Hydrogen.
Neither, Sodium is an Alkali Metal.
rutherfordium is a transition element
It is located, in the periodic table, with the metalloids. However, it is a transition metal.
No, sodium is not a noble gas. It is a reactive metal that belongs to the alkali metal group in the periodic table. Noble gases are a group of non-reactive elements that include helium, neon, argon, krypton, xenon, and radon.
No, cesium is not a gas. It is a solid metal element in the alkali metal group of the periodic table. Cesium is soft, silvery-gold in color, and has a low melting point.
Nitrogen is a gas, not a metal.
helium is a noble gas. lithium is an alkali metal.
It is a metal (alkali metal)
Nitrogen is a gas, not a metal.
When an alkali metal reacts with water, it produces an alkali metal hydroxide and hydrogen gas. This is a highly exothermic reaction, with the alkali metal displacing hydrogen from the water molecule.
No, neon is a noble gas.
No, it isn't. One of the clues of telling that is isn't, is that hydrogen is a gas, and If it was an alkali METAL, it would not be a gas, but a metal. Its place on the table does make sense, though; hydrogen tends to behave like other members of it's column in chemical reactions. For example, All of the alkali metals, and hydrogen Combine with oxygen to form the compound X2O, where "X" is either Hydrogen, Lithium, Sodium, Potasium, Rubidium, Cesium, or Francium.
