Group-17 in the Periodic Table gains electron most readily. The elements in this group require only one electron to complete its octet.
What else can I help you with?
Does fluorine tend to lose electrons?
Fluorine is a nonmetal. It is located in group 17 of the periodic table. It tends to obtain an electron to form the fluoride ion.Fluorine is the element with highest electronegativity. So it does not tend to lose electrons. It is in the 17th group of the periodic table.
How many valence electrons dose a bromine anion contain?
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
How many valence electrons in arsenide ion?
Arsenide ion has 3 valence electrons. Arsenic, the element from which arsenide ion is derived, is in group 15 of the periodic table, so it has 5 valence electrons. When it forms an ion with a charge of -3, it gains 3 electrons to achieve a full octet.
What has 7 valence electrons in the periodic table?
An element with 7 valence electrons in the periodic table is nitrogen (atomic number 7). Nitrogen belongs to group 15 (or group 5A) on the periodic table, and it has 5 electrons in its outer shell and 2 electrons in the shell below, giving it a total of 7 valence electrons.
How would you find valence electrons in a periodic table?
To find the number of valence electrons of an element using the periodic table, you can look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
What gains electrons on the periodic table?
elements of group 17 (most readily) followed by group 16 and group 15
What group on the periodic table gains two electrons?
Group 16 elements.
Does group thirteen in the periodic table gain share or lose valence electrons when bonding?
Group 13 has an oxidation number of 3+ so it is more likely to lose electrons than gain them, but it is possible that it gains them
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
How many electrons are gained or lost when selenium forms an ion?
Since Selenium is a Chalcogen (meaning it's in group 6A on the Periodic Table), it gains 2 electrons to form an ion with a charge of -2.
Which group of the periodic table has 3 electrons?
all the members of 3rd A group of periodic table have 3 electrons in outermost shell they are B ,Al, Ga, Tl and In.
Does fluorine tend to lose electrons?
Fluorine is a nonmetal. It is located in group 17 of the periodic table. It tends to obtain an electron to form the fluoride ion.Fluorine is the element with highest electronegativity. So it does not tend to lose electrons. It is in the 17th group of the periodic table.
In reactions Does Strontium tend to gain or lose electrons?
In reactions, strontium tends to lose electrons because it is a metal. It is in Group 2 of the periodic table, which means it has 2 valence electrons and readily gives them up to achieve a stable configuration.
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 group of the periodic table most readily accepts electron?
Group VII A or XVII or Halogens.
How many valence electrons dose a bromine anion contain?
A bromine anion (Br-) contains 8 valence electrons. Bromine is in group 7A of the periodic table and has 7 valence electrons. When it gains an extra electron to form an anion, it now has a total of 8 valence electrons.
Which group in the periodic tables has 7 valence electrons?
group 17, halogens
