only oxygen is a gas :)
At room temperature, oxygen is a gas.
Oxygen is an element and don'y contain any other element.
Oxygen has 8 neutrons. However, there are other isotopes that have a different number than this.
Almost every other element except the elements in group 18 bond with oxygen to form compounds.
Special chemical reactions such as hydrogen bonding.
Oxygen combined with one other element is an oxide.
Oxygen is not a mixture, it is a pure element. Air, however, is a mixture of many different elements. In other words, oxygen only has oxygen in it. Air has oxygen, nitrogen, carbon, hydrogen, and other elements in it.
Oxygen is made of atoms with 8 protons, 8 neutrons, and 8 electrons. It belongs to the group of nonmetal elements on the periodic table and is essential for respiration and combustion.
Oxygen differs from the other elements in the oxygen group (sulfur, selenium, tellurium, and polonium) in terms of its physical and chemical properties. Oxygen is a colorless and odorless gas at room temperature, while the other elements are solids. Additionally, oxygen is highly reactive and forms oxides readily, whereas the other elements have different chemical behaviors and may not readily form oxides.
Fluorine has similar chemical properties to chlorine. This is because both fluorine and chlorine belong to the same group on the periodic table (Group 17) and have similar electronic configurations, leading to comparable reactivity and chemical behavior. Oxygen, on the other hand, belongs to a different group (Group 16) and exhibits its own set of unique properties.
Oxygen is unique in its group because it is a diatomic gas in its elemental form, while other elements in its group are typically solid or liquid at room temperature. Additionally, oxygen readily forms compounds with almost all other elements, exhibiting a high electronegativity compared to others in its group.
Sand is a mixture of different elements (such as silicon, oxygen, and others) and is not considered an element on its own. Iron, on the other hand, is an element with the symbol Fe on the periodic table.
