What element has a configuration of 2-8-6?
The element sulfur (element number 16) has an orbital configuration of 1s2 2s2 2p6 3s2 3p4.
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.
Sodium and potassium have similar chemical and physical properties This observation is BEST explained by the fact that both elements?
belong to the same group (Group 1) in the periodic table, which means they have the same number of valence electrons, resulting in similar chemical properties. Additionally, they have comparable atomic sizes and reactivity due to their outer electron configuration.
What is element Ar 3d104s24p5?
The element with electron configuration [Ar] 3d10 4s2 4p5 is Bromine (Br), which has an atomic number of 35. It belongs to the halogen group in the periodic table.
What is the valence electron configuration of each element in group 1?
All elements in group 1 have 1 valence electron.
What is the relationship between electronic configurations and an element's group number?
apples are round
Which group 0 2 5 or 7 atoms electronic configuration 3s2 3p5?
The group with the electronic configuration of 3s2 3p5 would be group 7, which is the halogens group. This configuration indicates that the atom has 7 valence electrons, matching the group number.
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.
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.
What correctly depicts the relationship between group cohesiveness and group productivity?
When a group is too cohesive, productivity can suffer.
Inter group relationship during pre colonial era?
Inter-group relationship of pre-colonial era between Hausa, Igbo, Yoruba.
What is the outer configuration for all group 1?
All group 1 elements have an outer configuration of ns1, where "n" represents the principal quantum number of the outer energy level and "s1" indicates one electron in the s-subshell.
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?
What is the link between group number and number of outer electron?
The number of outer electrons is the same as the group number.
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.
Which number tells you the number of valence electrons?
The group number in the periodic table tells you the number of valence electrons for main group elements. The group number is the same as the number of valence electrons, except for transition metals.
What group have element that has the electron configuration 1s22s22p63s23p63d14s2?
This electron configuration belongs to the element chromium, which has the atomic number 24. Chromium is a transition metal element.
