What is a pseudo noble gas configuration? Electron Configuration The electron configuration of an atom shows the placement of electrons around the atom's nucleus. The outer most electrons reside in what is known as the valence shell. The electrons in the valence shell are responsible for the sha...
What is a group and period in the periodic table? How are the elements arranged into groups and periods in the modern periodic table? What is the history of the periodic table? Why are the transition metals 10 columns wide on the periodic table?
Groups are often more indicative of an element's properties than periods, as elements in the same group react similarly. For example, noble gases in Group 18 are all inert because their outer shell is full, making them unreactive. In contrast, the transition across a period from one element...
For a substantial period in history Scotland remained a unified state independent of Britain. Edinburgh is its capital. Tourism is one of Scotland's most important and industries. Tourists from all over the world come to enjoy the beauty of a Scottish scenery,to drink scotch whiskey and to ...
CIf assertion is true but reason is false. DIf assertion and reason both are false.Submit An element Y is in second period and group 16 of the periodic table: (i) Is it a metal or non-metal? (ii) What is the number of valence electrons in its atom? (iii) What is its valenc...
Classify Element 79 as metal, nonmetal, or metalloid. Is it a noble gas as well? Which group of elements belongs to the f-block? (a) inner transition metals (b) metalloids (c) metals (d) nonmetals. What are the 4 categories of elements included in the Periodic Table?
Noble gas elementsare mostly inert, so they tend not to form compounds. So, the easiest way to find the answer to which noble gas is the heaviest or most dense is to find the element in the group with the highest atomic weight. If youlook at the noble gas element group, the last el...
He is a noble man who would never put his family in jeopardy. Humble Thinking lowly of one's self; claiming little for one's self; not proud, arrogant, or assuming; thinking one's self ill-deserving or unworthy, when judged by the demands of God; lowly; waek; modest. God resisteth...
one of the step says "Determine the total number of electrons required for each atom in teh structure to achieve a noble gas configuration. This would be 8 electrons for C and 8 electrons for O (to fill their respective valence energu levels and 2 electrons for H."why is it 8 ...
Periodic Table Group: An important part of chemistry is being able to understand the various useful features of the periodic table of the chemical elements. These features include the atomic number, row position and column position of each element. Each row is a period and each column is a gr...
