Part of one row of the periodic table is shown. which element’s atoms have the greatest average number of neutrons? tin (sn) antimony (sb) tellurium (te) iodine (i)

Number of neutrons can be calculated as = mass number-atomic number

so for all these elements, no. of neutrons will be calculated as:

For tin(Sn),

number of neutrons= 119-50

=69

For antimony(Sb),

No. of neutrons=122-51

=71

For Tellurium(Te),

No. of neutrons=128-52

=76

For iodine(I),

No. of neutrons= 127-53

= 74

So tellurium will have highest number of neutrons

tellurium (Te)

Explanation:

hey there!

boiling point is the temperature at which the vapor pressure of the liquid equals atmospheric pressure. the vapor pressure of solvent molecules is decreased when a solute is added, so a higher temperature is required to increase the number of solvent molecules in the gas phase above the liquid.

at the freezing point, the vapor pressures of the solid and liquid are equal; a lower temperature is needed to reduce the number of solvent particles above the liquid.

hope this you
