How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO 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 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.
How many valence electron does calcium have?
Calcium has 2 valence electrons, like all Group 2 elements.
How many electrons are in the valence shell of all column 1 elements?
there are 36 electrons in a valence shell. -cmoney

How many valence electrons do transition elements have?
How many valence electrons do alkaline earth metals have?
The alkali earth elements have TWO valence electrons.
What happens to the reactivity of metals from left to right across the perriodic table?
Elements become less reactive as you move from left to right across the periodic table. This is due to how many valence electrons (outer-most electrons) the element has; the less valence electrons, the more reactive the element.
How is the reactivity of elements related to valence electrons in atoms?
Valance electrons means that the element has not reached the octet configuration and is therefore reactive the reactivity depends on the no. of valance electrons the more valance electrons the more unstable the atom is and the more reactive it is.The gasses like helium neon xenon are all inert which means they have an octet configuration and have no delocalised or valance electrons.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
How is an elements most likely state related to its valence electrons?
An element's most likely state is related to its valence electrons because valence electrons determine an element's reactivity and ability to form chemical bonds. Elements with a full valence shell are stable and often found in a solid state, while elements with incomplete valence shells are more reactive and tend to form compounds in order to achieve a stable electron configuration.
How many valence electrons do elements group 17 have?
There are 7 valence electrons in elements of group-17. They are called halogens.
How many valence electrons does an element in group 4 have are they reactive?
All elements in group four have FOUR valence electrons. This is easy to remember because the group number located at the top of the periodic table of elements corresponds precisely in all cases to the experimentally observed number of valence electrons in the elements. It is also important to know that the elements in group eight (the inert gases) all have eight valence electrons, meaning that they can neither gain or lose electrons in the way of bonding with other elements, thus the maximum number of valence electrons any molecule can have is eight.
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.

Sulfur contains how many valence electrons?
Group 16 (VIB or VIA) elements have six valence electrons.
