Why do elements in group 2 have an oxidation number of -1?
In group 2 elements like alkaline earth metals, the common oxidation number is +2, not -1. This is because these elements tend to lose 2 electrons to achieve a stable octet configuration and form 2+ cations.
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.
Oxidation number for first 20 elements?
The oxidation numbers for the first 20 elements in the periodic table are typically as follows: Group 1 elements: +1; Group 2 elements: +2; Group 13 elements: +3; Group 14 elements: +4 or -4; Group 15 elements: -3; Group 16 elements: -2; Group 17 elements: -1; Group 18 elements: 0. Keep in mind that oxidation numbers can vary in different compounds and contexts.
What is a common name for the elements that make up group 18?
The elements that make up Group 18 on the Periodic Table are caleed noble (or inert) gases.
What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only

What what elements most common oxidation state is 2?
Elements in group 2 mostly takes the oxidation number +II.
Why do elements in group 2 have an oxidation number of -1?
In group 2 elements like alkaline earth metals, the common oxidation number is +2, not -1. This is because these elements tend to lose 2 electrons to achieve a stable octet configuration and form 2+ cations.
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
Which choice represents a group of elements with common characteristics?
Copper, gold, and silver are the choices that represent a group of elements with common characteristics. All of these elements are metals.
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.
What is the charge for a group six ion?
The most common charge (or valency) is -2. But there are compounds formed by elements of group VIA with valency from -2 to +6
What is a common oxidation number that is -2?
Generally for group 16 elements, like oxygen, sulphur, selenium.
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.
