Tasha and boris, expectant parents, wonder about the endless possibility of traits their unborn son might inherit from them (e.g., tasha’s red hair and allergies; boris’s tall frame and poor eyesight). as a genetics expert, you tell them that after cell division, the egg or sperm contains 23 chromosomes; thus, a male or female can produce different combinations of his or her chromosomes.

What element has the same number of orbits as Hydrogen? Why? Do they have similar properties, why?

Helium

Explanation:

Helium has the same number of orbitals as hydrogen because they belong to the same period on the periodic table.

Periods are the horizontal arrangement of elements. Elements in the same period are known to have the same number of electronic shell or orbitals.

In period 1 where we have just Hydrogen and Helium, the number of orbitals is 1.

For properties of a specie, elements in the same group which are the vertical arrangement of elements have the same properties. Since both Hydrogen and helium are in different groups, their properties differ.
