Which elements have electron configurations that end in ns 2 np 5?
The elements with the electron configurations that end in ns 2 and np 5 are halogens, group VII A elements.
What element electron configurations would represent a halogen?
The halogens are is group VII (17), and thus they all have 7 valence electrons. These will be located in different energy levels for the different halogens, but since they are all also p-block elements, they will all have ns^2 np^5 electron configurations, where n is the period number. Examples: Cl will be [Ne] 3s^2 3p^5 and Br will be [Ar] [Ar] 4s2 3d10 4p5 (note the inclusion of the d-block electrons for Br).
What is the chemical symbol for Neptunium?
Electron configuration of neptunium: [Rn]7s26d15f4
What is the first transuranium element?
Transuranium elements are those that have an atomic number greater than uranium's, which is 92. The first transuranium element is neptunium (Np) with atomic number 93.
Main block elements?
p-block elements are the elements in which the last electron entres np orbital.which include six groups of elements i.e. group 13 to 18.boron family,carbon family,pnicogens,chalcogens,halogens and noble gases. Thank you

How is neptunium similar to plutonium?
Similarities: - Np and Pu are radioactive, unstable chemical elements - Np and Pu are man made - Np and Pu are dangerous - Np and Pu are fissionable with thermal neutrons
What type of particle is emitted when U-235 decays to Np-235?
It is the reverse: Np-235 decay to U-235 by electron capture.
What is the electron configuration of a atom?
The halogens are is group VII (17), and thus they all have 7 valence electrons. These will be located in different energy levels for the different halogens, but since they are all also p-block elements, they will all have ns^2 np^5 electron configurations, where n is the period number.

There are 92 elements from hydrogen to uranium that occur in which manner?
All these 92 elements (including also Np and Pu) are considered now natural elements.

What is different about all the elements listed after uranium?
All are radioactive, artificial elements (but note that Np and Pu can exist also naturally in extremely low concentrations).
