what is constriction
Chromosomes can be classified into 4 types based on the...
The atom is more stable if it has a full outer shell. A sodium atom can lose its outer electron. It will still have 11 positive protons but only 10 negative electrons. So, the overall charge is +1.
The chloride ion /ˈklɔːraɪd/ is the anion (negatively charged ion) Cl−. It is formed when the element chlorine (a halogen) gains an electron or when a compound such as hydrogen chloride is dissolved in water or other polar solvents.
NaCl
The formula for table salt is NaCl. It is the result of Na+ ions and Cl- ions bonding together (Figure 4.3. 3). If sodium metal and chlorine gas mix under the right conditions, they will form salt.Sep 23, 2021
When a sodium atom transfers an electron to a chlorine atom, forming a sodium cation (Na+) and a chloride anion (Cl–), both ions have complete valence shells, and are energetically more stable. The reaction is extremely exothermic, producing a bright yellow light and a great deal of heat energy.
The breaking and making of chemical bonds can explain chemical reactions and energy flow. True. When Sodium and chlorine ions form an ionic bond, the heat that is release is called. heat of formation.
covalent bond
A covalent bond is a chemical bond that involves the sharing of electron pairs between atoms. These electron pairs are known as shared pairs or bonding pairs, and the stable balance of attractive and repulsive forces between atoms, when they share electrons, is known as covalent bonding.
Ionic compounds are also known as electrovalent compounds. The chemical bond formed by the transfer of electrons from one atom to another is known as Ionic bond.
ionic bonds form when electrons are transferred from one atom to another atom. ions of different elements can combine by forming ionic bonds . positive ions & negative ions form when atom s lose or gain electrons. … Atoms ,non-metal of elements tend to lose electrons when they form bonds.
covalent bond
The two chlorine atoms are said to be joined by a covalent bond. The reason that the two chlorine atoms stick together is that the shared pair of electrons is attracted to the nucleus of both chlorine atoms.Aug 21, 2020
What occurs when an atom of chlorine forms a chloride ion? (1) The chlorine atom gains an electron, and its radius becomes smaller. The chlorine atom gains an electron, and its radius becomes larger.
Explanation of what happens when sodium reacts with chlorine: … The sodium atom becomes a positive sodium ion. The chlorine atom becomes a negative chloride ion. Both sodium ions and chloride ions have full electron shells.
Sodium, Na
Sodium is also in Group 1. It has one electron in its outer shell. When this electron is lost, a sodium ion, Na +, is formed.
Consequently, they tend to lose electrons and form cations. Conversely, most nonmetallic atoms attract electrons more strongly than metallic atoms, and so gain electrons to form anions.

Cation vs anion chart.
Cation | Anion | |
---|---|---|
Examples | Sodium (Na+), Iron (Fe2+), Ammonium (NH4+) | Chloride (Cl–), Bromide (Br–), Sulfate (SO42–) |
Cations. A neutral sodium atom is likely to achieve an octet in its outermost shell by losing its one valence electron. The cation produced in this way, Na+, is called the sodium ion to distinguish it from the element. The outermost shell of the sodium ion is the second electron shell, which has eight electrons in it.
In the formation of a chloride ion from an isolated gaseous chlorine atom, 3.8 eV energy is released which would be equal to Ionisation potential of Cl−. The electron affinity or electron gain enthalpy of the chlorine atom is equal in magnitude and opposite in sign to the ionization potential of chloride ion.
15. The reason a bond is formed between chloride ions and sodium ions is because they have opposite charges. TRUE: the opposite charges attract them together, and this force of attraction is the ionic bond.
Ionic bonds
Ionic bonds usually occur between metal and nonmetal ions. For example, sodium (Na), a metal, and chloride (Cl), a nonmetal, form an ionic bond to make NaCl.
