When equation decays in part of the uranium decay series, there are two pathways, one of alpha emission and one of beta emission. When equation emits a beta particle, what is the product?

The product of emission of beta particle from uranium 238 will be Uranium 239

Explanation:

There are two type of beta decay

β− decay and β+ decay

Let us assume here the decay is β− decay for Uranium 238

Uranium 238 will decay β− to produce Uranium 239

Hence, the product of emission of beta particle from uranium 238 will be Uranium 239

answer: atomic mass was originally used to arrange elements on the periodic table, but is no longer used to organize the modern version.

explanation:

originally atomic mass was used to arrange elements on the periodic table from left to right in a row. each column then shows similar properties of elements of a group.

in modern periodic table, the atoms are arranged in increasing atomic number. as atomic number represents the number of protons in an atom which is unique for every atom.
