No, an ion can be made up of one or more atoms; and is classed as an ion when there is a difference in the total number protons in the nucleus/nuclei of the atom/compound and the total number of electrons orbiting the atom ( /atoms if it's a compound.)
An atom with more protons than electrons is a cation.
Ion
A negative ion has gained one or more electrons to become negatively charged, while its parent atom is neutral with an equal number of protons and electrons. This means the negative ion has more electrons than its parent atom.
If an atom has lost more protons than electrons, it becomes a positively charged ion. This is because it now has more positive charge (from the protons) than negative charge (from the electrons), leading to an overall positive charge.
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
monatomic Ion- contains one atom polyatomic ion- contains more than one atom
An atom with more protons than electrons is a cation.
an ion with a 2- charge has 2 more electrons than usual
An atom becomes an ion by gaining or losing electrons. When an atom loses electrons, it becomes a positively charged ion (cation) as it has more protons than electrons. On the other hand, when an atom gains electrons, it becomes a negatively charged ion (anion) as it has more electrons than protons.
i think it contains hydrogen
it is a positive ion
Ion
it contains 1 more proton that electron.
A negative ion has gained one or more electrons to become negatively charged, while its parent atom is neutral with an equal number of protons and electrons. This means the negative ion has more electrons than its parent atom.
If an atom has lost more protons than electrons, it becomes a positively charged ion. This is because it now has more positive charge (from the protons) than negative charge (from the electrons), leading to an overall positive charge.
a calcium atom is larger because it contains more electrons than a calcium ion. When a calcium atom loses electrons to become a calcium ion, it becomes smaller due to the loss of electron-electron repulsion, causing the remaining electrons to be pulled closer to the nucleus, resulting in a smaller size.
Losing electrons makes an atom positively charged (cation) by having more protons than electrons, while gaining electrons makes an atom negatively charged (anion) by having more electrons than protons.
