Tin, because it has five energy levels with four electrons in the fifth level
.
Explanation:
Tin has an electronic configuration as
1s2,2s2,2p6,3s2,...........4d10, 5s2,5p2
They have four valence electrons in their outer shell
Among the four diagrams given Tin is least reactive because the atomic radius of tin is largest among all four options. Due to large atomic radius electronegativity decreases and hence Tin is the least reactive element among Neon, Chlorine, gallium and tin.
The electronegativity of an element is its tendency to complete its octet by attracting electrons towards itself. Also tin is at the lowest place in the periodic table among all the four mentioned elements, its ionization energy is also low hence less electronegative and least reactive.
Yes it is an example of friction.Also a sled sliding across the snow or ice
For patients with newly diagnosed high-grade gliomas , Cabozantinib at a dose of 40 mg daily with RT + TMZ and post-RT TMZ was generally well tolerated.
<h3>How would you define diagnosed?</h3>
The procedure of determining a diagnosis, disease, or injury based on its indications and symptoms. To aid in the diagnosis, testing like blood tests, imaging tests, and biopsies may be done in addition to a physical examination and health history.
<h3>How do doctors make their diagnosed?</h3>
A doctor or other healthcare professional often makes a diagnosis after a physical examination and a thorough review of the patient's medical history. The next step is to prescribe tests and other diagnostic procedures to identify the underlying disease or injury that is causing the symptoms.
