An unknown element X has the following isotopes: 58X (68.00%

Chemistry
1 answer:

5 0

The average atomic mass in amu of element X is 58.42 amu

The average atomic mass is the sum of the mass number of each of the isotopes multiplied by their respective abundances.

So;

The average atomic mass of element X is;

(58 * 0.68) + (60 * 0.26) + (0.06 * 62)

= 39.44 + 15.26 + 3.72

= 58.42 amu

The  average atomic mass in amu of X is 58.42 amu.

Two posssible lewis structures for the molecule ch2s are given. determine the formal charge on each atom in both structures
jok3333 [9.3K]

The formal charge on each atom can be known by counting up the number of valence electrons that is present on each atom.

<h3>What is Lewis structure?</h3>

The term Lewis structure is the representation of a compound using its symbols and showing the valence electrons as dots. This question is incomplete as the Lewis structures were not shown.

If it is shown, we can know the formal charge on each atom by counting up the number of valence electrons that is present on each atom.

Answer :electrostatic repulsion.

EXPLANATION

Valence shell electron pair repulsion theory, or VSEPR theory, is a model used in chemistry to predict the geometry of individual molecules from the number of electron pairs surrounding their central atoms
