gain
If the chemical bond is ionic, an electron is gained or lost. If it is covalent, the electron is shared equally; if it is polar covalent, the electron is shared unequally. If the bond is intermolecular, no parts of the atom are actually shared, gained, or lost; the atom itself is simply attracted to other atoms.
When heat is added to an atom, its electrons gain energy and move to higher energy levels, causing the atom to become excited. When electrical energy is added, it can either cause the atom to gain or lose electrons, leading to the formation of ions. Both processes can result in changes to the atom's chemical properties.
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
Atoms do not always lose electrons. Electrons can be gained too. Atoms always try to have their outer most shell filled, and some atoms such as ones of potassium can easily lose an electron rather than gain an electron. So it would lose an electron to a different atom so that it would have a full outer shell and the other atom would also have a full outer shell.
The ion given is formed when the neutral arsenic atom gains three electrons.
The only way a carbon atom becomes stable is if they gain or lose electrons. Typically carbon will bond with other elements to do this.
The gain and/or lose of electrons.
It needs to lose, or gain, electrons.
A full outer electron shell. Atoms tend to be more stable when they have a full valence shell, which typically contains eight electrons. This stability makes it less likely for the atom to either lose or gain electrons.
No. A metallic atom will typically lose electrons.
Lithium loses electrons.
Carbon's symbol is C. A carbon atom has no charge, but a carbon ion has a +2 charge.
A Fluorine atom has an atomic number of 9. Draw out the electron shell diagram for Fluorine. Is a Fluorine atom more likely to gain, lose or share electrons to fill its valence shell?
Charged particles that form when atoms gain or lose electrons are called ions. When an atom gains electrons, it becomes a negatively charged ion (anion). When an atom loses electrons, it becomes a positively charged ion (cation).
A chlorine atom would gain one electron to become an ion because it tends to achieve a stable electron configuration by having a full outer shell of electrons.
Electrons in the outer most shell are called Valence Electrons.
The most stable electron configuration for any atom is to have a complete outer shell. For the smallest atoms, that can be no electrons at all (for H+) since no shell is equivalent to a complete shell, or just two electrons in the outer shell, such as for a helium atom, but for most elements that means 8 electrons in the outer shell. We then have atoms which have five or more electrons in their outer shell and therefore need three or less to complete their shell, and they tend to gain electrons because it is easier to gain three than it is to lose five. Similarly, there are atoms with three or fewer electrons in their outer shell, and they tend to lose electrons because it is easier to lose three than it is to gain five. In the middle we have an atom such as carbon, with four electrons it its outer shell; it can gain or lose electrons with equal ease.
