What is a row in a the periodic table called?
A row of the periodic table is known as a period.Related Information:Across a period, you can see how the electrons fill the energy levels from the s sub-level to the p sub-level. The highest-filled energy levels correspond to the row, or period, number. Down a group, you can see how many valence electrons are present in the atoms of each element.
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons
Which direction do periods go on the periodic table?
In the periodic table of the elements, a period is a horizontal row of the table. Elements in the same period have the same number of energy levels.
What is the trend in ionization energy of period 3 elements on the periodic table?
The trend in ionization energy of period 3 elements on the periodic table generally increases from left to right.
What happens to the pull on the electrons in the Periodic Table?
The pull on electrons in the Periodic Table increases from left to right across a period due to increasing effective nuclear charge. From top to bottom within a group, there is less pull on the electrons as electrons are added to higher energy levels further away from the nucleus.
What happens to the reactivity of left to right across the periodic table?
Across a period, as we move from left to right, the electronegativity increases in the periodic table.
What happens to the first ionization energy of the elements as a period is crossed?
Moving from left to right across a period, the first ionization energy increases because it becomes increasingly difficult to remove an electron.
What happens to the elements masses from left to right on the periodic table?
increases

The highest-filled energy levels correspond to the row, or period, number. Down a group, you can see how many valence electrons are present in the atoms of each element.
How can you find an element?
I'm assuming you mean "how can you find an element on the periodic table?" The periodic table is strategically placed. You can either look for the atomic number (the number at the top-- the number of the protons in one atom), or you can just look for the Element Symbol. The periodic table from left to right is sorted by increasing atomic number. The periodic table from top to bottom is sorted by increasing number of energy levels (the levels in which the electrons are in).
How many and where are the periods of the periodic table located?
The periodic table consists of 7 periods. These periods are arranged horizontally from left to right. Each period represents the energy levels or shells that electrons occupy around the atomic nucleus in an atom.
What happens to to the number of energy levels or shells as you move from left to right across rows or periods in the period table?
As you go down the horizontal rows, the energy levels increase.
What increses in the periodic table?
As you move from left to right across a period in the periodic table, the atomic number increases. This means there is an increase in the number of protons in the nucleus of the atoms. Additionally, as you move down a group or family in the periodic table, the number of energy levels or electron shells increases.
What happens to the mass number as you move from left to right in the periodic table?
It increases
What does the period number tell about the energy levels ocupied by electrons in an atom?
The period number tell about the energy levels occupied by electrons
What happens to the atomic radius as you move down the periodic table?
Down a group, the atomic radius increases as the number of shells or energy levels increases.
What periodic treds exist for ionization energy?
Ionization energy increases to the right and up on the periodic table. Ionization energy is the energy required to remove an electron. It can be conceptualized as the opposite of electron affinity, though this is not precisely true.
