Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
The number of valence electrons in group 2 elements is?
Group 2 elements have 2 valence electrons. This is because they are located in group 2 of the periodic table, which corresponds to the number of valence electrons in the group. Examples of group 2 elements include beryllium, magnesium, calcium, strontium, barium, and radium.
In group 2 on the periodic table are they positive ions when they bond with other elements?
Elements from the group 2 of the periodic table form cations.
The atomic charges of each group?
There's no charge within the atom of each group since there is a same number of electrons (negatively charged) and protons ( positively charged). The charge does not change unless after ionic bonding. The atomic charge changes depending on the reaction.
How is helium similar to group two elements?
Helium is similar to group 2 elements because it is a noble gas, meaning it has a full outer electron shell which makes it stable and unreactive. Group 2 elements also have stable electron configurations with filled s orbitals in their outermost energy level.
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 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.
Which group is more reactive on the periodic table group 1 or 2?
Group 1 elements are more reactive than that of group 2 elements.
Group a elements on the periodic table?
2 elements
What is the oxidation number for group 2 elements?
Hydrogen has -1 and +1 oxidation numbers. Other elements have +1 only
The number of valence electrons in group 2 elements is?
Group 2 elements have 2 valence electrons. This is because they are located in group 2 of the periodic table, which corresponds to the number of valence electrons in the group. Examples of group 2 elements include beryllium, magnesium, calcium, strontium, barium, and radium.
What is the number of valence electrons for group 2 elements?
Group 2 metals have 2 valence electrons. In fact, the number of valence electrons of elements can be deduced from the group number (e.g. group VII elements have 7 valence electrons).
What groups of elements does the s-block contian?
Group 1 and group 2 elements are called s-block elements
What are in the main group of elements?
Groups 1, 2, and 13 - 18 are the main group elements, also called the representative elements.
Are group 3A elements known as alkaline earth metals?
No,but group 2 are alkaline earth elements
Elements that have a single oxidation number?
Elements that have a single oxidation number include group 1 elements (e.g. sodium, potassium) which have an oxidation number of +1, and group 2 elements (e.g. magnesium, calcium) which have an oxidation number of +2.
