What is the pattern of outer shell electrons in a group?
In a group, elements have the same number of outer shell electrons, which corresponds to the group number. For example, elements in Group 1 have 1 outer shell electron, elements in Group 2 have 2 outer shell electrons, and so on. This pattern helps determine the reactivity and chemical properties of elements within the same group.
The atoms of the elements in Group 2 have the same?
The atoms of elements in Group 2 have the same number of valence electrons, which is 2. This gives them similar chemical properties, such as forming 2+ cations in reactions.
How are the atoms of the elements in group 2 the same?
They share the same number of electrons (=2) in the valence shell: they have the same oxidation state of +2
Do the elements ba and ca belong to the same period or the same group on the periodic table?
The elements Ba (Barium) and Ca (Calcium) belong to the same group on the periodic table, as they both belong to Group 2 (alkaline earth metals). They do not belong to the same period, as Barium is in period 6 and Calcium is in period 4.
Why do elements in group 2 have the same properties?
Elements in group 2, like beryllium, magnesium, calcium, etc., have similar properties because they all have the same number of valence electrons (2). This results in common characteristics such as reactivity and the ability to form 2+ ions.
Do elements Ba and Ca belong to the same group on the periodic table?
Yes they do. The group goes Be, Mg, Ca, Sr, Ba, Ra
Why do the elements in the vertical columns all have the same chemical properties?
Group 1 have one valence electron. The elements in Group 2 have two. The elements in Group 17 have seven valence electrons, and Group 18 elements have eight. Because the valence electrons within a family are the same, the elements in that group have similar properties.
What elements are found in group 2 what kind of elements are they?
group 2 elements are alkaline elements.one of the element in d group is berrylium
What do elements in a group have?
Elements in a group have very similar properties and characteristics. Every element in a group has the same amount of electrons in their outer shell. For Example, all elements in Group 2 - Alkaline Earth Metals have 2 electrons in their outer shell. Elements in the same group also have very similar characteristics such as what they react with etc. For Example:Group 2 - Alkali Metals - All react vigourously in Water.Group 18(0) - Inert Gases - All are highly unreactive.
What does group 16 on the periodic table of elements have the same number of?
Group 16 on the periodic table, also known as the oxygen group, has the same number of valence electrons (6) in its outermost shell for each element within the group. This group includes elements such as oxygen, sulfur, selenium, and tellurium.
Which elements tend to possess the same number of valence electrons?
Elements in the same group or column of the periodic table tend to possess the same number of valence electrons. For example, all elements in Group 1 (such as lithium, sodium, potassium) have 1 valence electron, while elements in Group 18 (like helium, neon, argon) have 8 valence electrons except for helium, which has 2.
What is the oxidation number for group 2?
The oxidation number for group 2 elements is typically +2. These elements have 2 valence electrons that they can lose to form a 2+ cation.
