Identify atoms that are isotopes in each of the following sets of four atoms.

Isotopes are elements with similar chemical properties meaning same atomic number, but varying atomic masses, meaning different number of neutrons in the element.  It can be easily determined knowing this and viewing the subscripts of the element symbol.  The lower subscript is the atomic number and the higher subscript is the atomic mass.  Simply look for similar atomic numbers and differing atomic masses in the sets.

a) 1, 2 are isotopes

b) 1, 3 are isotopes

c) 1, 2, 3 are isotopes

d) none are isotopes

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

convalent bond :

is a chemical bond formed by the sharing of electron between 2 atoms.

it is the direct chemical bond between 2 atoms.

in bond formation atoms are involved here.

electrovalent bond:

is a chemical bond defined as electroststic attraction between 2 atoms.

it is the electrostatic attraction between 2 atoms.

in bond formation, ions are involved here.

hope it

and ur welcm
