As - 8 dots and 3- charge, Se - 8 dots and 2- charge, Br - 8 dots and 1-, K - zero dots and +1 charge, Ca - zero dots and +2 charge, Ga - zero dots and +3 charge.

<h3>In the periodic table of the elements, what is its Lewis symbol?</h3>

The valence electrons of each element are represented by dots that surround their chemical symbol in a Lewis dot symbol. The Lewis dot symbol's dots correspond to the valence electrons, which correspond to the final digit of the element's group number as in periodic table.

<h3>What's an example of a Lewis symbol?</h3>

Two chlorine atoms, for instance, share one pair of electrons when they combine to form a chlorine molecule. According to the Lewis structure, each Cl atom contains one shared pair of electrons and pairs of electrons that aren't employed in bonds (known as lone pairs) (written between the atoms).

First, it combines with carbon dioxide in the soil to form a weak acid called carbonic acid. ... Carbonic acid slowly dissolves away minerals in rock, especially the carbonate minerals that make up limestone and marble. The weak acid decomposes the insoluble rock into watersoluble products that move into the groundwater.

Write the beta decay equation for the following isotope: 91 38 Sr? Please write out steps
babymother [125]

Answer:

\rm _{38}^{91}Sr \longrightarrow \,  _{-1}^{0}e + \,  _{39}^{91}Y

Explanation:

The unbalanced nuclear equation is

\rm _{38}^{91}Sr \longrightarrow \,  _{-1}^{0}e \, + \, ?

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

\rm _{38}^{91}Se} \longrightarrow \,  _{-1}^{0}e \, + \,  _{Z}^{A}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

98 =  0 + A, so A =  98 -  0 = 98, and

38 = -1 + Z, so Z  = 38 + 1 = 39

Then, your nuclear equation becomes

\rm _{38}^{91}Sr \longrightarrow \,  _{-1}^{0}e + \,  _{39}^{91}X

Element 39 is yttrium, so the balanced nuclear equation is

\rm _{38}^{91}Sr \longrightarrow \,  _{-1}^{0}e + \,  _{39}^{91}Y
