What is NP4 Hume pipe?
It is Reinforced Concrete, Heavy Duty, Non-pressure Pipes.
What is the general electronic configuration of p block elements?
The general electronic configuration of p block elements is ns2 np1-6. This means that the outermost electron shell of p block elements contains electrons in either the np1, np2, np3, np4, np5, or np6 orbitals.
What is the most likely charge on an ion formed by an element with a valence electron configuration of ns2 np4?
The element with a valence electron configuration of ns2 np4 is sulfur (S). Since it needs to gain 2 electrons to achieve a stable electron configuration, it is most likely to form an ion with a charge of -2.
Where is the Big Pit in Wales?
Big Pit is South West Wales, here is the address:- Big Pit National Coal Museum Blaenavon Wales NP4 9XP
In groups 13 through 18 valence electrons may be in which sublevels?
In groups 13 through 18, valence electrons may be in the s, p, and d sublevels. Group 13 elements have valence electrons in the s and p sublevels, while group 14-18 elements may also have valence electrons in the d sublevel in addition to s and p sublevels.
How would you relate the number of valence electron to their group number in the periodic table?
The number of valence electrons in an element corresponds to its group number in the periodic table. Elements in the same group have the same number of valence electrons, which influences their chemical properties and reactivity. For example, elements in Group 1 have 1 valence electron, Group 2 have 2 valence electrons, and so on.
How many valence electrons does an atom have from group 16?
Atoms of elements in Groups 13-18 have 10 fewer valence electrons than their groups numbers.However , helium atoms have only 2 valence electrons.
