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.

What do elements in the same period have in common?

Elements in the same period are those that are in a single horizontal line from left to right. They do not share the same type of chemical reactivity as seen in groups. They only real thing that these elements share in common is the same principal quantum number, or main energy shell.

How many shells do the elements in a period have?

Elements in a Period Have how many shells for the Electrons in Common. eg. period 3 elements all have 3 shells. The number of electrons in a shell goes like this:

What are the characteristics of modern periodic table?

Modern periodic table consist of groups and periods. The vertical columns are called groups. The elements which are in the same groups have the same number of valence electrons (i.e same number of electrons in the outermost shell). Also they possess almost similar properties. Yes there are also few exceptions in the elements of d-block and f-block.

What is the difference between period and family on the periodic table?

Period - a horizontal row on the periodic table - there are 7 rows Family/Group - a vertical column on the periodic table - there are 18 vertical columns What do elements in the same family/group have in common? Elements in the same group/family have similar chemical and physical properties. **They also have the same number of valence electrons.

Which elements have similar physical properties?

Which group of elements has the same number of valence electrons?

What are the vertical columns in the periodic table called?

Elements in a period have same - Toppr Ask

Elements present in horizontal rows are called periods. Elements belonging to the same period have same no. of the shell as the electrons are added in the same shell of the element.

Why do some periodic tables have 18 groups while others have 8?

In school I have been taught about the periodic table with 8 groups, representing the number of electrons in the outer shell (with exceptions). But online almost all I can find is periodic tables w...

Which elements have similar physical properties?

For example, Group 1 elements (lithium, sodium, potassium, rubidium, cesium and francium) have similar physical properties like, metallic luster, softness , etc. Also they have similar chemical properties. For example, all the alkali metals (group 1 elements) are highly reactive to water. Thus all the elements of group 1 have the same number ...

Which group of elements has the same number of valence electrons?

Elements of group 17 are highly electronegative and have higher ionisation enthalpy. They react with water and form halides. Thus all the elements of group 17 have the same number of valence electrons (i.e 7) and they show common properties.

What are the vertical columns in the periodic table called?

Modern periodic table consist of groups and periods. The vertical columns are called groups. The elements which are in the same groups have the same number of valence electrons (i.e same number of electrons in the outermost shell). Also they possess almost similar properties.

How many valence electrons does each element have?

All the elements of 1st group (H, Li, Na, K, Rb, Cs, Fr) have one valence electron.

How many electrons are in the 13th group?

All the elements of 13th group have 3 electrons in its outermost orbit.

How many electrons are in the outer shell of a 14th group?

14th group elements have 4 electrons in outer shell, not 14.

Which electrons participate in chemical reactions?

Thus electrons of both s-orbitals as well as d-orbitals participate in chemical reaction.

Which elements have similar physical properties?

For example, Group 1 elements (lithium, sodium, potassium, rubidium, cesium and francium) have similar physical properties like, metallic luster, softness , etc. Also they have similar chemical properties. For example, all the alkali metals (group 1 elements) are highly reactive to water. Thus all the elements of group 1 have the same number ...

Which group of elements has the same number of valence electrons?

Elements of group 17 are highly electronegative and have higher ionisation enthalpy. They react with water and form halides. Thus all the elements of group 17 have the same number of valence electrons (i.e 7) and they show common properties.

What are the vertical columns in the periodic table called?

Modern periodic table consist of groups and periods. The vertical columns are called groups. The elements which are in the same groups have the same number of valence electrons (i.e same number of electrons in the outermost shell). Also they possess almost similar properties.

How many valence electrons does each element have?

All the elements of 1st group (H, Li, Na, K, Rb, Cs, Fr) have one valence electron.

How many electrons are in the 13th group?

All the elements of 13th group have 3 electrons in its outermost orbit.

How many electrons are in the outer shell of a 14th group?

14th group elements have 4 electrons in outer shell, not 14.

Which electrons participate in chemical reactions?

Thus electrons of both s-orbitals as well as d-orbitals participate in chemical reaction.
