The elements in the same group has
similar number of valence electrons
. They have identical number of electrons in their outermost shell. e.g. All the alkali metals in Group 1 have 1 valence electron, so they all tend to react the same way with other substances.
Does elements in the same group have the same properties?
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).
What properties do elements in the same group have in common?
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.
What properties are generally the same for elements within the same group quizlet?
Elements in the same family have similar properties because they
have the same number of valence electrons
.
What similar properties do elements in the same period have?
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.
Why do elements in the same group show similar properties but the elements in different groups show different properties?
Elements of a particular group
have similar electronic configurations and the same number of valence electrons in their atoms
. Hence, all the elements belonging to a certain group show similar properties. … Different groups have different valencies. Therefore, elements in different groups show different properties.
Why do elements in same family generally have similar properties?
Because the members of each
group in the main group elements has the same number of valence electrons
, there are similar properties and similar trends in chemical reactions found in the group.
What is similar about each element in a group?
The elements in a group have similar
physical or chemical characteristics of the outermost electron shells of their atoms
(i.e., the same core charge), because most chemical properties are dominated by the orbital location of the outermost electron.
What two 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.
What do elements in the same periodic group always have in common?
What do elements in the same group have in common? They have
similar chemical properties and the same number of valence electrons
.
Do elements in the same period or the same group have similar chemical and physical properties?
Yes – elements grouped in
periods share similar chemical properties
due to the similarities in their configuration of their outer-most electron valence shells.
Why do elements in a group have similar properties while in period varies?
Periodic Classification of Elements. … a) Elements in the same group have similar properties because
they have the same number of valence electrons in their outermost shell
. b) Elements in the same period have different properties because the number of valence electrons in their outermost shells differ.
What are the similar properties found among the members of same group?
The elements in a given group possesses
similar electronic configuration
, as the number of electrons in the respective outermost shells is the same. So, they have similar physical and chemical properties.
Why do elements in a group show similar properties?
A vertical column in the periodic table of elements is called group. … So, we can say that elements in a group have the same physical and chemical properties
because their atoms have the same number of valence electrons or same valence shell electronic configuration
.
Why the properties of elements are repeated after 2 8 18 and 32 elements?
The electronic configurations are repeated because 2, 8, 18 and 32
are the maximum number of electrons that can be placed in the four atomic shells, namely, K, L, M and N
.
How does metallic character change when we move I down a Group II across a period?
Across a period the atomic size decreases from left to right so the force of attraction between the nucleus and electron increases. hence the elements across a period cannot lose electrons easily. So,
metallic character decreases
across a period. So metallic character increases in a group.
What are properties of elements in the same group or family?
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
.
How do you know which element has similar properties?
Rows and Periods
Atomic number describes the number of protons in one atom of that element. For example, an atom of oxygen contains 8 protons. Elements are listed in order of increasing atomic number from left to right. …
Elements within the same period or group
have similar properties.
How are elements in the same family different?
Element families are elements
that have the same number of valence electrons
. Most element families are a single column of the periodic table, although the transition elements consist of several columns, plus the elements located below the main body of the table.
Do elements in the same period have more or less in common than elements in the same group?
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 do elements in the same group have in common quizlet?
Elements in the same group have
similar Physical and Chemical properties
, they also have the same number of electrons in their outermost shell, the valence shell.
