How valence electrons are arranged in a lewis dot diagram?
choli [55]

Explanation:

In a Lewis dot diagram, the electrons are arranged so that, when full, two electrons placed beside each other are on four sides of the element symbol.

An electron is 3-dimensional, so you can start on any side on a 2D diagram.

Continue this pattern depending on how many electrons you have:

When adding an electron after the first, it is placed on the next side going either counterclockwise or clockwise. Which ever direction you choose, be consistent.

After the fourth electron, so that one electron is on each side, place a dot beside your first electron and continue the pattern.

A compound consists of 75% magnesium and 25% oxygen. Find the empirical formula.
laila [671]
<h2>Answer:</h2>

% Composition of elements:

  • Magnesium = 75%
  • Oxygen = 25%

Atomic mass of given elements:

  • Magnesium = 24 g
  • Oxygen = 16 g

Now, divide % composition by Atomic mass:

\footnotesize\implies Mg = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{75}{24}  =  \bf 3.125

\footnotesize\implies O = \dfrac{\% \:  Composition}{Atomic  \: mass} =  \dfrac{25}{16}  =  \bf 1.5625

Simplest Ratio:

\footnotesize\implies Mg  =  \dfrac{3.125}{1.5625}  = 2

\footnotesize\implies O  =  \dfrac{1.5625}{1.5625} = 1

Empirical Formula:

\footnotesize\implies \underline{ \boxed{ \red{ \bf Empirical \:  Formula = Mg_2O}}}

Determines the type of element an atom is.
VladimirAG [237]

Answer:

for number of neutrons it is mass number take away the atomic number

number of electron is the same as number of proton unless there is a charge like +2 it will have 2 less electron than the proton (atomic number ) number.

number of proton is the atomic number

Explanation:

hope it make sense:)
