How to draw an.electron dot diagram. 1 write the chemical aymbo of the atom.2. Determine the number of valence electron the atom

has.3. Place first two dot on the right side of the symbol.4. Place the remaining dots around the symbol( on the bottom.the left side,and on top) 5. There should not be any more than two dots on either side .top.or bottom, and no electron should be left over. Please help its my first time doing these .

Basically, an electron dot diagram is just a diagram showing the number of valence electrons a certain atom has (valence electrons are electrons in the outer-most electron level of an atom). The 5 steps they give you just tell you the order of where to put each dot.  The picture I attached gives a better representation.

The number around the symbol shows the order of where you would put the dot.  The 1 and the 2 on the top show that the first two dots go there, and the 3, 4, and 5 go around the rest of the sides.  When it gets to 6, 7, and 8, the numbers go back around to fill  in each side twice.

atoms of silver is approximately 820 g.

Explanation:

In order to determine the mass of a given number of atoms of an element, identify the equalities between moles of the element and atoms of the element, and between moles of the element and its molar mass.

A student has two unopened 33 CL cans containing carbonated water. Can A has been stored in the garage 32 degrees and can B has
IgorC [24]

Answer:

A. Can A will make a louder and stronger fizz than can B.  

Explanation:

The solubility of a gas in a liquid decreases as the temperature increases, so the warmer can will have more undissolved carbon dioxide.

The warmer can will be under greater pressure, so it will make a louder and stronger fizz.

A nuclear waste site. cesium-137 is a particularly dangerous by-product of nuclear reactors. it has a half-life of 30 years. it
hram777 [196]
The mass decay rate is of the form
m(t) = m_{0} e^{-kt}
where
m₀ = 3000 g,the initial mass
k = the decay constant
t = time, years.

Because the half-life is 30 years, therefore
e^{-30k} =  \frac{1}{2} \\\ -30k = ln(0.5) \\ k =  \frac{ln(0.5)}{-30} =0.0231

After 60 years, the mass remaining is
m = 3000 e^{-0.0231*60} = 750 \, g

Answer: 750 g

Which of the following is true of solids?
Over [174]
<span>Answer: B. Ionic solids have higher melting points than molecular solids.
</span>
This is because the rest are false, as solids are able to melt, and do have melting points. Also, not all solids have the same melting points.
