What do you notice about the number of energy levels in an atom of an element in the period the element is in?
The atom of an element in the third period of the Periodic Table has 3 energy levels and so on. Also, atoms of elements in the same group have the same no. of valence electrons.
What is the element that has the smallest atomic number of all the elements and that has electrons in three different energy levels?
If it has electrons in three different energy levels, then it must be in period 3 of the periodic table. To have the fewest electrons, it would be in group 1. So, the element in group 1, period 3 is sodium (Na).
What element has 2 valence electrons and 4 energy levels?
The element magnesium has four electron energy levels and two electrons in its outer energy level in the neutral atom. Use the link to Wikipedia for more details.
As you move down a group elements have how many electrons shells than those above them?
going down a group, each element gains 1 shell (energy levels)
How does the number of electrons in outer energy levels relate to the position of an element in the periodic table?
the group number shows the number of electrons in the outermost energy levels. forexample sodium (Na) have 1 electron in the outermost shell and is placed in the group 1. Elements are grouped in rows depending on their energy levels, or valence electron numbers. Columns of elements are those that are chemically similar, or react
How many electrons does Arsenic have in each of its energy levels?
arsenic belongs to V-A group of periodic table it has 5 electrons in its outermost energy level.
What do Valence Electrons determine?
The Group Number of the Element you're working on determines the number of Valence Electrons. Valence electrons are electrons in the outside energy level.
What is the number of electrons in the highest occupied energy level of an element in Group 15?
5 valence electrons.
What do you notice about the energy levels in an atom of an element and the period the element is in?
the period number tells which is the highest energy level occupied by the electrons
What group has a complete set of valance electrons in their outer energy levels?
Group 18 or noble gases.
What element has 5engry levels and is in group 2?
Strontium has 5 energy levels in group 2.It is represented by symbol Sr and has five energy levels K,L,M,N and 0.
What trend is oberserved among the atomic radii of main-group elements down a group. eplain this trend?
The trend of atomic radius increases down a group on the periodic table. This occurs because each successive element down a group has another energy level. As more electrons are added, more energy levels are needed to hold the electrons.
