you can tell an atom's position in the peiriodic table by its valence electrons in the outermost shell.
potassium therefore has one free valence e-, placing it in group 1
depending on how many shells the atom has determines which rows (horizontal) it is in

How is the periodic table used to describe atomic structure?
The periodic table can be used to describe atomic structure by using the period to tell you how many shells (principle quantum number) there are in an element, and the group number can be used to tell you the number of valence electrons in the outermost shell.
What does the group tell us about the structure of the atom?
Atoms in the same group have similar structures.
How did Rutherfords gold foil experiment tell scientists about the atomic structure?
That atoms have a positively charged nucleus.
Give a balanced chemical equation for potassium and chlorine to produce potassium chloride?
Potassium chloride, KCl, is a metal salt. It is composed of one atom of potassium (K) and one atom of chlorine (Cl). Potassium is an alkaline metal from Group 1 in the periodic table, and chlorine is a halogen from Group 17 on the periodic table. All elements from Group 1 have a +1 oxidation state, and all elements from Group 17 have a -1 oxidation state. Elements from Group 1 will form one-to-one relationships with elements from Group 17.
What are three things that the periodic table can tell me?
the properties, the atomic number, and atomic mass

What is the need of atomic models?
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.
What does the group tell us about the structure of the atom?
Atoms in the same group have similar structures.
What does each periodic number in the periodic table tell about the atomic structure?
The atomic number is equal to the number of protons and the number of neutrons in that atom.
What did Rutherford's gold foil expieriment tell scientists about atomic structure?
That atoms have a positively charged nucleus.
How did Rutherfords gold foil experiment tell scientists about the atomic structure?
That atoms have a positively charged nucleus.
What is need of model of atoms?
Atomic models tell us about the structure of an atom which is based on what we know about how atoms behave. But it is not necessary that it will be a genuine picture of the structure of an atom.
How can you tell using the periodic table that sodium and potassium are similar?
You can tell by the location, and the fact that they are both in the same column. Elements in the same column (or group) have similar properties.
What does the group number of the periodic table tell you about the structure of an atom?
the group number,element in some way describes the number of valence electrons or the property that they exhibit
What does the number of nucleus tell you about the element?
The number of the protons in the nucleus of a chemical element is equivalent to the atomic number; the atomic number define the position of this element in the periodic table (group, period). And from these we can suppose the chemical properties of this element.

The atomic number of an element will tell you what?
Atomic number = Number of protons
