What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
How many valence electrons does a chlorine atom have if its electron configuration is Ne3s23p5?
With an e- configuration of [Ne] 3s23p5, the atom will be found in Group VII A, meaning that there are 7 valence electrons.
What element has the configuration 2 8?
Neon - one of the stable and unreactive elements of group 8.
What is the group number for nitrogen?
the group number for nitrogen is group 15.
How did scientists discovering protons and neutrons help them to place elements in their correct order and group?
By discovering the elements proton number, it became easier for scientists because the elements had similar properties. And they could arrange it by increasing proton number, valence electrons or electronic configuration.
What is the relationship between electronic configurations and an element's group number?
apples are round
Atoms of elements with the same electron configuration are organized in in the Periodic Table?
They are not! It is a prevalent myth that the elements are organized so that elements with the same configuration are organized into the same group, but all that really matters is the number of valence electrons, and that much is guaranteed by the arrangement in order of atomic number.So we have for example in group 10, Ni with configuration [Ar] 3d8 4s2 , Pd with configuration [Kr] 4d10 , and Pt with configuration [Xe] 4f14 5d9 6s1.Group 4 is characterized (supposedly) by the electron configuration d2 s2 but thorium which has this configuration is not placed in this group but in the actinides.
The correct electron configuration for aluminum?
The electronic configuration for aluminum is 1s22s22p63s23p1 .
In which period and group is the element whose electron configuration is Kr5s1?
Group 1- as the configuration is ns1. The Kr in the question indicates the Krypton core. The 5s1 is the clue - the period number is the same as the principal quantum number (in this case 5) so the element is in group 1 and period 5 - so it is rubidium.
What correctly depicts the relationship between group cohesiveness and group productivity?
When a group is too cohesive, productivity can suffer.
How does the electron configuration of an ion of a group 1A or group 7A element compare to that of the nearest noble gas?
What relationship exists between the electron structure of Group IA ion and the electron structure of the nearest Noble Gas?
Inter group relationship during pre colonial era?
Inter-group relationship of pre-colonial era between Hausa, Igbo, Yoruba.
What is the relationship between column numbers and number of valence electrons?
theses are not called colmns but are called groups of periodic table.the relation between them is that in the periodic table the elements are placed in such a way that the the number of electrons in the outermost shell are equal to the group number.
Which number tells you the number of valence electrons?
The group numbers tell the number of valence electrons. Without looking on the group number you can also tell the number of valence electrons by looking at the highest energy level in the electronic configuration.
What are the group of etnolinguistik?
Ethnolinguistics is a study of the relationship between language and culture in any group of people. Ethnolinguistics is a cross between ethnology and linguistics.
What is the link between group number and number of outer electron?
The number of outer electrons is the same as the group number.
General electronic configuration of group having low ionisation energy?
The general electron configuration of the group having the lowest ionization energy is [Noble gas configuration]xs1. In this case, x is the principal quantum number of the valance electron. The noble gas configuration may either be written out in full or denoted by the noble gas' atomic symbol in brackets (ie [Ne]).
