Chapter 3, Problem 3.45E

ELEMENT X HAS AN ATOMIC NUMBER OF 9 How many atomic orbitabls does atom X have? How many shells do the electrons of atom X occupy? What is the electron configuration of the valence electrons of atom X? How many valence electrons does your element X have? How many orbitals are unpaired?

Why do atoms of elements form chemical bonds? A. To achieve a atable configuration. B. To attach to other atoms. C. To release energy. D. All of the above

Compare the configurations below with two electrons located in p orbitals. Which would be the most stable (have the lowest energy)? Which would be the least stable? Explain your answers.</o:p>   </v:imagedata> </v:shape></o:p>

Rank the following in order of increasingradius:(a) O²⁻, F⁻, Na⁺(b) S²⁻, P³⁻, Cl⁻

differentiate sigma orbital and pi orbital. make an illustration to support explanation.

Compared to their neutral atom counterparts, ions will have smaller or larger atomic radii due to their losing or gaining electrons. According to Jensen (2010), Linus Pauling assigned the radius of the oxygen anion (O“) at 140 pm (larger than the neutral atom, 66 pm). On the other hand, the magnesium atom loses 95 ppm from its 160 ppm radius when it loses two valence electrons, forming the magnesium ion.  Determine the value of constant B wen constant n is approcimately 8. Unit is in N-m9

Use trends within the periodic table and indicate which member of each of the following pairs gives up one electron more easily: a.Li or K b.C or Sn c.Mg or S d.Li or N
