Most likely the second one (sand letting water run through it) because if you are trying to determine how what moves through soil You would want the one the one that can do that:)

Explain where the weight of an atom is found what is responsible for that weight and why
padilas [110]

Answer:

The majority of the weight in an atom is found in the nucleus.

Explanation:

The protons and neutrons that make up the nucleus of the atom may take up a tiny amount of space in comparison to the rest of the atom, but they are far more dense than the electrons that orbit the nucleus.

Effective nuclear charge, Zeff, is defined as:
Alborosie

Answer:

The effective nuclear charge for a valence electron in oxygen atom: Z_{eff} = 4.55

Explanation:

Effective nuclear charge  [Z_{eff}] is the net nuclear charge experienced by the electron in a given atom. It is always less than the actual charge of the nucleus [Z], due to shielding by electrons in the inner shells.

<em>It is equal to the difference between the actual nuclear charge or the atomic number (Z) and the shielding constant (s).  </em>

\Rightarrow Z_{eff} = Z - s

<u>For an oxygen atom</u>-

Electron configuration: (1s²) (2s² 2p⁴)

<em>The atomic number (actual nuclear charge): </em>Z = 8

The shielding constant (s) for a valence electron can be calculated by using the Slater's rules:

⇒ s = 5 × 0.35 + 2 × 0.85 = 1.75 + 1.7 = 3.45

<u><em>Therefore, the effective nuclear charge for a valence electron in oxygen atom is:</em></u>

Z_{eff} = Z - s = 8 - 3.45 = 4.55

<u>Therefore, the effective nuclear charge for a valence electron in oxygen atom:</u> Z_{eff} = 4.55
