Sulfur will gain 2 electrons
2 electrons as barium has 56 electrons so it will lose two electrons to reach the electronic structure of the nearest noble gas which is xenon 54 electrons
It must give away two valence electrons.
Two electrons.
Two, to raise the outer shell total to eight electrons, like that of the next heavier noble gas.
As it is in group six and therefore nearer to the Noble Gases it gains.
Sulfur atoms will gain two electrons in order to achieve a noble gas electron configuration. A sulfide ion has the formula S2-.
It must lose two electrons.
A Sulfur atom has initially 6 electrons in its outer shell. To have a complete octet, meaning 8 electrons in the outer shell, it should gain 2 electrons, to form an S2- ion.
2 electrons as barium has 56 electrons so it will lose two electrons to reach the electronic structure of the nearest noble gas which is xenon 54 electrons
Phosphorus has to gain a total of 3 electrons to achieve a noble gas configuration. You can find this for any non-metal because the last digit of its group number is the number of valence electrons it has. For example Phosphorus has 5 and Sulfur has 6. In order to achieve a noble gas electron configuration, you must have 8 valence electrons, so phosphorus must gain 3.
It must give away two valence electrons.
loses 2 electrons to achieve a noble gas configuration
Nonmetals tend to gain electrons to form ions so as to obtain noble gas configuration.
It must gain one electron to achieve a noble gas electronic structure, just like other halogens.
Oxygen should gain 2 electrons to achieve noble gas configuration
Sulfur must to have an electrons octet.
Calcium should lose 2 valence electrons and attain the noble gas configuration of argon with 18 elements.
