The charge from the protons and electrons. If an atom loses an electron, it will have a net positive charge. If an atom gains an extra electron, it will have a net negative charge.
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
A polyatomic ion is a group of atoms that behaves like a single ion. This group of atoms carries a charge and acts as a single unit in chemical reactions.
Yes, the phosphate groups in DNA contribute to its overall negative charge. Each phosphate group contains a negatively charged oxygen atom, which imparts a negative charge to the DNA molecule. This negative charge plays a crucial role in the stability and structure of DNA, as well as in interactions with proteins and other molecules.
The size of atoms is primarily determined by the arrangement of electrons in the electron cloud surrounding the nucleus. The number of electron shells and the effective nuclear charge also play a role in determining the size of atoms. Additionally, the atomic radius of atoms generally increases as one moves down a group and decreases across a period on the periodic table.
An ion is a particle that carries a charge, either positive or negative, due to losing or gaining electrons. It can be a single atom or a group of atoms that have an overall charge. A molecule is a group of atoms held together by chemical bonds and may or may not carry a charge.
Ions are formed when atoms have charges. Cations are species with positive charge. Anions are species with negative charge.
That's called an ion.
Zero. (Ions have charge; atoms are always neutral.)
Such charged particles are known as ions. A positively charged ion is called a cation; a negatively charged particle is called an anion.Ions: cation (positive charge) and anion (negative charge)
they are the cations
A polyatomic ion is a group of atoms with a charge.

An ion is an atom (or group of atoms) with an electrical charge.
An atom or group of atoms with a negative charge is called an anion. Anions have gained one or more electrons, leading to an overall negative charge.
Atoms with charge are called ions. These ions have either gained or lost valence electrons to gain a net positive or net negative charge. Ions with a positive electrical charge of positive 1 (+1) are metals in the Alkali Metals Group and Hydrogen. Ions with a negative electrical charge of 1 (-1) are elements in the Halogen Group.
a tightly bound group of atoms that behaves as a unit and has a positive or negative charge
No. What you describe is called a molecule. An ion is an atom or group of atoms with a net electrical charge.
