Considering the elements of period 3 in the modern periodic table, answer the following questions:(A) Name the 'element' in which all the shells are completely filled with electrons.(B) Name the element which has one electron in the outermost shell.(C) State the most electronegative element in this p​

Answer»

tion:(a) The element is silicon. d-first shell is COMPLETELY filled and valence shell has THREE electrons so its electronic configuration will be 2,3. THEREFORE the element is Boron. e-first shell can have two 2 electrons.(b) So, LITHIUM, SODIUM, and Potassium are the 3 elements that have a single electron in their outermost orbit.(c) Thus, fluorine is the most electronegative element, while francium is one of the least electronegative.

An electromagnetic FIELD (also EM field) is a CLASSICAL (i.e. non-quantum) field produced by accelerating electric charges.[1] It is the field described by classical electrodynamics and is the classical counterpart to the quantized electromagnetic field TENSOR in quantum electrodynamics. The electromagnetic field propagates at the speed of light (in fact, this field can be identified as light) and interacts with charges and currents. Its quantum counterpart is ONE of the four fundamental forces of nature (the others are gravitation, weak interaction and strong interaction.Explanation:
