Why doesn't chlorine make an ionic compound with bromine?
because both these elements are in the same group (7) of the periodic table and so each have 7 electrons in their outer electron shells.An ionic compound is formed when one atom which preferentially looses electrons from its outer shell bonds through electrostatic attraction to another atom which preferentially gains electrons.Some atoms will loose electrons in these sorts of chemical reactions because they have only a few electrons in their outer shell and it is energetically easiest for them to donate them in a reaction leaving the atom with a full outer shell, for example sodium has only one and looses it easily in reactions forming a positive sodium ion. Some atoms will accept extra electrons to form a complete outer shell, chlorine for example will accept one to become a negative chlorine ion. These two equal but oppositely charged ions will strongly attract each other.Elements with 7 electrons each could only chemically bond by sharing an electron pair, the 7th from each atom combining to make a pair that both could share. This is called covalent bonding. This is what happens when chlorine and the other halogen elements form molecules, they go round in pairs Cl2, Br2, I2 etc bonded through the shared electron pair. A more interesting question is, why doesn't chlorine form a covalent compound with bromine?
Why is sodium fluoride an ionic bond?
Ionic bonds exist between two atoms (or groups of atoms) based on their opposite electrical charge. In this case, sodium (Na) is positively charged +1 and fluorine becomes a fluoride ion (negatively charged at -1).The reason the electrons are held this way (as opposed to being shared as in a covalent bond) is due to the relative electronegativitiesof the two elements. Electonegativity is a measurement of how strongly an element 'wants' more electrons (in order to complete its valence shell).Sodium, way over on the left side of the periodic table, has a very low electronegativity:it is easier for it to lose one electron to become a cation (+ ion) and noble gas like. Fluorine on the other hand, is the electronegativitychampion - one extra electron brings it to a full stable 8 electron valence shell (octet).Put together a willing donor and a willing recipient and you have the recipe for an ionic bond. One quick way to tell ionic bonds is to look for metals bonded to electronegative anions - Cl, Br, Fl, O, etc.
When chlorine forms an ionic compound it gains one electron what symbol is used to represent the chloride ion formed in this way?
Cl- This is the symbol of a chlorine ion that gains one electron
Can chlorine bleach fumes explode?
Answer#1No. Chlorine (though deadly) is non-flammable. Pure chlorine can, however react explosively with certain metals. Much the same way metallic sodium reacts with water. BOOM!
What would a chlorine atom tend to do in bonding with another atom to form an ionic compound and why?
The most common bounds chlorine accepts are with Alcaline metals. They have only one valence electron, which chlorine would gladly steal so that his last orbital becomes full of electrons. This way both become stable, and they would form a very strong ionic compound.
Is it true NaCl is an atom of sodium and an atom of chlorine that have combined by sodium capturing one electron from chlorine?
No. It's the other way around where sodium loses an electron and chorine obtains one. However, you're right that it's an ionic bond, not a covalent bond.
How do you determine bond types?
The bond type is determined by the way they share electrons each other. For instance, hydrogen and chlorine share one electron each to form a molecule of HCl with a covalent bond. When sodium reacts with chlorine, the latter gains electrons to make a lattice by ions through ionic bonds.
What happens to the electrons in a formation of an ionic bond?
Example. Sodium, Na, donates an electron to chlorine, Cl because chlorine's electronegativity is much greater than sodium. So, both achieve the octet state this way and as opposite charges attract they are ionically bonded. Na + A cation and Cl - An anion Form. NaCl Sodium chloride.
What is the difference between the way carbon forms the crystal called diamond and sodium and chlorine form solid sodium chloride?
In sodium chloride the bond between chlorine and sodium is ionic; sodium chloride form large lattices. The crystalline structure is face-centered cubic.Diamond has also a similar (not identical) crystalline structure face-centered cubic. But the bonds between carbon atoms are covalent !
Is sodium chloride a covalent compound?
Sodium Chloride is not a covalent compound. Sodium and Chlorine do not form any covalent compounds exclusively with each other. Sodium Chloride is an ionic compound. I'm not going to go into too much detail, but generally speaking, any compound between a metal and a non-metal will be ionic. This is because most metals have a tendency to lose electrons in order to form stable positive ions and non-metals have an affinity to gain electrons in order to form stable negative ions. Once these ions have formed due to the transfer of electrons from the metal to the non-metal, the ions are left attracted to one another because of their differing charges. That electrostatic attraction is the basis of the ionic bond, whereas covalent bonds are characterized by two or more atoms sharing the same shell of electrons simultaneously. Covalent bonds are normally only seen in compounds between non-metals.The another angle we can predict the nature of bonding that is ELECTRINEGATIVITY DIFFERENCE. Now we see the reaction of NaCl . The elcrongativiy value of Na according to PAULI'S TABLE ,IS .93 and the Cl E.N value is 3.16 .So , 3.16 - .93 =2.23 . In this way the nature of NaCl is pure IONIC COMPOUND.
Is mercury covalent or ionic bond?
Mercury ions are cations. Chloride ions are anions. "In an ionic bond, the atoms are bound together by the attraction between oppositely-charged ions. In a covalent bond, the atoms are bound by shared electrons." 1 mercury ion loses 2 electrons to 2 chloride ions (i.e. 1 electron to 1 chloride ion), thus forming an ionic compound MgCl2.
Does KCI contain a coordinate covalent bond?
KCl is an ionic compound. Potassium is a group 1 ion and so is charged (+) and Chloride is a group 7 ion, and is consequently oppositely charged (-); the result is an ionic bond in exactly the same way that sodium binds with chloride to make NaCl.
Is NaCl polar covalent?
To classify a bond as polar or covalent, you must first find the Electronegativity difference. The electronegativity of Na is 0.93 and Cl is 3.16. Therefore we find the electronegativity difference by subtracting: 3.16 - 0.93= 2.23. Therefore NaCl is an ionic bond. For electronegativity differences >1.7, the bond is ionic. For electronegativity differences between 0.4-1.7, the bond is polar covalent For electronegativity differences < 0.4, the bond is non-polar covalent.
What is one way sodium and chlorine are different?
A chemical difference is that sodium reacts with water to make an alkali, and chlorine plus water give acids. A physical difference is that sodium is a solid at room temperature and chlorine is a gas.
What is the difference between chlorine and sodium chlorine?
Sodium chloride is the chemical way of writing it whereas chlorine sodium is simply listing the names of the atoms in the combination. When you name a compound, you name the anion followed by the cation. In this case Sodium (Na) is the anion and Chlorine (Cl) is the cation. So when you combine the two atoms you get Na+Cl->NaCl or Sodium Chloride.
