Malonic acid has pKa values of 2.83 (pK1) and 5.69 (pK2). If malonic esters are used then on treatment with a strong base like sodium ethoxide, the methylene (-CH2-) hydrogen can be deprotonated, but I am not sure if that is possible for malonic acid as that will lead to a tri-anion.
Zinc (Zn) typically has 30 protons in its nucleus. However, with a positive 2 charge, it has lost two electrons, leaving it with a net charge of +2. This does not change the number of protons, which remains at 30.
In covalent bonds, electrons are shared between atoms, not protons. In ionic bonds, one atom loses electrons (becomes positively charged) and another atom gains those electrons (becomes negatively charged), but protons remain inside the nucleus and are not shared, gained, or lost in the bond formation process.
No, changing the number of protons in an atom changes the element itself. Ions are formed by gaining or losing electrons, which does not change the number of protons in the nucleus.
When an amino acid becomes an ion (by gaining or losing a proton), the amino group (NH2) becomes NH3+, the carboxyl group (COOH) becomes COO-, and any side chain functional groups may be affected depending on their specific properties. The net charge of the amino acid will depend on the balance of protons gained or lost.
Conjugate acid
Oxygen has 8 protons, helium has 2 protons. To convert oxygen to helium, 6 protons has to be lost by nuclear disintegration which is not possible.

If an atom has lost more protons than electrons, it becomes a positively charged ion. This is because it now has more positive charge (from the protons) than negative charge (from the electrons), leading to an overall positive charge.
If there are 4 electrons and 4 protons, the atom is electrically neutral since the positive charges from the protons balance out the negative charges from the electrons. No electrons are lost or gained in this scenario.
Krebs Cycle is also known as the Citric Acid Cycle. The citric acid cycle begins with acetyl-CoA transferring its two-carbon acetyl group to the four-carbon acceptor compound (oxaloacetate) to form a six-carbon compound (citrate). The citrate then goes through a series of chemical transformations, losing first one, then a second carboxyl group as CO2. The carbons lost as CO2 originate from what was oxaloacetate, not directly from acetyl-CoA. The carbons donated by acetyl-CoA become part of the oxaloacetate carbon backbone after the first turn of the citric acid cycle. Loss of the acetyl-CoA-donated carbons as CO2 requires several turns of the citric acid cycle. However, because of the role of the citric acid cycle in anabolism, they may not be lost since many TCA cycle intermediates are also used as precursors for the biosynthesis of other molecules.[4] Most of the energy made available by the oxidative steps of the cycle is transferred as energy-rich electrons to NAD+, forming NADH. For each acetyl group that enters the citric acid cycle, three molecules of NADH are produced. Electrons are also transferred to the electron acceptor FAD, forming FADH2. At the end of each cycle, the four-carbon oxaloacetate has been regenerated, and the cycle continues
Electrons are these particles.
A neutral atom of a chemical element has a constant number of protons and electrons; loss or gain of electrons transform this atom in an ion.After the change of the number of protons the identity of the atom is lost.
The species that remains when an acid has lost a proton is called the conjugate base of the acid. It is formed by the acid donating a proton (H+) and becoming negatively charged. The conjugate base has one less proton compared to the original acid.
