Which element has the greatest average atomic mass? iodine bromine tellurium krypton

Answer is: tellurium.

Tellurium is a chemical element with symbol Te and atomic mass of 127.60 g/mol.

Iodine is a chemical element with symbol I and atomic mass of 126.90 g/mol.

Krypton is a chemical element with symbol Kr and atomic mass of 83.79 g/mol.

Bromine is a chemical element with symbol Br and atomic mass of 79.90 g/mol.

Atomic mass of Iodine = 126.90447 g/mol

Atomic mass of Bromine = 79.904 g/mol

Atomic mass of Tellurium = 127.6 g/mol

Atomic mass of Krypton = 83.798 g/mol

Thus Tellurium has the greatest average atomic mass.

plants need sunlight, water, and carbon dioxide to make food. plants use the raw materials of water, nutrients they absorb from soil, and carbon dioxide to make sugars the plant can use. energy from the sun and chlorophyll are also needed.

water at room temperature is flowing through a pipe with pressure taps located 10 ft apart along one section of the pipe, which are connected to a mercury (s=13.6) manometer.
