Which elements are most likely to lose electrons combining with other elements?
the elements which have 1, 2 or 3 electrons in their valence (outermost)shells are most likely to lose electrons compared to the other ones and we name them as metals and alkaline earth metals. these elements want to give their outermost shell electrons to become more stable. because when they give those electrons the next shell under this one which has 8 electrons (2 in some cases such as lithium) becomes the new valence shell so the electron configuration resembles a noble gas.
How many bonding electrons does oxygen have?
The valence electrons are the electrons in the partially filled outermost shell (or shells).Simplified; Oxygen has the shells filled in the following way.1s22s22p4The 2s and 2p subshells make up the outer most shell for oxygen. In the 2p subshell, It is stable with 6 electrons but with oxygen only has 4. The subshell has 3 different orbitals which can contain 2 electrons in each. This means that 1 of the orbitals is completely full while the other two only have one electron. From this we can say that there are 2 bonding valence shell electrons. Because there is a possibility of having a total of 8 electrons in the 2nd shell, this means that there must be 4 electrons which are non bonding in oxygen's valence shell.
How many electrons would you expect chlorine with an atomic number of 17 to have in its outer shell?
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
How can an atom that has seven valence electrons complete its outermost level?
Look at the first element on the periodic table. The first energy level holds only two electrons, so Helium has filled its outer energy level. Atoms with an outer energy level that is not fill will fill it up by bonding with other atoms and sharing electrons.
What property of elements is used to organize the periodic table?
There are many factors that go into how elements are arranged in the periodic table. The main factor is that they increase left to right by atomic number. Elements are also grouped by families (columns) and periods (rows). Elements of the same family have the same number of valence electrons and also will have similar properties. Certain families will thus bind well ith each other while others will not. Though not organized as so, atomic mass usually increases with atmic number, but there are some exceptions to this.
How many electrons will thallium has in its outermost shell?
thallium has 3 electrons in outermost shell.
How many element do the elements belonging two group IIIA have in there outermost shell?
Group 3 is part of the transition metal series. This means that the number of outer shell electrons the element has will depend on its oxidation state.
How many electrons does copper have in its outermost shell?
The answer is 4s, because it is in the 4rth period of the Periodic Table of Elements =]
How do 3a differ from other group of elements?
The group 3 of the periodic table include lanthanides and actinides.
What element in period 3 consist of 3 electrons in its outermost shell?
aluminium

What is the number of electrons found in the outermost electron shell in aluminum?
Normally, three.
What do atoms in the same period have?
Their outermost electrons are in the same shell. For example, Helium and Hydrogen have 1 and 2 electrons respectively, and these electrons exist within the first electron shell. Lithium has 3 electrons and the third of these electrons is in the second electron shell, and so, it is a member of the 2nd period of the periodic table.
What is different in number of shells in magnesium and sulphur?
There are no difference in the number of shells in magnesium and sulphur. Both elements contain 3 shells. However, the total number of electrons in the shells are different. Magnesium has 12 electrons in its shells whereas sulphur has 16 electrons in its shell. In addition, the electrons in the valence shell (outermost shell) are also different. Magnesium has 2 electrons in its valence shell whereas sulphur has 6 electrons in its valence shell.
How many electrons does phosphorus have in its valence shell?
The atomic number of phosphorus is 15.its electronic configuration is 2,8,5.outermost shell has 5 electrons. it can accommodate 3 more electrons to complete its octet.so its valency is 3. and it has 5 electrons on its valence shell.
Why is aluminum plus 3?
Because there are 3 electrons in its outermost shell, to reach the nearest noble gas electronic configuration it loses 3 electrons .
How many electrons are found in the outermost shell of aliminum?
Aluminum has an atomic number of 13. Thus, neutral aluminum has 13 protons and 13 electrons. Therefore, its electron configuration is 1s2 2s2 2p6 3s2 3p1. We can see that 3 is the outermost shell and that there are 3 electrons found there.
