3 atoms I think.
all neutral atoms have same number of protons and neutrons
Atoms have 1 to 118 electrons. For a neutral atom the number of electrons is equal to the number of protons (atomic number).
2: A neutral atoms must have the same numbers of protons and electrons.
It depends entirely on what type of atom it is. (Neutral atom is redundant. A "non-neutral" atom is referred to as an ion) If it is an atom of carbon, for example, there are 6 electrons. Silicon, on the other hand, has 14 electrons.
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
Atoms are electrically neutral because they have an equal number of protons, which are positively charged, and electrons, which are negatively charged. This balance of positive and negative charges cancels each other out, resulting in an overall neutral charge for the atom.
Silicon-29 has 14 protons and 15 neutrons. Since atoms are electrically neutral, it will also have 14 electrons.
59, atoms have an equal number of protons and electrons, keeps the charge neutral
A neutral atom with 49 electrons will have 49 protons. The number of protons and electrons are always the same in a neutral atom. If the number of protons is not matched by the number of electrons, then the atom is charged and is called an ion. Further, if protons outnumber electrons, the atom is positively charged and is a positive ion. For situations where electrons outnumber protons, the opposite is true. The element with 49 protons in it is indium, by the way.
The number of electrons should = the number of protons.
Atoms are built form 3 types of particles Electrons (which are electrically negative) Neutrons (which are electrically neutral) Protons (which are electrically positive) Nature likes things to be balanced so when atoms are put together, nature makes sure that the number of Electron the atom has is matched by the number of Protons. This makes all atoms electrically neutral. However, when atoms react with each other chemically, they can share or swap electrons with each other which means that they are no longer electrically neutral (in this state they are called "ions"). Nature therefore requires that the stuff they have made (called a compound) when joining together is, overall electrically neutral and bonds them together so that this is achieved. This is why chemical compounds exist and are stable.
24 protons and 24 electrons
