Chemistry

A:

Water has numerous physical properties, including the color, surface tension and adhesion. There are far more physical properties than chemical properties. This is partially due to water taking so many forms, such as ice or steam; each form of water has different properties.

  • Why do elements tend to form compounds?

    Q: Why do elements tend to form compounds?

    A: The fact that some elements are more atomically stable than others accounts for their tendency to form compounds. This atomic stability is basically the amount of electrons an atom holds in its outer shell. When the outer shell is completely full, an atom is more stable than when the outer shell is only half full.

  • What is anomalous expansion of water?

    Q: What is anomalous expansion of water?

    A: The anomalous expansion of water is an abnormal property of water whereby it expands instead of contracting when the temperature goes from 4oC to 0oC, and it becomes less dense. The density becomes less and less as it freezes because molecules of water normally form open crystal structures when in solid form.

  • How was the proton discovered?

    Q: How was the proton discovered?

    A: The proton was discovered by Ernest Rutherford through the gold foil experiment, says the Purdue University College of Science. The results of the experiment led Rutherford to conclude that the positive charge and the mass of an atom are concentrated in a tiny fraction of the overall volume. In 1920, Rutherford proposed that the positively charged particle in an atom’s nucleus be called a proton.
