Group 17 elements have 7 valence electrons, one electron less than the maximum number of electrons that can be accommodated in the outermost shell. Therefore, it is easier for these elements to gain an electron and form uninegative anions, so as to attai
Why is oxygen in group 16 on the periodic table? Explain why ionic compounds are capable of conducting electricity. Why does carbon form covalent bonds? What is unique about halogens? What is the difference between halogens and chalcogens? Why are covalent bonds between hydrogen and nitrogen or...
What are the elements found in an A group (groups 1, 2, and 13-18) on the periodic table (also called representative elements)?What is the symbol of the element in Group 4A(14) and Period 2 in the periodic table?Which elements in the periodic table...
My literature quest for a “fluorine partner” has been unbiased, and it encompassed many different s-, p-, d-, and f-block elements, thus both main group as well as transition and post-transition metals. The fact that Ag2+—which is isoelectronic to Cu2+—has popped out seems to be...
What are the elements called that are found in an A group (groups 1, 2, and 13-18) on the periodic table (also called representative elements)? Which group of the periodic table is known as the halogens? List them. What are the names given to the following groups of...
Are all halogens oxidizing agents? Why are halogens and alkali metals likely to form ions? Why are halogens called halogens? Which of the halogens is the strongest oxidizing agent? Why are the Group 17 elements called halogens? Why are halogens found in nature only in compounds? How reac...
Special attention has been paid in numerous studies on triel bonds that are formed between elements of the 13th group (triel elements) acting as electrophiles and the electron-rich sites of Lewis base units [23,24]. The triel trivalent centers possess six electrons in the valence shell, thu...
