Particle Physics

The element with 11 protons is sodium, and its elemental symbol is Na.

The electron configuration of a transition element in the Bohr model consists of electrons filling the principal energy levels (n = 1, 2, 3, etc.) and sublevels (s, p, d, f). Transition elements have partially filled d orbitals, so their electron configurations typically involve electrons filling the s and d orbitals. For example, the electron configuration of chromium (Cr) in the ground state is [Ar] 3d^5 4s^1.

The number of protons defines an element - the number of neutrons isn't needed to find the identity of the element. All ions and isotopes with 44 protons is ruthenium. However, with the information about the neutrons, we know the specific isotope: 101Ru.

Though a hydrogen atom typically has one proton, its mass is not solely determined by the proton. The mass of a hydrogen atom comes from the combination of the proton and an electron. The electron contributes a much smaller amount to the overall mass compared to the proton.

Antimatter is actually matter that can be considered going back in time. Negative matter is matter that has negative gravity properties. In other words, Negative matter repels things. Negative matter is also theoretical, not proven. Antimatter has been (and is being) made.

Rutherford called this phenomenon the "scattering of alpha particles" which was a key observation that led to the development of the nuclear model of the atom.

The general electron configuration for lanthanides is [Xe] 4f^n 5d^1 6s^2, where n ranges from 1 to 14 depending on the specific lanthanide element.

Scandium's, or Sc's, atomic number is 21. Its most common isotope has an atomic mass of 45. Since an electrically neutral atom's atomic number is equal to its number of protons as well as its number of electrons; and since the number of neutrons in a particular isotope of an atom is equal to its atomic mass minus its atomic number, the number of neutrons of the most common isotope of neutral scandium is 45 - 21 = 24.

Iron's atomic number is 26. Thus it has 26 protons and 26 electrons. The electronic configuration for the first 26 electrons, and so therefore iron, is Fe 1s2 2s2 2p6 3s2 3p6 4s2 3d6.

The shorthand electron configuration is Fe [Ar] 4s2 3d6.

The strong nuclear force is the fundamental force that holds the nucleus together by overcoming the electromagnetic force that causes protons to repel each other. This force acts over very short distances within the nucleus and is responsible for binding protons and neutrons together to form the atomic nucleus.

Covalent bonding. It can be two types - polar covalent or nonpolar covalent. In polar covalent bonding, atoms do not share electrons equally. In nonpolar covalent bonding, atoms share electrons equally.

The element with 5 protons and 4 electrons is boron (B). This means that it has a net positive charge of +1, since there is one more proton than electron.

particle whose dimensions is less then that of atom are said to be subatomic particle . they may be charged or uncharged .eg neutron is uncharged subatomic particle where as electron ,proton , positron are charged subatomic particle.

Quarks are subatomic particles that break and combine to form other particles through the strong force, which is mediated by gluons. Quarks are held together by this force to form protons and neutrons, which are the building blocks of atomic nuclei.

The chemical element, Radon, has an atomic number of 86, meaning it has 86 protons. Were there an isotope of Radon that had 136 neutrons, it would be labeled as 222Rn. Well, it turns out that this isotope does exist and has a half-life of 3.82 days.

The second electron shell can hold up to 8 electrons. This shell has 2 sublevels: 2s and 2p, each with a maximum capacity of 2 and 6 electrons, respectively.

Short Answer:

The human body (and most other objects) is (are) normally neutral and that means the number of protons is very nearly equal to the number of protons. There will be a few more electron or a few less at any given time based on interactions of the body (or object) with its enviroment, but unless there is a specific process that adds or subtracts a substantial number of electron, the body (the object) will be almost neutral. While it is true that the body is a complex system of electrolytes with positive and negative ions, they balance and the body is still nearly neutral.

Another Answer:

In all neutral atoms, the number of protons and electrons are equal. When atoms form compounds, they transfer electrons to and from one another, but the total amount of electrons remains the same. If you _did_ have many more protons or electrons, your body would become electrically charged (negatively for an excess of electrons, and positively for an excess of protons). This is indeed what happens when you run your feet through a rug and get a static charge, making your hair stand up and causing you to spark on a doorknob. But normally, the amount of protons and electrons are the same.

In the electron transport chain Oxygen is the final electron acceptor. Also the Oxygen accepts 2 Hydrogen ions, making water in the process. The dissapearance of Oxygen shows that the electron transport chain is working and that Oxygen is doing its job.

The final acceptor of electrons in the electron transport system of respiration is oxygen. Oxygen receives the electrons and combines with protons to form water during the process of oxidative phosphorylation in the mitochondria.

There are different electron configurations for gold because gold is a transition metal.

The standard (noble gas) electron configuration is : [Xe] 4f14 5d10 6s1

The electron configuration for gold, or Au begins with the base state of [Xe]. The outer shell is then 6s1 4f14 5d10.

Einsteinium has the atomic number of 99. Thus, it has 99 protons and, to keep it neutral, 99 electrons. Filling in the first 99 electron orbitals gives us the electron configuration of 1s2 2s2 2p6 3s2 3p6 4s2 3d10 4p6 5s2 4d10 5p6 6s2 4f14 5d10 6p6 7s2 5f11.

The external level of electrons in actinium has 2 electrons; but actinium is trivalent.

Magnesium's atomic number is 12. Therefore, it has 12 protons and 12 electrons. Filling in the first 12 atomic orbitals gives us the configuration of 1s2 2s2 2p6 3s2.
