Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
The elements in groups 1A and 2A have valence electrons in s-orbitals, while the elements in groups 3A-8A have valence electrons in p-orbitals.
Valence electrons are responsible for chemical boding.
The electron configurations of all the elements in a group have the same number of valence electrons. Valence electrons are the electrons found in the outermost shell of an element.
The electron configurations of the elements in each main group are regular and consistent:the elements in each group have the same number of valence electrons.
Yes. In terms of electron configuration and the number of valence electrons.
How many valence electrons do transition elements have?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other 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).
The most stable number of valence electrons is 2 for hydrogen and helium, which have only one electron shell in the shell model for atomic electron configurations, and 8 for all other elements.
Elements in the same group have the same number of valence electrons.
All elements in the same group have the same number of valence electrons.
Halogen family members, or elements in group 17, have 7 valence electrons.
That depends on the element in question. Atoms can have anywhere from 1 to 8 valence electrons. For the main group elements, Groups 1,2,13-18, the number of valence electrons are the number in the one's place in their group number, as follows: Group 1 Elements: 1 valence electron Group 2 Elements: 2 valence electrons Group 13 Elements: 3 valence electrons Group 14 Elements: 4 valence electrons Group 15 Elements: 5 valence electrons Group 16 Elements: 6 valence electrons Group 17 Elements: 7 valence electrons Group 18 Elements: 8 valence electrons The transition metals, Groups 3 - 12, are more complicated because they are adding d electrons, some of which behave like valence electrons, and many transition metals can have different numbers of valence electrons. For example manganese can have anywhere from 2 to 7 valence electrons.
The elements in groups 1A and 2A have valence electrons in s-orbitals, while the elements in groups 3A-8A have valence electrons in p-orbitals.
