Does group 2A elements lose or gain protons or electrons?
Group 2A elements tend to GAIN electrons!!
What do atoms of group 17 elments give off when they gain electrons?
Atoms of group 17 elements (halogens) give off energy in the form of light when they gain electrons. This process is known as electron capture, which releases energy as the electron moves to a lower energy level.
When elements gain three electrons to fill its valence energy level?
When these elements have five electrons on the outermost shell of electrons.
What is the expected number of valence electrons for an atom of a group 5A element?
Group 5A elements, also known as group 15 in the periodic table, typically have five valence electrons. This is because they have five electrons in their outermost energy level. These elements include nitrogen, phosphorus, arsenic, antimony, and bismuth, and their ability to gain, lose, or share these electrons influences their chemical behavior.
What is the r elationship of number of valence electrons of elements to their group in the periodic table?
Valence electrons are in the outer shell of the atom. The first column (group 1)has a +1 valence, which means that it has an extra electron it can 'lose' when bonding with other atoms. The 2nd column (group 2) has +2. The same goes for groups 3. Group 4 can gain 4 and lose 4. Group 5 can 'gain' 3 electrons, group 6 can gain 2 electrons etc.

How many electrons are required in the outer energy level for most elements to be stable?
The noble gases is the most stable group of elements. They have their outer electron energy levels full, but the number of electrons vary according to which noble gas it is. They are group 18 on the periodic table.
How many electrons are in the outer energy level of group 17 of the periodical table?
Group 17 elements, also known as the halogens, have seven electrons in their outer energy level. This allows them to easily gain one electron to achieve a stable octet configuration.
Why do elements in group 18 rarely react with other elements?
Elements in Group 18 already have an octet of electrons, which is a full outer shell of 8 electrons. An octet of electrons makes the element stable, so it does not need to react with any other elements to gain or lose electrons.
What does it mean to say some elements are reactive and form ions easily whereas others do not?
Elements form ions by either gaining or losing valence electrons. The elements that lose electron(s) and gain electron(s) acquire a positive charge and negative charge respectively. The elements that lose and gain the least electrons require less ionization energy, and are more reactive than elements that need to lose or gain more electrons. For instance, elements in group 1 of the Periodic Table need to lose one electron, and are more reactive than elements in group 2 that need to lose 2 electrons.
What is the expected number of valence electrons for an atom of a group 5A element?
Group 5A elements, also known as group 15 in the periodic table, typically have five valence electrons. This is because they have five electrons in their outermost energy level. These elements include nitrogen, phosphorus, arsenic, antimony, and bismuth, and their ability to gain, lose, or share these electrons influences their chemical behavior.
What group of elements gain two valence electrons when the atom form ionic bond?
Group 16 or the chalcogens.
How many electrons does group 7A need to become stable?
In the modern periodic table, these elements belong to group 17. These elements have s2 p5 electron configuration. Hence they need one more electron from an electron donor to fulfill its valence shell to obtain noble gas configuration.The elements in the group 7A has 7 electrons in their outermost energy level. They gain 1 electron to get the noble gas configuration. The elements in the group 7A are called halogens.
What tends to gain electrons?
Elements on the right of the periodic table but not in group 0/8 tend to gain electrons. Those in group 7 tend to gain 1 electron and those in group 6 tend to gain 2.
Elements in Group 16 of the periodic table usually?
Elements in Group 16 of the periodic table usually have six valence electrons and are nonmetals. They tend to form -2 anions when they react with other elements. These elements are known as the chalcogens and include oxygen, sulfur, and selenium.
