The chemical symbol of chlorine is Cl. Atomic number of it is 17. It has 17 electrons.
The symbol for xenon is Xe, and a neutral atom of xenon has 54 electrons.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
If an atom has 35 electrons, it will also have 35 protons and its atomic number will be 35. If you go to the periodic table an look up the element with atomic number 35 you will se it is the element Bromine and the symbol for the element is Br.
Chlorine has an atomic number of 17, which means it has 17 electrons. The symbol 35Cl tells us that chlorine has a mass number of 35, indicating it is a specific isotope of chlorine with its corresponding number of protons and neutrons.
Cl has 17I has 53 Xe has 54 and Sb has 51.
The chemical symbol of uranium is 'U' and it has 92 electrons.
The symbol of a boron atom is "B", and the number of electrons in a neutral atom is the same as the number of protons, which equals the atomic number of boron: 5.
The symbol for antimony is Sb. A neutral atom of antimony has 51 electrons.
The symbol for boron is B, and a neutral atom of boron has 5 electrons.
The symbol for xenon is Xe, and a neutral atom of xenon has 54 electrons.
The chemical symbol of uranium is U. Uranium has 92 electrons.
Electron configuration of uranium: [Rn]5f36d17s2
The symbol for the element with 5 electrons in its neutral state is B, which stands for Boron. Boron has an atomic number of 5, meaning it has 5 protons and 5 electrons when it is in its neutral state.
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
In set notation, the symbol for an element typically represents its atomic number, which corresponds to the number of protons in the nucleus of an atom. For neutral atoms, this atomic number also indicates the number of electrons, as they are equal in a neutral state. However, if the element is an ion, the number of electrons may differ from the number of protons, reflecting its positive or negative charge. Thus, the symbol alone does not convey the number of electrons if the atom is charged.
A carbon atom with the symbol 12C has 6 electrons since the atomic number of carbon is 6, indicating the number of protons and electrons in a neutral atom are the same.
The number of protons in a nucleus is called the atomic number, usually identified as the symbol Z. It defines the element in the Periodic Table. In a neutral atom, ie not ionised, there is an equal number of electrons
