The atomic number of an element tells the?
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
How do the number of protons compare to the number of electrons in an atom with a neutral charge?
The numbers of protons and the numbers of electrons balance; they are equal.
What does the group number A elements (in the AB numbering system) tell about valence electrons?
The group number tells you the number of valence electrons present.
What does the group number of A elements (in the AB numbering system ) tell about valence electrons?
The group number tells you the number of valence electrons present.
What does the period tell you about electrons?
The period tells you how many energy levels an atom has.
The atomic number of an element tells the?
atomic number tells us the number of protons and electrons in the given atom. As Atomic No. = no. of protons = No. of electrons
What tells you how many protons and electrons an element has?
The atomic number = Number of protons = Number of electrons
What does the number tell you?
the periodic number tells you the number of electrons and protons.
What is number of electrons in chlorine?
To find this out, we'll look at a period table to find chlorine's atomic number. This tells us its number of protons, which, as it turns out, is 17. We know that protons and electrons carry equal but opposite charges, so to balance the net charge of chlorine back to 0, it must have 17 electrons.
How do you tell how many electrons an element has?
The number of electrons should balance the number of protons, which is denoted by the atomic number.
What does the atomic number tell you about the element?
it tells you the number of protons and electrons
What does an atomic number tells you?
The atomic number tells you the number of protons in the nucleus. As such, it defines the element, since each element has a definite and defined number of protons. In the element, it also tells you the number of electrons, since the element (not the ion) has a neutral charge and protons = electrons.
What tells how many protons an element has?
The atomic number = Number of protons = Number of electrons
How do the number of protons compare to the number of electrons in an atom with a neutral charge?
The numbers of protons and the numbers of electrons balance; they are equal.
What does the group number of A elements (in the AB numbering system) tell about valence electrons?
The group number tells you the number of valence electrons present.
What does the group number A elements (in the AB numbering system) tell about valence electrons?
The group number tells you the number of valence electrons present.
What does the group number of A elements (in the AB numbering system ) tell about valence electrons?
The group number tells you the number of valence electrons present.
