To examine: The periodic table to find of two elements are in the same row and their common property.
Introduction: The periodic table of chemical elements shows all the chemical elements listed ina tabular form according to their atomic number, electron distribution, and similar chemical properties. The horizontal rows in the periodic table are called periods, whereas the vertical columns of the periodic table are called the groups. All elements in a group have the same number of electrons in their outermost atomic orbital. All elements in a period have the equal number of electronic shells. From left to right in a period, each element adds one electron and a proton, thus increasing the atomic number.

To predict: Whether similar chemical properties would be of elements that belong to the same row or the same column.

- Please help me calculate drug dosage from the following information: Patient weight: 35 pounds, so 15.9 kilograms (got this by dividing 35 pounds by 2.2 kilograms) Drug dose: 0.05mg/kg Drug concentration: 2mg/mLarrow_forwardA 25-year-old woman presents to the emergency department with a 2-day history of fever, chills, severe headache, and confusion. She recently returned from a trip to sub-Saharan Africa, where she did not take malaria prophylaxis. On examination, she is febrile (39.8°C/103.6°F) and hypotensive. Laboratory studies reveal hemoglobin of 8.0 g/dL, platelet count of 50,000/μL, and evidence of hemoglobinuria. A peripheral blood smear shows ring forms and banana-shaped gametocytes. Which of the following Plasmodium species is most likely responsible for her severe symptoms? A. Plasmodium vivax B. Plasmodium ovale C. Plasmodium malariae D.
