Which one of the following statements about s orbitals is incorrect ?

Rutherford bombarded gold foil with alpha (a) particles and found that a small percentage of the particles were deflected. Which

Alex73 [517]

Answer:

The presence of neutrons

Explanation:

Based on gold foil experiments, Rutherford proposed a atomic model known as Rutherford'd model or nuclear model or planetary model of the atom.

As per this model, most of the mass of the atom is concentrated in the center of the atom known as nucleus.

Electrons revolve around it same as planet revolve around sun.

Since, neutrons had not been discovered at the time of Rutherford'd model, therefore, as per the Rutherford'd model, nucleus is only made of protons.

Therefore, the correct option is option B

How many atoms of N are in 0.82 g of NaNO3? ( molar conversion)

VMariaS [17]

The number of atoms N = 5.8 x 10²¹

<h3>Further explanation</h3>

A mole is a unit of many particles (atoms, molecules, ions) where 1 mole is the number of particles contained in a substance that is the same amount as many atoms in 12 gr C-12

1 mole = 6.02.10²³ particles

mass of N in 0.82 g of NaNO₃ (MW NaNO₃: 85 g/mol) :

$\tt mass~N=\dfrac{Ar~N}{MW~NaNO_3}\times mass~NaNO_3\\\\mass~N=\dfrac{14}{85}\times 0.82\\\\mass~N=0.135~g$
