What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
What group in the periodic table gains electrons most readily and why?
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
What element gain 5 electrons?
Firstly I would like to correct you on your grammar. The question should in fact ask 'which' element gains 5 electrons. The question is also flawed form the start because more than one element gains 5 electrons. All elements in group 3 of the periodic table have 5 spaces in the outer shell. All elements want to feel complete, and the maximum amount of elements on the outer shell is 8. Therefore 3 + 5 = 8. So hey presto this is my answer to you. ~K :)
What are the Every element in group one has one electron in its outer shell Every element in group two has two electrons in its outer shell?
Both statements are true:Every element in group I has one electron in its outer shell andEvery element in group II has two electrons in its outer shell
Based on their placement on the periodic table what about ion formation is correct There is more than one correct statement?
A Group 6A element gains two electrons A Group 2A element loses two electrons A Group 3A element loses three electrons A Group 3A element loses three electrons group 1a element loses one electron group 7a gains one electron
As you move down a group elements have how many electrons shells than those above them?
going down a group, each element gains 1 shell (energy levels)
What group on the periodic table gains two electrons?
Group 16 elements.
What is the expected number of valence electrons for a group 3 A element?
The expected number of valence electrons for a group 3 A element is 5 number of valence electrons.
What element has 2 electron shells and 4 valence electrons?
Two electrons imply that the element is in the second period. The 4 valence electrons says that it is located in group 4A (or group 14 in modern notation). Hence, this element is carbon.The element has 2 electron shells means the element is in the 2nd group. This element is carbon. It has 4 valence electrons.
What gains electrons on the periodic table?
elements of group 17 (most readily) followed by group 16 and group 15
In orde rto be like noble gas an element can change which subatomic particle?
An element can either gain or lose electrons to achieve a noble gas electron configuration. Such an electron configuration gives an atom of an element a full outer shell, thereby making that element's ion nonreactive. Metals tend to lose electrons, and become cations, whereas nonmetals tend to gain electrons, and become anions. The amount of electrons an element gains of loses is based on the group/family the element is found in on the Periodic Table.
What group in the periodic table gains electrons most readily and why?
Group-17 in the periodic table gains electron most readily. The elements in this group require only one electron to complete its octet.

How many valence electrons in any element in a group?
Same as the group number.
Number of valence electrons found in an atom of a group A element is equal to what?
group #
