Not quite sure what you mean by how many gases. Bromine is a gas all by itself. It is liquid at room temperature, but it is still considered a gas. It's own element. So there is only one gas in Bromine.
the noble gases, krypton, xenon and radon are larger than bromine
No, not all halogens are gases. Fluorine and chlorine are gases at room temperature, while bromine is a liquid and iodine is a solid.
No, not all halogens are gases at room temperature. Fluorine and chlorine are gases at room temperature, bromine is a liquid, and iodine is a solid.
At standard temperature and pressure (STP), fluorine (F2), chlorine (Cl2), and bromine (Br2) are gases. Iodine (I2) is a solid at STP.
You can see some halogen gases, such as Chlorine and Bromine and Iodine because they are coloured. Most other gases are colourless and cannot be seen.
No, air is not denser than bromine. Bromine is a dense, dark red liquid at room temperature, while air is a mixture of gases, with a lower overall density.
The maximum is 8 for noble gases.
At room temperature and pressure, fluorine and chlorine are gases, bromine is liquid and iodine is a solid
Fluorine (F2), chlorine (Cl2), bromine (Br2), and iodine (I2) are halogens that exist as gases at room temperature and pressure. At standard conditions, fluorine and chlorine are diatomic gases, while bromine is a diatomic liquid and iodine is a solid.
Zinc and mercury are solids at room temperature, whereas oxygen and bromine are gases.
At room temperature, fluorine and chlorine are gases, bromine is a liquid, and iodine and astatine are solids.
No, bromine, mercury, chlorine, sodium, and sulfur are not gases. Bromine is a liquid, mercury is a liquid at room temperature, chlorine is a gas, and sodium and sulfur are solid at room temperature. Each of these elements can undergo chemical reactions under the right conditions.
