Not sure if I understand your question correctly, but some elements are more electronegative than others, so they draw in electrons better than others. For example, in NaCl, chlorine (Cl) is much more electronegative than sodium (Na) so it simply takes the sodium's extra valence electron.
What else can I help you with?
Do only outer shells gain or lose electrons with other atoms?
Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched. Yes. Only the valence shell will interact with other atoms. This is how different elements are different from eachother. The electrons under the valence shell are never touched.
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.
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).
What shows an element's combining ability?
An element's combining ability is determined by its valence electrons, which are the electrons in the outermost energy level. Elements with few valence electrons tend to lose or share electrons in chemical reactions, while elements with many valence electrons tend to gain or share electrons. This behavior allows elements to form chemical bonds and combine with other elements to achieve a more stable electron configuration.
The Halogen family elements have how many valence electrons?
Halogen family members, or elements in group 17, have 7 valence electrons.
What do the chemical reactions of elements depend on?
Valence electrons.
Do only outer shells gain or lose electrons with other atoms?

How are the elements within row different?
They have different numbers of valence electrons.
What is the different about the valence electrons for all elements in a group?
Valence electrons for elements in the same group are the same because they are located in the outermost energy level of an atom. This common number of valence electrons is what gives elements within a group similar chemical properties.
What are the uses of valence electrons?
Valence electrons are important for the chemical reactions.
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 electrons do transitions elements have?
How many valence electrons do transition elements have?
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).
What describes a valence electron?
Valence electrons are the electrons involved in chemical reactions.
Why do the elements belonging to a particular group exhibit similar chemical behavior?
Elements in the same group have the same number of valence electrons, which dictates their chemical behavior. Valence electrons are responsible for the way atoms interact with each other in chemical reactions. This similarity in valence electron configuration leads to similar chemical reactivity among group members.
How many electrons does an atom need to a outer energy level?
There are different numbers of valence electrons in different elements.
Which is the correct number of valence electrons in the element Gallium (Ga)?
Gallium (Ga) has three valence electrons. It is in group 13 of the periodic table, which indicates that elements in this group typically have three electrons in their outermost shell. These valence electrons are involved in chemical bonding and reactions.
