don't f'ing answer questions on chemistry with crap.

Answer 4

iron is a solid at room temperature and carbon dioxide is not an element but a molecule. A element that is a gas would be something like hydrogen.

Answer 5

Iron (Fe) is an element and a solid.
Carbon Dioxide(CO2) is a compound, NOT an element, but it is a gas.
However, Carbon(C) is an element, and a solid. Oxygen(O) is also an element and a gas.

Answer 6

There are 100+ elements in the periodic table..some solid,some liquid and some gas.
Carbon is an element ,so is oxygen but carbon dioxide is NOT.
Neither is water..it's a compound of hydrogen and oxygen (H2O.)
The first two elements..Hydrogen(H) and Helium (He)

Answer 7

Hello,

(ANS) Elements are substances that have unique atomic structures & are often the building blocks for the creation of substances.

The following are elements:-

Hydrogen
Oxygen
Nitrogen
Carbon
Uranium
Plutonium
Gold

Elements can take different forms, gases, solids, liquids. If you want to know more see a copy of the periodic table, this shows ALL the known discovered elements.

IR

Answer 8

iron is an element. carbon dioxide isnt it does not appear on the elemental table as they are compounds.
Try Zinc as a solid and Oxygen or Hydrogen as a gas.

Answer 9

well iron is a metal so yes it would be a solid and carbon dioxide isn't an element it compound its a combination of carbon and oxygen but yes it is a gas

Answer 10

Hydrogen and Helium are the simplest elements. You can look at a list of all the elements by putting 'periodic table' in the search box.There's even one named after Albert Einstein-it's called Einsteinium
