<span>Picture showing seven layers of rocks of different colors labeled A, B, C, D, E, F, and G from top to bottom;
A and B are parallel horizontal layers at the top of the diagram;
C, D, E, F, and G are slanted layers with C closest to the surface and G at the bottom.

The valence electrons of an atom of which element would feel a smaller effective nuclear charge than the valence electrons of a
d1i1m1o1n [39]
Any element with to the right on the periodic table, or down below Ca on the periodic table, will feel a smaller effective nuclear charge. Elements to the right of Ca have more valence electrons to 'share' the pull of the protons in the nucleus. Elements below Ca have additional, filled shells of electrons, shielding the valence electrons from the nucleus.

How many hydrogen atom are present in 1.53 g of water
svp [43]

Answer:

=1.02x10^{23} atoms\ H

Explanation:

Hello,

In this case, for water, whose molar mass is 18 g/mol, we can find two moles of hydrogen in one mole of water, therefore, for us compute the atoms, we should also use the Avogadro's number as shown below:

=1.53gH_2O*\frac{1molH_2O}{18gH_2O}*\frac{2molH}{1molH_2O} *\frac{6.022x10^{23}atoms\ H}{1molH} \\\\=1.02x10^{23} atoms\ H

Regards.
