What else can I help you with?
What number will give you an idea on the number of valence electrons?
The number of valence electrons in an element can typically be determined by its group number in the periodic table. For main group elements, the group number corresponds to the number of valence electrons; for example, elements in Group 1 have one valence electron, while those in Group 17 have seven. Transition metals may have varying valence electrons and typically require more detailed analysis.
How many valence electrons are around the central iodine atom?
Iodine is in group 17 of the periodic table, which means it has seven valence electrons. When iodine is the central atom in a molecule, it typically retains all seven of its valence electrons unless it forms bonds with other atoms. In such cases, some of these electrons are shared with surrounding atoms, but the total number of valence electrons associated with the iodine remains seven.
What is the outer shell electrons on the periodic table?
Outer shell electrons, also known as valence electrons, are the electrons located in the outermost energy level of an atom. They play a crucial role in determining an element's chemical properties and reactivity. The number of valence electrons can often be inferred from an element's position in the periodic table, particularly within the main groups, where elements in the same group typically have the same number of valence electrons. For example, alkali metals in Group 1 have one valence electron, while halogens in Group 17 have seven.
What elements have seven valance electrons?
Elements that have seven valence electrons include the halogens in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine. These elements are highly reactive due to their tendency to gain one electron to achieve a full valence shell.
How many electrons on their outer shell does bromine have?
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
How can i look at the periodic table and tell how many valence electrons an element has?
The group of the element indicates the amount of valence electrons. For example, the alkali metals have one valence electron and is in group one whilst the halogens have seven valence electrons and are in group seven.
What does the periodic table have seven of?
valence electrons and energy sublevels

Which electron has seven valence electrons?
Any element in the halogen group will have seven valence electrons. These elements include fluorine, chlorine, bromine, iodine, and astatine.
What is the number of valence electrons of iodine?
Iodine has 7 valence electrons. It is in Group 17 of the periodic table, also known as the halogens, which have 7 valence electrons.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.

What is the number of electrons needed for stability in the groups of the periodic table?
They r noble gases which have stable valance shell and grotp no. 18
How many valence electrons dose a bromine anion contain?
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
What elements have seven valance electrons?
Elements that have seven valence electrons include the halogens in Group 17 of the periodic table, such as fluorine, chlorine, bromine, and iodine. These elements are highly reactive due to their tendency to gain one electron to achieve a full valence shell.
How many electrons on their outer shell does bromine have?
Seven , outer shell electrons or valence electrons increase as you move from left to right on the periodic table not including the transition metals which vary, they start with 1 valence in the alkali earth metals , and finish with 8 valence electrons on the noble gasses (group 18)
