If a neutral atom with 88 electrons undergoes 2 rounds of beta minus decay, what will be the new element?

The new element will be thorium-226 (²²⁶Th).

Explanation:

The beta decay is given by:

Where:

A: is the mass number

Z: is the number of protons  

β⁻: is a beta particle = electron

: is an antineutrino

The neutral atom has 88 electrons, so:

Hence the element is radium (Ra), it has A = 226.

If Ra undergoes 2 rounds of beta minus decay, we have:

Therefore, if a neutral atom with 88 electrons undergoes 2 rounds of beta minus decay the new element will be thorium-226 (²²⁶Th).

in chemistry, adhesion and cohesion are attractive forces that exist between molecules. they hold the molecules together from each other. they are different in that adhesive force exists between molecules of different substance while cohesive force happens between molecules of same substance.

adhesion between water and glass causes water molecules at the edge of water and glass interface to climb up the wall in a narrow glass tube. this is called capillary action. cohesion is what gives glass its shape and causes water to form a droplet.
