What makes an element and ion?

An ion is a charged atom or molecule. When an atom is attracted to another atom because it has an unequal number of electrons and protons, the atom is called an ION. If the atom has more electrons than protons, it is a negative ion, or ANION. If it has more protons than electrons,it is a positive ion.

What are ions of an element?

Ions are atoms or groups of atoms that have either lost or gained electrons so they have a positive or negative charge. Ions are different to isotopes and are not to be confused. Ions are atoms that have gained or lost electrons.

Do all elements have ions?

All elemental atoms contain the same number of protons and electrons, thus giving them a neutral charge. An ion is any element that contains a different number of protons and electrons resulting in either a positively or negatively charged atom. Refer to an element with either a positive or negative charge as an ion.

Are elements and atoms the same?

An atom is the part of an element. A particular element is composed of only one type of atom. Atoms are further composed of subatomic particles called electrons, protons and neutrons. Elements can combine with each other to form molecules via chemical reaction.

Is oxygen an ion?

Oxygen, O. Oxygen is in Group 6. It has six electrons in its outer shell. It gains two electrons from one or two other atoms in reactions, forming an oxide ion, O 2-.

What is the difference between molecules and elements?

Molecule is a substance with two or more atoms bonded together such as the oxygen humans breathe (O2). Elements are pure substances made up of all the same atoms such as gold (Au), hydrogen (H), and oxygen (O). Elements all have the same number of protons in their nuclei and can’t be broken down.

What is the difference between an element and compound?

Elements are substances that are pure in their nature and are composed of a single atom. Compounds are also pure substances that are composed of elements in definite proportions. Compounds can be broken down using chemical reactions. …

What is ionic in science?

ionic bond, also called electrovalent bond, type of linkage formed from the electrostatic attraction between oppositely charged ions in a chemical compound. The atom that loses the electrons becomes a positively charged ion (cation), while the one that gains them becomes a negatively charged ion (anion).
