What are patterns in the periodic table?
These are the patterns of the periodic table across the period. 1. The atomic radius reduces as we move across a period from left to right, 2. The ionization energy increases as we move across a period. 3. The electron affinity decreases as we move across a period. Learning them enables us to have a clear view of elements in the periodic table.
How many rows or periods are in the periodic table?
Th horizontal rows are referred as periods. There are 7 periods in Periodic Table.
What do the columns of the periodic table tell us about those elements?
The columns of the periodic table are called groups (or families). All elements in a group have the same number of electrons in their outer orbital. Furthermore, since many chemical properties are determined by the location of the outermost electrons, elements in the same group will share many common properties.
Why do you need to learn the periodic table?
The periodic table should be memorized because it will make you know the symbols without searching for them all of the time. If you are in school, it is very likely that you will be tested on the table.
What is the relationship between an atom's location on the periodic table and how it bonds?
- atomic number of an element - group and period of an element - the most common valence - the reactivity of an element - the state of matter of an element - natural or artificial elements - an evaluation of chemical and physical properties - gases, metals, metalloids etc.
What do periods tell you in the periodic table?
The periodic table tells you all the known elements know to us. I dont think there is such a thing as periods.
What does each row in the periodic table tell us?
The rows (periods) work out to be the energy levels, ex. if an element is in period 5, it has 5 energy levels.
What are the orientation of elements in the peridoc table tell us the arrangement of the what?
The periodic table is in order of atomic mass

Learning them enables us to have a clear view of elements in the periodic table.
What direction do periods run and what do they tell us in a periodic table?
They run from left to right
What columns in periodic table tell us about the atom?
How many valence (outer shell) electrons an element has.
How many rows or periods are in the periodic table?
Th horizontal rows are referred as periods. There are 7 periods in Periodic Table.
What do the columns of the periodic table tell us about those elements?

Furthermore, since many chemical properties are determined by the location of the outermost electrons, elements in the same group will share many common properties.
What does the atomic tell us?
it tells us the number on the Periodic Table and it also tells us how many protons and nuetrons and electrons are in the atom within the nuecles.
Three elements are in the same column of the periodic table what does this tell us?
it tells us that their chemical properties are similar, and in many cases follow a trend.
What do you use the periodic table for?
we use the periodic table because it helps us with the atoms and electrons it tells us the mass number atomic number and the symbol
Write a sentence that describes the purpose of the periodic table?
The elements of the periodic table are arranged in groups and periods. All of the elements in a period have the same number of atomic orbitals where as in a group all the elements have the same number of valence electrons.
