Is the atomic number the number of electrons? The atomic number uniquely identifies a chemical element. It is identical to the charge number of the nucleus. In an uncharged atom, the atomic number is also equal to the number of electrons. The sum of the atomic number Z and the number of neutrons N gives […]
Can dolphins kill you?
Can dolphins kill you? THEY may have a reputation for being friendly, cute and curious creatures, but dolphins can also be extremely vicious – and attacks on humans are on the rise.

What is the physical property of filtration?
What is the physical property of filtration? Physical separation methods, such as filtration and distillation, are based on the difference in particle size and on the boiling point of the substances in the mixture, respectively. These are properties that can be observed and measured without changing the material itself. What kind of mixture can be […]
Which two scales are used to measure the temperature?
Which two scales are used to measure the temperature? The three most common temperature scales are Fahrenheit, Celsius, and Kelvin.

What is the inverse of tan?
What is the inverse of tan? Inverse tan is the inverse function of the trigonometric function ‘tangent’. It is used to calculate the angle by applying the tangent ratio of the angle, which is the opposite side divided by the adjacent side of the right triangle. Based on this function, the value of tan 1 […]
