Why do elements in group 2 have an oxidation number of plus 2?
Elements in group 2 have an oxidation number of +2 because they readily lose two electrons to achieve a full outer shell, which is the most stable electron configuration. This results in a +2 oxidation state as they become positively charged cations.
What is oxidation state of mg plus plus?
The oxidation state of Mg2+ is +2. Magnesium typically forms cations with a +2 charge by losing 2 electrons.
What is lithium's charge?
A lithium ion has a charge of +1
Ions with a 2 plus charge?
two elements with ions with a 2 plus charge are Sulfurand Oxygen
How many electrons occur in the valence level of Group 7A and 7B elements. Why are they different?
Group 7A elements have 7 electrons in their valence level, while Group 7B elements have 17 electrons in their valence level. This difference occurs because elements in Group 7A have 7 valence electrons, while elements in Group 7B have 7 valence electrons plus the 10 additional electrons in the d sublevel which contributes to a total of 17 valence electrons.
Why do elements in group 2 have an oxidation number of plus 2?
Elements in group 2 have an oxidation number of +2 because they readily lose two electrons to achieve a full outer shell, which is the most stable electron configuration. This results in a +2 oxidation state as they become positively charged cations.
What group of the periodic table has a 2 plus charge and is reactive?
Group 2 elements of the periodic table have a 2+ charge and are reactive. These elements include beryllium, magnesium, calcium, strontium, barium, and radium. They readily form 2+ cations by losing two electrons in chemical reactions.
What is oxidation state of mg plus plus?
The oxidation state of Mg2+ is +2. Magnesium typically forms cations with a +2 charge by losing 2 electrons.
Ions with a plus charge are called?
Cations.
What is lithium's charge?
A lithium ion has a charge of +1

What species is reduced in the reaction Fe plus AgNO3 FeNO3 3 plus Ag?
Iron reduce silver cations.
AgNO3 plus NaCl ----- AgCl plus NaNO3?
The reaction between silver nitrate (AgNO3) and sodium chloride (NaCl) forms silver chloride (AgCl) and sodium nitrate (NaNO3). This is a double displacement reaction where the cations and anions switch partners. Silver chloride is a white precipitate that forms in this reaction.
Has oxidation numbers of plus 1 and -1?
Elements with oxidation numbers of +1 include elements in Group 1 of the periodic table, like hydrogen and sodium. Elements with oxidation numbers of -1 include elements in Group 17, like fluorine and chlorine.
What group of elements tends to form plus 2 charge?
The Group 2 elements, or the Alkali Earth metals, tend to form +2 charges when they become ions. This is because Group 2 metals have 2 valence electrons and it is easier to lose 2 electrons than it is to gain 6 electrons to form a full outer shell.
What is Silver oxide plus hydrochloride acid?
When silver oxide reacts with hydrochloric acid, it forms silver chloride and water. This is a double displacement reaction where the cations and anions switch partners. Silver chloride is a white precipitate that is insoluble in water.
