The chemical formula : X₃Y₂
<h3>Further explanation </h3>
The noble gas element is a stable class of elements. The noble gas element is monatomic. Stability of noble gases is caused by an electron configuration that has a stable configuration of 8 (has 8 valence electrons) except He with a duplet configuration (has 2 valence electrons)
Other elements that do not yet have electron configurations such as noble gases will try to achieve their stability by forming bonds between elements.
This is generally called the octet rule
X has 2 valence electrons.to achieve stability, element X will release 2 electrons to form X²⁺
Y has 5 valence electrons, to achieve stability, the element Y will attract/ add electrons to form Y³⁻
The two compounds will form a compound with the charges crossed : X₃Y₂
Lymphocytes and the other formed elements are developed from pluripotent stem cells. The pluripotent stem cells generate myeloid stem cells and lymphoid stem cells. Myeloid cells start and complete their development in red bone marrow and give rise to red blood cells, platelets, eosinophils, basophils, neutrophils, and monocytes. Lymphoid stem cells begin development in the red bone marrow, but some are completed in the lymphatic tissues, where they give rise to lymphocytes. The B cell lymphocytes begin and finish in the red bone marrow and the T cell lymphocytes begin in the red bone marrow, but they mature in the thymus.
