What element is represented by the following electron configuration:
Alecsey [184]
For better representation, let me rewrite the electronic configuration:

<span>1s</span>²<span>2s</span>²<span>2p</span>⁶<span>3s</span>²<span>3p</span>⁶<span>4s</span>²<span>3d</span>⁴

The exponents represent the number of electrons in the designated subshell. Thus, the total number of electrons are:
# of electrons = 2+2+6+2+6+2+4 = 24

Assuming this is in neutral state, the element with an atomic number of 24 is Chromium. Thus, the answer is Cr.

H2(g)+I2(g)→2HI(g)would not be affected by the addition of which gas?
denpristay [2]

Based on Le Chatelier's principle, the following factors will affect the chemical equilibrium

1) Temperature

2) Pressure

3) concentration

4) catalyst

The given equilibrium involves

H2(g) + I2(g) → 2HI(g)

The reactants are H2 and I2 while the product is HI. The equilibrium will be affected by changes in the concentration of H2, I2 or HI.

However, the equilibrium will not be affected by the addition of N2 since it is not involved in the reaction
