Bromine is in Group 7. How many electrons are in the outer shell of a bromine atom?
(a)
In the periodic table, the (a) number tells us the number of electrons in the outer shell of an atom.
Placing the elements in order of atomic weight was incorrect because some elements have (a) that have different masses.
How did Mendeleev overcome some of the problems in his version of the periodic table?
He made up new elements to fill in gaps.
He left gaps for undiscovered elements.
He ordered the elements in terms of atomic mass.
He placed elements in groups according to similar properties.
In the periodic table, the (a) number tells us the number of electron shells in an atom.
What were some problems with the early versions of the periodic table?
Some elements had not been discovered so the tables were not complete.
The elements did not follow a regular pattern.
