What is the only element without neutrons?
The only element without any neutrons is Hydrogen-1, which has a lone proton.
Do amines tend to be acid neutral or basic?
Amines are basic due to the presence of lone pair of electrons on Nitrogen atom they may accept a proton from an acid.
Why ammonia is stronger base than aniline?
The lone pair on the nitrogen of aniline is delocalised into the pi-system of the benzene ring and is therefore less available for attack on a proton.
Where is the most mass of an atom?
Almost all of the mass of an atom is in the nucleus. The nucleus is made up of protons and neutrons, with hydrogen-1 as the lone exception because its nucleus has only a proton in it. In other atoms, protons and neutrons are fused together to form that nucleus. The electrons are out in their electron cloud. And we mention the electron because it has only about 1/1836th the mass of a proton. See how it works? A fistful of electrons weigh almost nothing compared to a single proton. The neutron is slightly heavier than a proton, so when neutrons and protons are gathered in any atomic nucleus, it contains most all of the mass of that atom.
Why is ammonia a base?
Ammonia is a base because it reacts with acid to form a salt. The lone pair of electrons on the nitrogen donate to a proton producedc by acids. It also has a pH of more than 7 and it dissolves in water.
Is NH3 a proton acceptor?
It has a lone pair.So it is a proton acceptor
Why is the H ion referred to as a proton?
Most hydrogen ions are simply protons. They have no neutron associated with them, and because they are ions, there is no electron. If the hydrogen is known to have no neutron, it is called protium. For practical proposes, there is no distinction between a protium ion and a proton that is not part of a nucleus. Some hydrogen ions are not simply protons, however, and have an associated neutron. In this form, the hydrogen is referred to as deuterium. When hydrogen has two neutrons, it is called tritium, and is radioactive.
What does D2O stand for?
D2O stands for Deuterium Oxide. It is also known as Heavy water. It is widely used as moderators in nuclear reactors. Deuterium is a isotope of Hydrogen, with a neutron along with the lone proton, that is why it is called heavy water.
What happend to lone neutrons?
A neutron has a lifetime of about 15 minutes. This means that if you wait roughly 15 minutes there is a good chance the neutron will have decayed into other particles. So lone neutron just decay quickly, that is why there aren't any around. A neutron in an atomic nucleus is stable however (fortunately for us!).
What is meant by when there are two lone electons?
Called lone pair(s) of electrons,this exists when the atom such as Nitrogen in the ammonia has pair of electrons used to form what is called coordination bond as the lone pair of nitrogen occupy an vacant orbital like the orbital of the hydrogen proton released from acids. lone pair of ammonia + vacant orbital of hydrogen proton = Ammonium ion
What is the only element without neutrons?
The only element without any neutrons is Hydrogen-1, which has a lone proton.
The three particles that make up an atom are?
The electron, the proton and the neutron are the "building blocks" of the atom. Protons have a positive electrical charge (p+), and neutrons which have about the same mass, are electrically neutral, or have no electrical charged (n0). Electrons, which are much less massive than protons - only about 1/1836th as heavy - have a negative electrical charge (e-). All atoms are made of protons, neutrons and electrons, though most hydrogen (1H1) has just the proton in its nucleus and a lone electron in orbit.

How are acids and bases different?
Because an acid produces a hydrogen ion (H+) as it disassociates in water, while a base produces a hydroxide ion, (OH-) as it disassociates in waterDepends on the definition of acid and base.Bronsted acid is a proton donor (HCl)Lewis acid is a lone pair receptor (anything with an open orbital)Bronsted base is a hydroxide donor or proton receptor (KOH)Lewis base is a lone pair donor.
