I would say mass lost by nuclear collisions. The mass defect is the mass difference between the mass of an atomic nucleus and the sum of the mass of its constituent particles. It equals the energy given off in the formation of the nucleus.

An isotope, X, of a particular element has an atomic number of 8 and a mass number of 18. Therefore:
GarryVolchara [31]

Answer:

D

Explanation:

Because the atomic number is 8, we can see that it is indeed an isotope of oxygen. If the mass number is 18, this means that the protons and neutrons added together = 18, so there are 10 neutrons. It does not have an atomic mass of 15.9994 like the element on the periodic table, however, as this is a confirmed isotope and not an average.

why is there a dip in ionization energies between the elements Be and B, between Mg and Al, and between Ca and Ga?
expeople1 [14]
Be and B: Be is 1s2 2s2 and B is 1s2 2s2 2p1
Be has full 2 orbitals and so does B but B only has 1 electron in p so it is really unstable and easy to react. So there is a dip in ionization energies. The other questions are similar to this so if you need, feel free to ask me

A common antacid contains the acid-neutralizing agent sodium hydrogen carbonate. Write the chemical formula for sodium hydrogen
kaheart [24]
Sodium hydrogen carbonate has:
sodium \:  ion ( {Na}^{+}), hydrogen \\  ion ( {H}^{+}), and \:  carbonate \\ ion ( {CO3}^{2-})
The + from Na+ and + from H+ makes 2+, and therefore the 2- from CO3 evens the charges to neutral.

Not to be confused with Sodium Carbonate, (Na2CO3), which lack an H, Sodium Hydrogen Carbonate is sometimes shortened to just Sodium Bicarbonate. It is used in the kitchen (cooking) as "baking soda."

Formula: NaHCO3
