What does atomic number tell you?
Tell you the number of protons and electrons in an atom
What do the atomic number and the mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
What do the atomic number and mass number tell you about the atom?
the atomic number is the number of protons/electrons in the atom
What does the outer shell of electrons of an atom tell you?
The electrons on the outermost shell of an atom tell you how many valence electrons an atom on the periodic table has , and this number can be used to apply to the octect rule .
If you know the number of electrons in a neutral atom can you determine what the element is?
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
How do you tell the number of neutrons in an element?
Subtract the atom number from the mass number to get the neutron. Mass number is the sum of neutrons and electrons. Atom number is the number of electrons. the number of electrons is equivalent to the number of protons.
What does the period number tell about the energy levels occupied by electrons in an atom atom?
the period number tells which is the highest energy level occupied by the electrons
What is the atomic number of an element?
The atomic number is the number of protons in the nucleus of an atom of an element. An element that is in its neutral state has the same number of protons and electrons, thus the atomic number can also be used to tell the number of electrons in a non-ionic atom of that element.
What does the period number tell about the energy levels occupies by electrons in an atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy level occupied by electrons in an atom?
the period number tells which is the highest energy level occupied by the electrons
What does the period number tell about the energy levels occupied by electrons in the atom?
the period number tells which is the highest energy level occupied by the electrons
You can tell how many protons an atom of a certain element has by that element's?
The atomic number = Number of protons = Number of electrons
