Aluminum has it's valence electrons in the 3rd energy level. Others that also have valence electrons in n=3 would be Na, Mg, Si, P, S, and Cl. Argon also has a filled 3rd level.

What do elements in each period have in common?
they have the same energy levels
How can you determine the number of energy rings an atom has by looking at the periodic table?
The number of energy levels is equal to the period number of the element. Through a group, the number of energy levels increases. All the elements in a period has the same number of energy levels.
What are the rows called in the periodic table?
Rows in the Periodic Table are called Periods.There are 7 periods in total.All the elements in period have same number of energy levels.
A horizontal row of elements is called a?
On the Periodic table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
Are energy levels the same as the period number?
no
What do elements in each period have in common?
they have the same energy levels
Why are elements put in rows?
all elements in one period have the same number of energy levels
Same elements are highly what because their outermost energy levels are only partially filled?
reactive
What is similar for elements located next to one another on the periodic table?
Elements in the same period (row) have the same number of electron shells or energy levels
How can you determine the number of energy rings an atom has by looking at the periodic table?
The number of energy levels is equal to the period number of the element. Through a group, the number of energy levels increases. All the elements in a period has the same number of energy levels.
Elements across a series have same number of?
Elements across a series have the same number of atomic energy levels. An elemental series is better known as a period.
What do you notice about the number of energy levels in an atom of an element in the period the element is in?
The atom of an element in the third period of the Periodic Table has 3 energy levels and so on. Also, atoms of elements in the same group have the same no. of valence electrons.
What do you notice about the energy levels in an atom of an element and the period the element is in?
the period number tells which is the highest energy level occupied by the electrons
What do all elements in the same period on the period the periodic table have in common?
A. They have the same number of protons.B. They have the same number of orbitals.C. They have the same number of electrons.D. They have the same number of neutrons.
Which element has the same number of energy levels as aluminum and the same number of valence electrons as calcium?
1. An element contain only specific atoms of this element and no other atoms. 2. Compounds as calcium aluminates contain both aluminum and calcium.
Rows of elements are called?
On the Periodic Table, horizontal rows are given the technical term "periods", while vertical columns are called "groups". Elements in the same period are similar in that they have the same number of energy levels.
Is electrons the only thing arranged in various energy levels or orbitals or are protons arranged the same way?
There are nuclear energy levels, but they're not "the same" as the electronic energy levels.
