Be is in the s block too. Li has one less proton than Be.
Protons are part of the nucleus, so they have less mass than the nucleus (except in the specific case of hydrogen, where the nucleus is a single proton so they have the same mass).Electrons are much less massive than protons. It would take 1836 electrons to equal the mass of one proton.Neutrons are very slightly more massive than protons, by just about the mass of an electron. They're close enough that they're generally treated as having essentially the same mass.
It is the atom of deuterium. Its nucleus is composed of a proton and one neutron. The atom has one electron that is orbiting around the nucleus.
Tin's atomic number is 50. Thus, it has 50 protons per atom. The atom with 51 protons is antimony.
Less.
In charge, spin, and strangeness; they are exactly equal. In mass, it would take about 1836 electrons to equal a proton.
Yttrium
Chlorine, with the atomic number 17 has one less proton than argon, with the atomic number 18. The atomic number is the number of protons.
A proton has slightly less mass than a neutron.
k
Actually every proton has different size in different nucleus. But in general, Proton, 1x10-15 m or "a diameter of approximately one-millionth of a nanometer". The electron, the diameter is less than 1x10-18 m. Likewise, The diameter of an electron is less than 1/1000 the diameter of a proton.
Boron.
Nitrogen atoms have 7 protons in their nuclei. You can know this because the atomic number of nitrogen is 7, and the atomic number is the number of protons. So the element that has one less proton than nitrogen in the nuclei of its atoms is carbon, which is atomic number 6, so it has 6 protons in the nuclei of its atoms.
negatively charged ion.
A hydrogen atom, H, is a proton (as nucleus) with one electron orbitting around it. A proton is just (the same as above) one proton, which lacks the electron: H+ .
The atomic number is equivalent to its number of protons. One proton in atom is its atomic number is 1. Hydrogen is the only atom with one proton.
It can. This is an isotope of hydrogen called deuterium. However, deuterium accounts of less than 0.04% of all hydrogen by mass.
If a proton on N between two C=O's is removed by a base, one can draw two resonance structures, one involving each C=O, to stabilize the resulting anion. However, with an amide, there is only one C=O and when the H is removed, only one resonance structure can be drawn. As a result, the amide H is less acidic than the imide H.
