Carbon achieves a noble gas configuration by forming covalent bonds with other atoms, typically by sharing electrons to complete its valence shell. In forming compounds like methane (CH₄), carbon shares its four outer electrons with four hydrogen atoms, resulting in a full outer shell of eight electrons. This configuration mimics that of noble gases, which are stable due to having full valence shells.
No, for two reasons:It is no gas at STP, but fluid (melting point is −7.2 °C and boiling point 58.8 °C)It certainly is NOT noble, on the contrary: very aggressive (Bromine is a powerful oxidizing agent. It reacts vigorously with metals, especially in the presence of water, as well as most organic compounds, especially upon illumination.)
helium has the least density, xenon has the highest.
Condensation temperature at normal pressure would be −245.95°C.
Helium is a noble gas at room temperature, and exists as a colorless, odorless gas. Helium becomes a liquid at very low temperatures, about -269 degrees Celsius, and a solid at an even lower temperature of around -272 degrees Celsius.
The electron configuration of carbon in noble gas notation is [He] 2s^2 2p^2. This notation indicates that carbon has the same electron configuration as helium up to the 1s orbital, followed by the electron configuration of the remaining orbitals (2s^2 2p^2).
No, Na is sodium, an alkali metal. The noble gasses are in the far right column of the periodic table.
[He] 2s2 2p2
Xenon is a noble gas and it exists as a gas at room temperature (25 degrees Celsius).
At STP, all noble gases are gases. However, helium can be converted to liquid below-268.93 °C.
Argon is a gas at room temperature. It is in the noble gases on the Periodic Table.
