Select the atomic models that belong to the same element.
monitta

Left Panel

The trick is to look at the protons, all other things being equal. The yellow spheres are neutrons we are led to believe. All the diagrams show the same number of electrons(2), so there is no help there.

The upper left

The upper right

The Lower left

All have 2 protons and 2 electrons. <<<< Answer Read the 3 lines above.  

The center one has only 1 proton And the lower right has 3. Both of them are wrong.

Right Panel

Interpret the following equation for a chemical reaction using the coefficients given:
Liono4ka [1.6K]

Answer:  1 molecule of H_2 reacts with 1 molecule of Cl_2 to give 2 molecules of HCl.

1 mole of H_2 reacts with 1 mole of Cl_2 to give 2 moles of HCl.

Explanation:

The given balanced reaction is:

H_2(g)+Cl_2(g)\rightarrow 2HCl(g)

On the particulate level :

1 molecule of H_2 reacts with 1 molecule of Cl_2 to give 2 molecules of HCl.

On molar level:

1 mole of H_2 reacts with 1 mole of Cl_2 to give 2 moles of HCl.

Can I+ (the iodine cation) becalled a Lewis base?<br> Fullyexlplain your answer.
Alenkinab [10]

Answer: No I+ cannot be called a Lewis base.

Explanation:

According to Lewis Theory, it defines an acid as an electron-pair acceptor and a base as an electron-pair donor.

In terms of Lewis basicity, Iodide ion (anions) has the more readily available lone pair electrons for donation since iodide ion is less electronegative .

With the help of the net electronic structure one can understand the answer of the question, because we need to study the I+  ion (cation) structure.

Lewis acid is therefore any substance, that can accept a pair of nonbonding electrons. 

From the picture below I+ is most likely ready to accept electrons not to give from it 5s orbital to become stable.

slava [35]
Hey there! 

Answer: Protons 

The atom in a sample of an element must contain nuclei with the same number of protons. If the protons change in number, then the element will modify as well. 

Thank you!
