Kilograms represented by the mass defect for thorium -234=3.09x 10-27 kg what is the nuclear binding energy for thorium -234

Mass defect and binding energy are related as

ΔE = Δmc^2

Where

ΔE = binding energy

Δm = mass defect

c = speed of light

given

mass defect = 3.09x 10-27 kg

We know that speed of light = 3 X 10^8 m /s

ΔE = 3.09x 10-27 kg  (3 X 10^8 m /s)^2 = 2.781 X 10^-10 J / Kg

both adhesion and cohesion are attractions.

they are different in that adhesion is the force of attraction between the molecules of two different substances, whereas cohesion is the force of attraction between molecules of the same substance.

possible examples include capillary action, in which the adhesion between water and glass causes the water to rise in a narrow tube against the force of gravity.

because of hydrogen bonding, water is extremely cohesive.

this causes molecules on the surface of water to be drawn inward, which is why drops of water form beads on smooth surfaces.

hope this .

explanation:

let the different atoms be x and y. each with four protons and same mass will be represented as follows.

mass number is number of protons + number of neutrons.

            and  

since, it is given that one has a negative charge while the other is neutral. therefore, there will be increase in number of protons and the atom will be represented as follows.

according to periodic table, mass number of beryllium is 9 and it has atomic number 4 so, the atoms will be and .  

the protons and neutrons will be located inside the nucleus whereas the electrons will be revolving around the nucleus.
