The number of protons, neutron, and electrons present in calcium. Introduction: In the modern periodic table, elements are arranged according to their increasing atomic number. The symbol is derived as, X Z A . In case of calcium, the symbol is represented as C 20 40 a where “Ca” represents the chemical formula of calcium. A is the atomic mass which is equal to the sum of the number of protons and the number of neutrons which is 40. Z is the atomic number which is equal to the number of protons which is 20. The nucleus is defined as the sum of the number of neutrons and protons. p + → p r o t o n n 0 → n e u t r o n e − → e l e c t r o n

Summary Introduction

To analyze:

The number of protons, neutron, and electrons present in calcium.

Introduction:

In the modern periodic table, elements are arranged according to their increasing atomic number. The symbol is derived as, ${}_{Z}^{A}X$ . In case of calcium, the symbol is represented as ${}_{20}^{40}C a$ where “Ca” represents the chemical formula of calcium.

A is the atomic mass which is equal to the sum of the number of protons and the number of neutrons which is 40.

Z is the atomic number which is equal to the number of protons which is 20.

The nucleus is defined as the sum of the number of neutrons and protons.

A sample of blood was taken from the above individual and prepared for haemoglobin analysis. However, when water was added the cells did not lyse and looked normal in size and shape. The technician suspected that they had may have made an error in the protocol – what is the most likely explanation? The cell membranes are more resistant than normal. An isotonic solution had been added instead of water. A solution of 0.1 M NaCl had been added instead of water. Not enough water had been added to the red blood cell pellet. The man had sickle-cell anaemia.

With reference to their absorption spectra of the oxy haemoglobin intact line) and deoxyhemoglobin (broken line) shown in Figure 2 below, how would you best explain the reason why there are differences in the major peaks of the spectra? Figure 2. SPECTRA OF OXYGENATED AND DEOXYGENATED HAEMOGLOBIN OBTAINED WITH THE RECORDING SPECTROPHOTOMETER 1.4 Abs < 0.8 06 0.4 400 420 440 460 480 500 520 540 560 580 600 nm 1. The difference in the spectra is due to a pH change in the deoxy-haemoglobin due to uptake of CO2- 2. There is more oxygen-carrying plasma in the oxy-haemoglobin sample. 3. The change in Mr due to oxygen binding causes the oxy haemoglobin to have a higher absorbance peak. 4. Oxy-haemoglobin is contaminated by carbaminohemoglobin, and therefore has a higher absorbance peak 5. Oxy-haemoglobin absorbs more light of blue wavelengths and less of red wavelengths than deoxy-haemoglobin
