The sugar and phosphate group of nucleotides never change. There are four possible nitrogenous bases and thus it is the only part of nucleotides that can change.
The number of protons MUST remain the same for it to be the same element. It is the number of protons that DEFINES the element.
The number of protons is what identifies an element.
atomic number
The Atomic Number never changes
the number of protons in its nucleus
mkkk
if the number of protons changed, the atom would become a different element
how will the electron configuration of the atom change when the atom becomes an iron
What element the atom is is defined by the number of protons it contains in the nucleus. This is the same for most of the chemical properties. If an atom has a different number of neutrons from the norm it is called an ion, and it is usually a lot more unstable than a regular atom of its type, however most of the rest of the chemical properties stay the same.
The atom would stay the same size because it would still have the same amount of energy levels. The mass of the atom would be slightly less though.No, an atom shrinks when loosing an electron.There are less electrons ('-'charges) left that are attracted by the same number of protons ('+'charges) in nucleus, so the atraction per electron is stronger.
Atoms are neutral as long as they contain the same number of protons as electrons. If there are more electrons than protons, the atom has a negative charge. If there are less electrons than protons, the atom has a positive charge.

The element won't stay the same because the element is determined by its number of protons. The number of protons is also the atomic number.
For the most part, yes the quantities of each are different. Light nucleii can have the same number of protons and neutrons and be stable enough to stay the same element (deuterium = 2H, 4He, 6Li , 10B, 12C, 14N, 16O, 20Ne, 24Mg, 28Si, 32S, 36Ar, 40Ca are stable), but a nucleus of a given element can sometimes have more or less neutrons, and be stable. Tin is the heaviest nucleus that has an isotope where #p = #n, and this isotope is very unstable

covalent bonds are when one atom shares the same valence electrons with another atom other.Covalent bonds are how atoms stay together

The isotope of an element is the different versions of that element. Due to the different number of neutrons. So the same element can have different numbers of neutrons in it's nucleus and therefore different mass numbers e.g. Chlorine 35 or Chlorine 37. Both contain identical numbers of protons but different numbers of neutrons.
An isotope is an atom with a different number of neutrons. The number of neutrons is the only particle that changes. Electrons will stay the same. Therefore, the number of electrons is the same as the atomic number, which is 18.
well, protons, neutrons and electrons react to each other, so I'm thinking that they make different things when a certain number of them connect in their own connection. they stay the same when they want to become stable atoms and join up with other electrons that belong to a different atom, because the "borrowed" electron doesn't really belong in that atom so the element stays the same. Hope my answer works for you curiosity driven people:)!
