OXYGEN because it has only one oxidation state of -2, all the other elements in the group have multiple oxidation states.
No elements in group 10 is most likely to gain an electron.
Maybe,beryllium
oxygen
Chlorine
NO
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
The alkaline earth group has two valence electrons.
The periodic table also has a special name for its vertical columns. Each column is called a group. The elements in each group have the same number of electrons in the outer orbital. Those outer electrons are also called valence electrons.
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.
Group 1 or group 2 elements with group 16 or group 17 elements. In general, if the electronegativity difference between the two atoms is more than 1.7 in Pauling's scale, then the two atoms form ionic bond.
The atoms of the elements in Group 13 (IIIA), the boron group, have three valence electrons, all of which are unpaired. The atoms of the elements in Group 15 (VA), the nitrogen group, have five valence electrons, three of which are unpaired.
Atoms of the elements in a group have the same number of electrons in their outer energy shells. This gives the elements similar Chemical Propetries.
System overload (explodes) (boom) (smoke) (etc.)
Such atoms belong to a group in the periodic table of elements.
Atoms of elements in group (column 2 of the periodic table) have 2 electrons in their outer shell. They have a low electronegativity, which means the electrons are not strongly attracted to the protons in the nucleus when compared to the electrons in atoms of column 6 or 7. For this reason, group 2 elements easily form +2 ion when in the presence of group 6 or7 elements.
number of valence electrons
Elements in group 1 have a lower number of electrons with respect to the other elements in the same period.
If I recall correctly, it's because they don't have any electrons in their atoms. Atoms react in order to get a full set of 8 electrons, and the less electrons an atom has, the more likely they are to react.
System overload (explodes) (boom) (smoke) (etc.)
It is group 16, also known as the chalcogens
The atoms of the elements in the same group have the same number of valence electrons. This means that they react with other elements in a similar way. For example group 1. All the atoms in group 1 react with water and oxygen, so they have to be kept in paraffin-oil. Another example is group 18. They don't react with anything. The atoms of the same row have the same electron shells.
Groups, in the periodic table of elements, are elements that all have the same number of valance electrons, which in turn tells us a lot about the kinds of chemical reactions that these elements will or will not undergo.
