Which of the following statement(s) are true about the atoms of any element?
Sunny_sXe [5.5K]

Answer: The answers are:

The number of protons in an atom of an element is unique to each element.

A proton in an atom of one element is identical to a proton in an atom of another element.

Explanation: The number of protons in an atom of an element is unique to each element. The number of protons in an atom of an element is the atomic number of that element. Atomic number determines the chemical properties and reactivity of the atom.

All atoms are made up of three particles: protons, electrons and neutrons. These particles are identical in all the elements, what distinguishes one element from another is the number of each of these particles it contains. Therefore, a proton in an atom of one element is identical to a proton in an atom of another element likewise the electrons and neutrons.

What type of experiments can be carried out to determine the spontaneity of a reaction? Does spontaneity have any relationship t
Alexeev081 [22]

Answer:

Following are the responses to this question:

Explanation:

They can measure the spontaneity of the reaction with the form,\Delta G =\Delta H - T \Delta S Substituting the values of \Delta H, T,\ and \  \Delta S in the above expression information mostly on the playfulness of the reaction would be given to us from the expression above. This reaction is spontaneous if the price of \Delta G is negative, and if it is positive the response is not random. At equilibrium, the values of \Delta G, \Delta H, \ and \ \Delta S are 0.

30. a. How do the properties of metals differ from those
Ahat [919]

Explanation:

Metals are elements that ionized by loss of electrons.

Ionic and molecular compounds are usually non-metals.

Properties of metals:

  • Metals have free mobile electrons and the metallic bonding ensures that.
  • They are usually electropositive and freely looses their electrons.
  • None of the metal is soluble without a chemical change occurring.
  • They are ductile and malleable.
  • Metals are good conductor or heat and electricity in their free uncombined state.
  • They are lustrous.

B. The specific property of metals accountable for their unusual electrical conductivity is due to the presence of free mobile electrons in their lattices.
