What does G pair with in DNA? The rules of base pairing (or nucleotide pairing) are: A with T: the purine adenine (A) always pairs with the pyrimidine thymine (T) C with G: the pyrimidine cytosine (C) always pairs with the purine guanine (G) Is DNA base 2 or base 4? DNA is more 2-based […]
Are cathodes positive?
Are cathodes positive? The anode is the electrode where electricity moves into. The cathode is the electrode where electricity is given out or flows out of. The anode is usually the positive side. A cathode is a negative side. Is cathode positive or negative in battery? The electrode of a battery that releases electrons during […]
What happens when two neutral charged objects are rubbed together?
What happens when two neutral charged objects are rubbed together? When an atom has an equal number of protons and electrons, the charges cancel each other and the atom is said to be neutral. Rubbed together in a dry environment, some items have lost electrons and become positively charged, while others have gained electrons and […]

What periodic trend is most important for determining metal reactivity?
What periodic trend is most important for determining metal reactivity? Metallic and Non-metallic Character Within a compound, metal atoms have relatively low attraction for electrons, as indicated by their low electronegativities. By following the trend summary in the figure below, you can see that the most reactive metals would reside in the lower left portion […]
