Question
The atomic number tells you the number of neutrons in the nucleus. number of protons in the atom. atomic mass of the atom. number of its electrons if the atom is neutral. Both b and d are correct. Isotopes differ in their number of protons. atomic number. number of neutrons. number of electrons. The periodic table provides us with what information? the atomic number, symbol, and mass how many shells an atom has how many electrons are in the outer shell All of these are correct. Which of the subatomic particles contributes almost no weight to an atom? protons in the electron shells electrons in the nucleus neutrons in the nucleus. electrons at various energy levelsExplanation / Answer
1. The atomic number tells you the: Both b) and d)
Because, atomic number represents the number of protons and when there are same number of protons (+ve charged) are equal to electrons (-ve charged) then the net charge on atom is zero and thus atomic number represents number of its electrons if the atom is neutral.
2. Isotopes differ in their in number os neutrons.
An isotope of an element contains the same number of electrons and protons but differs in the number of neutrons. Thus Isotopes have same atomic number but have different atomic mass. E.g. Hydrogen (atomic number 1, atomic mass 1) and deuterium (atomic number 1, atomic mass 2).
3. The periodic table provides us with what information? : The atomic number, Symbol, and mass
4. Which of the subatomic particles contributes almost no weight to an atom: Electrons at various energy levels.
