Ir = [Xe] 4f14 5d7 6s2
<span>Rn = [Xe] 4f14 5d10 6s2 6p6 </span>
<span>Fe = [Ar] 3d6 4s2 </span>
<span>Pa = [Rn] 5f2 6d1 7s2 </span>
<span>Y = [Kr] 4d1 5s2 </span>
<span>Re = [Xe] 4f14 5d5 6s2 </span>
<span>So only Rhenium (Re) has an electronic configuration where the d orbital has 5 electrons in it.</span>
Answer:
stratosphere - The stratosphere is a layer of Earth's atmosphere. It is the second layer of the atmosphere as you go upward.
mesosphere - The mesosphere is a layer of Earth's atmosphere. The mesosphere is directly above the stratosphere and below the thermosphere
thermosphere - The thermosphere is a layer of Earth's atmosphere. The thermosphere is directly above the mesosphere and below the exosphere.
Answer:
C is Correct
Explanation:
Protons and Neutrons make up the Nucleus while Electrons surround the nucleus in circular orbits with continuous rotation.
A secondary alcohol has a hydroxyl group bonded to a disubstituted carbon bonded to one alkyl group carbon bonded to two alkyl groups carbon bonded to three alkyl groups aromatic carbon.
An alkene in which the doubly bonded carbons are bonded to a total of two carbon atoms, its a distributed alkene.
Answer:
a new substance is formed, if heat is formed, color change, the evolution of gas, and bubbles or fizzing
