Alkali metals
Hydrogen only needs one more valence electron to fill it's out shell. So it belongs with the alkali metals.
Answer : The chemical symbol for the element that results from this process is, (Ar) for argon.
Explanation :
Electron capture : In this decay process, a parent nuclei absorbs an electron and gets converted into a neutron. Simply, a proton and an electron combines together to form a neutron. Mass number does not change in this process.

The equation for the given reaction is,

Thus, the chemical symbol for the element that results from this process is, argon (Ar).
Water , H2O, is a molecule made of oxygen and hydrogen. The bonds that hold water molecules together are due to shared ELECTRONS, and known as covalent bonds
Hopefully you get the correct answer I just need points
