Question

When neutral, Ecorium has 126 protons and 126 electrons. Given that it has 6valence electrons, what is the effective nuclear charge felt by these outer electrons?

Answer 1

`+6`

Step-by-step explanation:

Here, we want to calculate the effective neutral charge

From the question, there are 126 electrons

Since there are 6 valence electrons, the number of electrons residing outside the valence electrons is 120

The effective nuclear charge is the difference between the number of protons and the number of electrons outside the valence shell

Mathematically, we have it that:

`Nuclear\text{ charge = 126 - 120 = +6}`
