In ionic compounds, atoms gain or lose electrons to form ions. ... When the atoms of each element first come together, both are electrically neutral. When they get close enough, an electron transfers from the sodium to the chlorine. This makes a positive sodium ion, Na+, and a negative chloride ion, Cl-.
Does chlorine and sodium form an ionic bond?
As a result of reaction between metal and non-metal, they are bonded with electrostatic force of attraction with each other; such bonds are called chemical bonds. Sodium is a metal whereas chlorine is a non-metal. Sodium metal reacts with chlorine to form an ionic compound, sodium chloride.
When an atom of sodium donates its sole valence electron to an atom of chlorine, the resulting positive and negative charges pull both ions tightly together , forming an ionic bond (Figure 2.4c). The resulting compound is sodium chloride, written NaCl.
Why does sodium and chloride form a bond quizlet?
Because of their positive or negative charge , these atoms are ions. The attraction of the positive ion to the negative ion constitutes the ionic bond. Sodium (Na) and chlorine (Cl) form ions (Na + and Cl-), which attract one another to form the ionic bond in a sodium chloride (NaCl) molecule.
What is the bond for sodium and chlorine?
Sodium will lose an electron to become Na + whilst chloride will gain an electron to form Cl – . These charged atoms are called ions. The strong forces or attraction between the two oppositely charged ions will hold them close together, forming the ionic bond .
Because the sodium ion has a positive charge, and the chlorine ion has a negative charge, they are attracted to each other , and form an ionic bond.
What ionic compound would you expect to form from the reaction of sodium and chlorine?
On an atomic level when a reaction takes place between two elements such as sodium and chlorine result in two oppositely charged ions is they combine to form an ionic compound, sodium loses its one electron to chlorine so chlorine gains one electron. It forms a chloride ion and forms the ionic compound sodium chloride .
What is the formula for sodium and chlorine bonding?
Table salt is made from a combination of atoms of sodium (Na) and chlorine (Cl) in a ratio of 1:1 forming the compound NaCl .
How many valence electrons does sodium have when forming an ionic bond with chlorine?
Sodium has one valence electron , and chlorine has seven. The one sodium electron can be donated to chlorine, and chlorine holds onto the two electrons that are in the Na−Cl ionic bond.
What is the ground state configuration for chlorine?
The neutral atom chlorine (Z=17), for instance has 17 electrons. Therefore, its ground state electronic configuration can be written as 1s 2 2s 2 2p 6 3s 2 3p 5 . The chloride ion (Cl – ), on the other hand, has an additional electron for a total of 18 electrons.
Which is the best explanation for why NaCl is an ionic compound?
Sodium chloride exhibits ionic bonding . The sodium atom has a single electron in its outermost shell,... An ionic bond is actually the extreme case of a polar covalent bond, the latter resulting from unequal sharing of electrons rather than complete electron transfer.
How do ionic bonds form?
2 Ionic Bonds. An ionic bond is formed by the complete transfer of some electrons from one atom to another . The atom losing one or more electrons becomes a cation—a positively charged ion. The atom gaining one or more electron becomes an anion—a negatively charged ion.
Is Sodium Bromide a covalent or ionic bond?
Is sodium bromide a covalent or ionic? Sodium bromide is an ionically bonded compound . The electronegativity of bromine is high enough and that the electromagnetic force between the Br and the Na atoms is great enough that an electron is transferred from the Na atom to the Br atom.
What happens when you mix sodium and chlorine?
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.
What kinds of bonds are formed between water and sodium?
When salt is mixed with water, the salt dissolves because the covalent bonds of water are stronger than the ionic bonds in the salt molecules.
Does the bond of sodium chloride break?
The NaCl crystals dissolve in water in a two step process. The Na-Cl ionic bonds are broken and the Na+ and Cl- ions are then solvated. Some energy is needed to breakthe ionic bonds and some energy is released when the ions are solvated.
