Why is electron capture accompanied by the emission of an X-ray?

Chemistry
1 answer:
marissa [1.9K]2 years ago
8 0

Answer:

  During electron capture, an inner electron usually from K shell or L shell combines with proton of the nucleus thereby changing proton to neutron. The process of electron capture is also accompanied by the emission of neutrino. It generally occurs in proton rich nucleus. The capture of electron by the proton creates a hole in the electron shell. The hole created is generally filled by the dropping down of a higher level electron with the emission of X -ray.

The electron configuration of an element is 1s22s22p4.
MissTica

The likely thing which happens when two atoms of this element move toward each other is covalent bonding.

<h3>What is Covalent bonding?</h3>

This involves the atoms of element sharing electrons in order to achieve a stable octet configuration.

The element is oxygen which has an atomic number of 8 and needs two electrons to complete its outermost shell which results in the formation of two covalent bonds.

How do weather models predict the weather?
strojnjashka [21]

Answer:

<em>Weather forecasters often discuss the models they use to help predict the weather. ... Weather observations (pressure, wind, temperature and moisture) obtained from ground sensors and weather satellites are fed into these equations. The observations are brought into the models in a process known as data assimilation.</em>

Are s blocks metals ?
Mamont248 [21]
Yes, S-blocks are metals except for helium and hydrogen.  The S-block metals are shiny, silvery and relatively soft, although they can easily lose electrons.  Helium and hydrogen have valence electrons but also lack some similar properties as the other metals.
