What do we call different forms of the same element?

What do we call different forms of the same element?

Allotropes are different structural forms of the same element and can exhibit quite different physical properties and chemical behaviours. The change between allotropic forms is triggered by the same forces that affect other structures, i.e., pressure, light, and temperature.

Can be different for the same element?

The atoms of a chemical element can exist in different types. These are called isotopes. They have the same number of protons (and electrons), but different numbers of neutrons. Different isotopes of the same element have different masses.

What are the forms of elements?

Even though elements are all made from the same type of atoms, they can still come in different forms. Depending on their temperature they can be solid, liquid, or gas. They can also take different forms depending on how tightly the atoms are packed together. Scientists call these allotropes.

Are different forms of the same element with different number of neutrons?

Atoms of the same element that differ in their numbers of neutrons are called isotopes. Many isotopes occur naturally.

What are two atoms of the same element?

Atoms of the same element (i.e., atoms with the same number of protons) with different numbers of neutrons are called isotopes. Most naturally occurring elements exist as isotopes. For example, most hydrogen atoms have a single proton in their nucleus.

What do all atoms of one element have in common?

They come in different kinds, called elements, but each atom shares certain characteristics in common. All atoms have a dense central core called the atomic nucleus. All atoms have at least one proton in their core, and the number of protons determines which kind of element an atom is.

How many atoms make an element?

2.8. Elements can be made of one atom, like He, or be elemental molecules, such as hydrogen (H2), oxygen (O2), chlorine (Cl2), ozone (O3), and sulfur (S8). Atoms are not drawn to scale. Some elements are monatomic, meaning they are made of a single (mon-) atom (-atomic) in their molecular form.

What causes an atom to be neutral?

When an atom has an equal number of electrons and protons, it has an equal number of negative electric charges (the electrons) and positive electric charges (the protons). The total electric charge of the atom is therefore zero and the atom is said to be neutral.
