<u>Answer:</u> The correct answer is 4-7.

<u>Explanation:</u>

A non-metal is defined as the element which gains electron to attain stable electronic configuration and to attain a negative ion which is anion.

X+ne^-\rightarrow X^{n-}

Non-metals are the elements which belong to Group 14 to Group 17.

The valence electronic configuration of the elements:

  • Belonging to Group 14 = ns^2np^2

Number of valence electrons = 4

  • Belonging to Group 16= ns^2np^3

Number of valence electrons = 5

  • Belonging to Group 16 = ns^2np^4

Number of valence electrons = 6

  • Belonging to Group 17 = ns^2np^5

Number of valence electrons = 7

Hence, the correct answer is 4-7.

The radioactive atom 61/27 co emits a beta particle. write an equation showing the decay
pickupchik [31]

Answer:

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}

Explanation:

The unbalanced nuclear equation is

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, ?

Let's write the question mark as a nuclear symbol.

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \,  _{Z}^{A}\text{X}

The main point to remember in balancing nuclear equations is that the sums of the superscripts and the subscripts must be the same on each side of the equation.  

Then

60 = 0 + A, so A = 60 - 0 = 60, and

27 = -1 + Z, so Z  = 27 + 1 = 28

Your nuclear equation becomes

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{X}

Element 28 is nickel, so the balanced nuclear equation is

\rm _{27}^{60}\text{Co} \longrightarrow \,  _{-1}^{0}\text{e} + \, _{28}^{60}\text{Ni}
