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: option (4) is the correct answer.

explanation:

areas which are at low altitudes and near the equator tend to receive direct sunlight from the sun. hence, heat energy or radiations from the sun make these areas warmer and they have warmest water.

whereas areas which are at high altitudes and away from the equator do no receive direct sunlight. hence, no direct contact from the sun makes these regions colder and thus, they have colder water.

thus, we can conclude that the statement areas at low latitudes near the equator have the warmest water because they receive the most direct sunlight best explains the relationship between an area's geography and the temperature of its surface water.
