Neon and argon are two other gases that are denser than helium and do not
react easily with other elements.
Group 1 elements, such as lithium, sodium, and potassium, easily give up electrons because they have one electron in their outer shell and are highly reactive. Additionally, elements in Group 17, such as fluorine and chlorine, can also easily gain electrons.
A free element refers to an element that exists in nature in its pure form without being combined with other elements. These elements are often found in the Earth's crust and can be easily isolated without the need for chemical reactions. Examples of free elements include gold, silver, and oxygen.
Sulfur is a yellow, solid element at room temperature and pressure. It is also brittle and easily crumbles into a powder when touched.
You can identify elements in a compound by looking at the chemical formula and noting the symbols of the elements present. Each element is represented by a unique symbol (e.g. H for hydrogen, O for oxygen). You can determine the number of atoms of each element by the subscripts next to the element symbol in the formula.
The atomic number is equal to the number of protons in an atom's nucleus. To determine the atomic number of an element, you simply count the number of protons in the nucleus of an atom of that element. This number is unique for each element and is listed on the periodic table of elements.
Yes, americium is a reactive element.
Measure of its chemical reactivity.
Sulfur is a stable element under normal conditions, but it can react with other elements to form compounds. In its elemental form, sulfur exists as a solid at room temperature and does not decompose easily.
By having a close look on the electronic configuration we can easily tell that which element will combine with the other elements and by which force too.
Yes, each element has specific physical properties.
Yes. the reaction is exothermic and quite violent.
The most volatile element besides hydrocarbons is likely hydrogen. Hydrogen is a gas at room temperature and pressure and has a low boiling point, making it highly volatile and easily evaporating into the atmosphere.
The metals, except for mercury, which is liquid at room temperature.

Sulfur is a yellow, solid element at room temperature and pressure. It is also brittle and easily crumbles into a powder when touched.
This property can be useful in containing substances, like if you want to contain liquid nitrogen you would use an iron container (or practically any other element because nitrogen is almost inert) because the two elements don't interact with each other.
