What is quantum number explain with example?
What is quantum number explain with example? A quantum number is a value that is used when describing the energy levels available to atoms and molecules. An electron in an atom or ion has four quantum numbers to describe its state and yield solutions to the Schrödinger wave equation for the hydrogen atom. ms or […]
Is there forces of attraction among the particles in all matter?
Is there forces of attraction among the particles in all matter? Particles of matter of the same substance, such as the same element, are attracted to one another. The force of attraction tends to pull the particles closer together. The particles need a lot of kinetic energy to overcome the force of attraction and move […]
Why is element 43 unstable?
Why is element 43 unstable? Technetium can only be produced artificially because most forms or isotopes of it (atoms of the same chemical element with different numbers of neutrons) have an excess of neutrons, making it very unstable. Why is technetium so weird? Technetium, with atomic number (denoted Z) 43, is the lowest-numbered element in […]
Why is liquid water important to life?
Why is liquid water important to life? Even organisms that live in very dry places need water to live. One reason that water is so important is because it’s a liquid. This means that it can move around the materials that are needed for chemical reactions. These reactions include the ability for cells to get […]
