Elements in increasing electronegativity krypton strontium lead bromine copper cesium

HI!

The correct order would be:

(least electronegative) Cesium -> Strontium -> Copper -> Lead -> Bromine -> Krypton (most electronegative)

Electronegativity is that chemical property of an atom that describes its tendency/ability to attract an electron to itself. The higher the electronegativity of the atom, the more its tendency to attract an ion to itself, increasing the likelihood of forming a negative ion in a compound. The difference in the electronegativity values of two atoms forming a compound can help indicate the type of bond that will form between them: covalent or ionic. If the difference is greater than 2, the bond found to be ionic.

The electronegativity values of the atoms in the question are as follows:

CsCesium0.79

SrStrontium   0.95

CuCopper1.90

PbLead2.33

BrBromine2.96

KrKrypton3.00

Hope this helps!

answer: any goods being imported from another country may be subject to issued by the federal government are tariffs

explanation:  

tariffs are a tax on anything that are imported from abroad. government use them to protect and boost their local industries and the thought is that they encourage consumers to buy local instead of importing and they will hope will protect jobs and economy in the country that implements them
