Why do different isotopes of an element generally have the same physical and chemical properties?
tresset_1 [31]

Answer:

The correct answer is because they have same number of protons but different number of neutrons.

Explanation:

Isotopes are atoms of the same element but differ only in the number of neutrons in the nucleus, i.e. they have same atomic number but different mass number.

Mass number is affected as they have different number of neutrons, thus effecting their physical properties.

The number of electrons and protons are same, i.e. their atomic number is same and thus their chemical properties are same as chemical properties are determined by the atom’s electronic configuration and that relates to number of protons.

The specific heat of a substance is the heat that must be absorbed to increase the temperature of 1 gram of a substance by 1 deg
Vlad1618 [11]

Answer:

True.

Explanation:

Specific heat is the amount of heat required to raise one gram of a particular substance by one degree Celsius or Kelvin.

Formula for calculating specific heat is the amount of heat absorbed or released = mass x specific heat x change in temperature.

= m * Cp * delta T
