Answer:
B) They will react because X and Y can share two pairs of electrons to become stable
Explanation:
The electron configurations of two elements x and y are given :
X: 1s2 2s2 2p6
Y: 1s2 2s2 2p6 3s2 3p6
The statement that is true for both the elements is that, they both will react as they both can share two pairs of electrons to become stable.
To become stable the outermost shell or p orbital should have 8 electrons, so element X can gain 2 atoms to become stable.
Element Y can also react as it can also share two atoms to fulfill its 3p orbital and will stable.
Hence, the correct option is "B".
The answer would be B, an electron because the proton is positive, neutron is neutral, and the nucleus is the center of the atom.
It's the rows. They are periods. (1,2,3,4,5,6,7 - the ones without the letters).
Talk to it about it's emotions and if it breaks down crying immediately then it is unstable.
