One minus two equals negative one and three minus five equals negative two
Answer:
The element with electron configuration 1s² 2s² 2p⁶ will most likely not react with an element having seven Valence electrons.
The electron configuration of the element in discuss is 1s² 2s² 2p⁶.
The element has enough electrons to fill it's energy level, n = 2 shell.
In essence, the element in discuss is unreactive as it has attained it's octet configuration and as such is neither in need of an electron nor ready to donate an electron.
As such, although an atom having seven Valence electrons is highly electronegative and as such is an electron attractor, the element with the full octet configuration does not react with it.
This unreactive nature of noble gases is attributed to the full octet configuration of noble gases.
P.S: The electron configuration above is the electron configuration of Neon, Ne.
Answer:
Double Displacement reaction
Explanation:
BaCl2 + Na2SO4 → 2NaCl + BaSO4
Double displacement reaction occurs when the cations and anions of the two reacting compound interchange, forming a new products. From the equation given above, Na^+ switch place with Ba^2 + and likewise Cl^- with (SO4) ^2- to form NaCl and BaSO4.
