Ruthenium is a chemical element with the symbol Ru and atomic number 44. The electron configuration of Ru is 5s14d^{7}.

<h3>How to write an electronic configuration?</h3>
  • Find the supplied element's atomic number on the periodic table and identify it.
  • The energy level and kind of orbital should be listed first, followed by the number of electrons in the orbital in superscript.
  • The Aufbau principle's diagonal rule for electron filling order in the various subshells is the simplest way to express the electronic configuration of any element.
  • The Aufbau rule, the Pauli-exclusion rule, and Hund's Rule are the three rules that must be followed when expressing the electron configuration in the orbital box diagram.

Ruthenium exists a chemical element with the symbol Ru and atomic number 44. The electron configuration of Ru is 5s14d^{7}.

PLEASE ANSWER ASAP- In the solid state, how does Water compare to Neon and Argon? Why do you think they act differently?
alekssr [168]
Neon and Argon are known as the noble gases. This means that there inert and don’t typically react. The noble gases have full outer shells and therefore satisfy the octet rule. Hydrogen, on the other hand, must lose an electron to become stable. That is why it reacts.

Calculate the density of the items below. (D = M/V)<br> 1) M = 15g V = 5.0ml *
grin007 [14]

Answer:

<h3>The answer is 3.0 g/mL</h3>

Explanation:

The density of a substance can be found by using the formula

density =  \frac{mass}{volume} \\

From the question

mass = 15 g

volume = 5 mL

We have

density =  \frac{15}{5}  \\

We have the final answer as

<h3>3.0 g/mL</h3>

Hope this helps you
