What happens to the valence electrons when an ionic bond forms between sodium and chlorine?
When an ionic bond forms between sodium and chlorine, the valence electron from the sodium atom is transferred to the chlorine atom. This transfer results in the formation of positively charged sodium ions and negatively charged chloride ions, which are then attracted to each other to create the ionic bond.
What charge does as electron have?
An electron has a negative charge of -1.6 x 10^-19 coulombs.
What are two ways in which the valence electrons of atoms participate in bond formation?
Valence electrons can be shared between atoms in covalent bonds, where they form overlapping electron clouds. Alternatively, valence electrons can be transferred from one atom to another in ionic bonds, resulting in the formation of positively and negatively charged ions that are attracted to each other.
What is the net charge of the ionic compound calcuim flouride?
The electronic configuration of F is [He] 2s2 2p5. An F atom needs just one more electron in its 2p shell to form the stable noble gas configuration. In gaining a single electron an F atom incurs a -1 negative charge. Thus, the charge on F ion is -1. The chemical formula for the F ion is F-.one negative
Purely ionic bonds do not occur because the atoms that gives up an electron in such a bond?
Purely ionic bonds do not occur because the atoms that give up an electron in such a bond would be left with a positive charge, and those that accept an electron would have a negative charge. This would create an imbalance in charge, leading to the formation of an ionic compound where the atoms are held together by electrostatic attraction.
How do you use electron configurations to predict formulas of ionic compounds?
They show how many bonds an atom can create, and whether it gains or loses electrons. (Atoms with 5-7 valence electrons tend to gain electrons, atoms with 1-3 valence electrons tend to lose electrons, atoms with 4 valence electrons can do either, and atoms with 8 valence electrons don't naturally bond)
What happens to the valence electrons when an ionic bond forms between sodium and chlorine?

This transfer results in the formation of positively charged sodium ions and negatively charged chloride ions, which are then attracted to each other to create the ionic bond.
What is an ion and what happens to electrons when ions are formed?
An ion is an atom with a net electric charge. An ion is formed when an atom either gains or loses a valence electron. Atoms with an unfilled outer shell tend to gain or lose electrons so they can achieve a filled outer shell. Atoms that gain an electron are negative ions, and atoms that lose an electron are positive ions.
How can a magnesium atom bond with oxygen atom?
The magnesium has 2 valence electron while the oxygen misses 2 electron to complete its octet. An atom is always more stable when it has 8 valence electrons. The magnesium will create an ionic bond with the oxygen by giving its 2 electrons to form Magnesium Oxide, MgO.
What charge does as electron have?
An electron has a negative charge of -1.6 x 10^-19 coulombs.
How many atoms of Lithium and Fluorine are needed to create the total charge of zero?
To create a total charge of zero, lithium with an atomic number of 3 (Li) needs to lose one electron to form Li+ with a charge of +1. Fluorine with an atomic number of 9 (F) needs to gain one electron to form F- with a charge of -1. Therefore, one atom of lithium and one atom of fluorine are needed to create a compound with a total charge of zero.
What would be the electrical charge of fluorine atom that gained an electron?
The fluorine atom, which normally has 9 protons and 9 electrons, will have a charge of -1 after gaining an electron. This is because it now has 10 negatively charged electrons and only 9 positively charged protons.
What if you add one electron to the element having 9 protons and 10 neutrons?
By adding one electron to an element with 9 protons and 10 neutrons, you would create a negatively charged ion. The electron would occupy an orbital in the electron cloud, resulting in the element being one electron short of achieving a stable electron configuration. This ion would have a charge of -1 due to the extra electron.

Is the valence electron farthest or closest to the nucleus?
No. By definition, valence electrons are the furthest electrons from the nucleus in the atom. They are the electrons most easily removed from (or added to) the atom to create ions. A loophole to this answer might be to say that hydrogen and helium only have 1 and 2 electrons respectively so their valence electrons are close. That's a matter of perspective, as no electrons are really "close" to the nucleus to begin with. A typical comparison is to imagine a grape seed in the middle of a football stadium. The grape seed represents the nucleus, and an electron would be a speck of dust on the outside of the stadium.

What is an example of How ions form?
Ions are formed when elements either gain or lose their electrons. For example, Sodium (Na), since it has one electron in its outer shell (valence electron) it will be easier for the atom to lose its one valence electron and give it to an element that would want to gain that one electron, for example, Chlorine. This reaction of gaining or losing electrons would create an either negative ion (gained electrons) or a positive ion (lost electrons). For the example that I did, the element Sodium would lose its one electron in its outer shell making it Na +1 because it would have one more positive charge then it would negative charge.
