How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
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).
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.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
How many valence are in chlourine?
A total of 7 valence electrons. If I remember correctly, the number of valence electrons of all group A elements are designated by their group number. Chlorine is in group VIIA, hence 7 valence electrons.
Which group of elements 7 valence electrons?
The groups of electrons with 7 valence electrons are groups 7 and 17 on the periodic table.
What is the general valence shell configuration for the elements in group 7A?
Valence electron configuration in group 7A (halogens): ns2, np5 in which n=2, 3, 4, 5, ... etc. Starting with fluorine, F, electron configuration: (1s2), 2s2 2p5 (non valence electrons in () brackets)
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
How many valence electrons do halogens gave?
Halides have 7 valence electrons, but the halide ion, haven gained an electron has 8 valence electrons
What p block has 7 valence electrons?
The group 17 of p block has 7 valent electrons. These elements are called halogens.
What group of elements has seven valence electrons?
The name of the family is the Halogen family.
How many valance electrons does halogen have?
Halogens are group 17 elements. They have 7 valence electrons.
