What are valence electrons?
Any of an atom's electrons

The periodic table is a chart that organizes the elements based on their atomic properties. Elements in the periodic table are organized according to the periodic law. The periodic law states that chemical and physical properties of elements are periodic functions of their atomic numbers (the number of protons in the nucleus). As the atomic number of elements increases, different elements display similar characteristics at regular intervals.
Periodic law states that elements are arranged _______________________________________________________________.
in alphabetical order.
from largest to smallest.
as periodic functions of their atomic numbers.
there is no rhyme or reason.
In 1869, Dmitri Mendeleev developed the first periodic table, organizing the elements according to atomic weight. When he ordered the elements, he noticed that there were patterns of repeating properties. The modern periodic table sequences elements from left to right by atomic number.
This was the first person to organize a periodic table.
Neils Bohr
Dmitri Mendeleev
Democritus
Ernest Rutherford
The elements in groups 3-12 are called the transition metals. These are similar to the metals in that they are flexible and good conductors but different in that they have unique valence electron structure. They typically form coordinate complexes in which one atom is surrounded by several more in a large complex. Iron, gold, and copper are examples of transition metals.
Which group are the transition metals most like?
Metals, they are flexible and good conductors.
Non metals, they a unique valence electron structure.
Noble gases, they don't want to bond with anything else.
They are like both metals and non metals in some ways.
