Answer:

there are 8 electrons

Explanation:

Calcium is a transition element present in the D block of the periodic table. Calcium has atomic number 20. So its electronic configuration is 2, 8, 8, 2 by the Afbau rule. 2, 8,8 and 2 electrons are present in K,L, M and N shells of the atom. So, we can say that the number of electrons in the third energy level of a calcium atom are 8.

Explanation:

a) <em>Fixed points</em> are the temperatures at which a thermometer is calibrated. They can refer either to the actual temperatures used for calibration, or the thermometer readings at those temperatures.

b) <em>Fundamental interval</em> is the difference between the fixed points. As with fixed points, it can refer either to the difference in actual temperature, or the difference in the corresponding thermometer readings.
