A period in the periodic table is a row of chemical elements. All elements in a row have the same number of electron shells. Each next element in a period has one more proton and is less metallic than its predecessor.

How are periods and groups different from one another?
A period is a horizontal row of the periodic table. A group is a vertical row of the periodic table.
Why do periods have different numbers of elements?
Elements in a period share the highest unexcited electron energy level. There are more elements in some periods than others because the number of elements is determined by the number of electrons allowed in each energy sub-level.
How does a family of elements differ from a period of elements?
The vertical columns on the periodic table are called groups or families because of their similar chemical behavior. All the members of a family of elements have the same number of valence electrons and similar chemical properties. The horizontal rows on the periodic table are called periods.
How are the elements in the same period similar?
Elements in the same period have the same number of electron shells; moving across a period (so progressing from group to group), elements gain electrons and protons and become less metallic. This arrangement reflects the periodic recurrence of similar properties as the atomic number increases.
What do elements in the same period have in common?
ll of the elements in a period have the same number of atomic orbitals. In other words they have the same number of valence electrons.
How are atoms of one element similar to and different from atoms of other elements?
The number of protons in an atom is the defining feature of an atom. It's what makes one element different from another. The number of protons in an atom is called its atomic number. Oxygen atoms have 8 protons.
Why do elements in the same group have similar properties?
In chemistry, a group is a vertical column in the periodic table of the chemical elements. ... Each element within a group has similar physical or chemical properties because of its atom's outermost electron shell (most chemical properties are dominated by the orbital location of the outermost electron).
Are elements more similar in groups or periods?
Explanation: The elements of a group have similar chemical properties but in a period they have different chemical properties. This is because the chemicals properties depend on no of valence electrons.
What elements have similar properties?
Two different elements have similar chemical properties when they have the same number of valence electrons in their outermost energy level. Elements in the same column of the Periodic Table have similar chemical properties.
Do elements in the same period have similar properties?
They exhibit similar chemical properties. Elements within the same period have different number of electrons in their valence shells (the number is increasing from left to right) and different valence shell electron configuration. Therefore, elements in the same period are chemically different.
Do all elements in a period have similar properties?
Yes - elements grouped in periods share similar chemical properties due to the similarities in their configuration of their outer-most electron valence shells.
Do elements in the same period or group have similar properties?
Each row of the periodic table is called a period and each column of the periodic table is called a group (or family). ... Elements within the same period or group have similar properties.
What does it mean if elements are in the same group?
The elements in each group have the same number of valence electrons. As a result, elements in the same group often display similar properties and reactivity.
Why don t elements in the same periods share the same properties?
4) Why don't elements in the same periods share many of the same properties? Elements in the same periods have electrons in the same energy level, but it turns out that the energies of the electrons is nowhere near as important as how much elements want to gain or lose electrons to achieve a full octet.
