What happens if the elements have different protons and electrons?
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
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.
Does group 13 elements lose or gain valence electrons?
Group 13 elements tend to lose three valence electrons to achieve a full outer shell configuration. They typically form 3+ ions by losing these three electrons.
What group of elements on the periodic table gain electrons when bonding?
in group 15 of the periodic table, how many electrons does group 15 gain?
What elements gain electrons when they bond?
Nonmetals gain electrons in chemical reactions.
How many electrons does group 6A need to gain to become a noble gas?
They should gain 2 electrons to attain noble gas electronic configuration. (it doesn't become a noble gas as the number of protons are not same)
What happens if the elements have different protons and electrons?
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
What group of elements gain two valence electrons when the atom form ionic bond?
Group 16 or the chalcogens.
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.
Compared with Group 2A elements Group 6A elements have?
Group 6A elements have a higher electronegativity and a greater tendency to gain electrons to achieve a stable octet configuration. In contrast, Group 2A elements have a lower electronegativity and typically lose electrons to form cations.
Are atoms of group 16 elements more likely to gain or lose electrons?
Atoms of group 16 elements are more likely to gain electrons because they have 6 valence electrons and need 2 more to achieve a stable octet configuration, which is typically done by gaining electrons rather than losing them.
Determine the typical charge for an atom?
An atom is always neutrally charged, with equal numbers of protons and electrons. As soon as elements lose or gain electrons, they become ions.
Do atoms lose protons but seldom lose or gain electrons?
Atoms typically do not lose protons because that would change the identity of the element. Instead, atoms can lose or gain electrons to form ions with a different charge. Protons are not generally lost by atoms in chemical reactions.
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.
When Group 7A elements in a periodic table form ions do they lose or gain protons?
The elements in group 7A or 17, gain one electron during ionic bonding, or share one electron when undergoing covalent bonding.
Does group 13 elements lose or gain valence electrons?
Group 13 elements tend to lose three valence electrons to achieve a full outer shell configuration. They typically form 3+ ions by losing these three electrons.
