Answer
is: mass number stays 184, but atomic number changes.<span>
Beta decay is radioactive decay in
which a beta ray and a neutrino are emitted from an atomic
nucleus.
There are two types of beta
decay: beta minus and beta
plus. In beta minus decay (</span>atomic number Z is increased by one, new element is wolfram W) neutron is converted to a
proton and an electron and
an electron antineutrino.
In beta
plus decay (atomic number Z is decreased by one, new element is hafnium Hf), a proton is converted to a neutron and positron and an electron neutrino, so mass number does not change.

Answer:
Graduated cylinders are designed for accurate measurements of liquids with a much smaller error than beakers. They are thinner than a beaker, have many more graduation marks, and are designed to be within 0.5-1% error. ... Therefore, this more precise relative of the beaker is just as critical to almost every laboratory.
Explanation:
hope this helped!
This is called as such because the proton or H+ has taken on both lone electron pairs on the oxygen in the water molecule. As such it is s coordinate covalent bond.
