Why zinc is not a noble gas?

Why zinc is not a noble gas? A valence subshell is one which can react to form a bond. So the definition of valence orbitals doesn’t depend on their quantum numbers, but on the energy required to fill them. That’s why zinc is not a noble gas – the 4p orbitals count as valence (reactive) […]

What are the disadvantages of digital thermometer?

What are the disadvantages of digital thermometer? The advantages of digital thermometers are that they are inexpensive, easy to read, require very little maintenance and give an accurate reading. The disadvantage is that they get damaged easily if dropped and the battery powering them eventually runs out. What is the advantage of digital thermometer over […]

What is the dimension of surface tension sigma?

What is the dimension of surface tension sigma? Surface Tension (T) = Force × Length-1. Or, T = [M1 L1 T-2] × [L-1] = M1 T-2. Therefore, surface tension is dimensionally represented as M1 T-2. What is surface tension explain with example? Surface tension, property of a liquid surface displayed by its acting as if […]

How do you find the number of neutrons?

How do you find the number of neutrons? For all atoms with no charge, the number of electrons is equal to the number of protons. The mass number, 40, is the sum of the protons and the neutrons. To find the number of neutrons, subtract the number of protons from the mass number. What is […]

What is more accurate than a stopwatch?

What is more accurate than a stopwatch? Far more accurate than quartz crystal oscillations are an atomic time clock. With an error of only 1 second in up to 100 million years, atomic clocks are among the most accurate timekeeping devices in history. How fast can you stop a stopwatch? The Right Answer wrote: 0.05 […]

What are the 5 non-renewable resources?

What are the 5 non-renewable resources? Nonrenewable energy resources include coal, natural gas, oil, and nuclear energy. Once these resources are used up, they cannot be replaced, which is a major problem for humanity as we are currently dependent on them to supply most of our energy needs. What is good about non-renewable resources? The […]

How do you know if tubes are open or closed?

How do you know if tubes are open or closed? Open and closed ends reflect waves differently. The closed end of a tube is an antinode in the pressure (or a node in the longitudinal displacement). The open end of a tube is approximately a node in the pressure (or an antinode in the longitudinal […]
