What is the common oxidation number for all elements in group 17 of the periodic table?
-1.
Is Within a family on the periodic table the number of electrons on the valence level is always the same true of false?
The elements in each column of the periodic table have the same number of valence electrons. None of the other characteristics listed in the question is common to all these elements.
What does elments found in the same family on the periodic table have in common?
Elements in the same family (group) on the periodic table have the same number of valence electrons and hence they have similar properties and reactivities.
What is the difference of number of valence electrons and periodic table group number?
Valence electrons and group number for metal are same. For non-metals, valence electrons are equal to group number-10.
What happened to the number of valance electrons move from left to right on the periodic table?
the number of valence electrons increases on moving from left to right in periodic table.Group 1 has 1 valence electron and group-18 has 8 valence electrons.
What is the number of valence electrons and oxidation number of strontium?
Strontium has 2 valence electrons because it is in Group 2 of the periodic table. The oxidation number of strontium is typically +2, as it tends to lose those 2 valence electrons to achieve a stable electronic configuration.
Why is an element's oxidation number related to the group on the periodic table?
An element's oxidation number is related to the group on the periodic table because elements in the same group have similar chemical properties due to their similar electron configurations. The number of valence electrons an element has, which is determined by its group number, impacts its ability to gain or lose electrons and thus determines its common oxidation states.
What is the common oxidation number for promethium?
The valence of promethium is +3 and rarely +2.
What is the difference between oxidation number and the number of valence electrons?
The oxidation number is the charge that an atom has when forming a compound, determined by the electron gain or loss. Valence electrons are the electrons in the outermost shell of an atom, which are involved in forming chemical bonds. While the oxidation number can vary based on the compound, the number of valence electrons remains constant for elements in the same group of the periodic table.
What is the oxidation number of group 3 in periodic table?
Group 3 elements have an oxidation number of +3. This is because they have three valence electrons that are typically lost in chemical reactions, resulting in a +3 oxidation state.
What is the most important factor determining how an atom will bond?
the oxidation number, determined by its group on the periodic table.
How do you find highest oxidation number?
For most elements, their highest attainable oxidation number is equal to the number of valence electrons. Examples are the maximum oxidation numbers for: sulfur is +6, phosphorus is +5 and chlorine is +7. Fluorine is an exception which bears oxidation numbers 0, -1/2 and -1.
Coulmns on a periodic table are called?
The vertical columns of the periodic table are called groups. The horizontal rows of the periodic table are called periods. The number of electron shells an atom has corresponds to the number period of the periodic table it is located in. The oxidation number or number of valence electrons an atom is depicted by the group it is in. For example: Calcium (Ca) has an oxidation number of +2 and has 2 valence electrons( outermost electrons) which means it belongs to group 2 of the periodic table called the "alkali earth metals".
What do atoms of elements in the same group of the periodic have in common?
number of valence electrons
How can the periodic table help you determine the number of valence?
The group number of an element on the periodic table corresponds to the number of valence electrons it has. For main group elements, the group number indicates the number of valence electrons. Transition metals may have varying valence electrons based on their oxidation states.
What is the common oxidation number for all elements in group 17 of the periodic table?
-1.
What determines the most likely oxidation state of an element?
the number of electrons the element needs to lose or gain to have a full valence shell
