A chloride ion has the same number of electrons as a neutral atom of an element in Period 3 of the periodic table, as both consist of 17 electrons.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of chlorine (Cl). The neutral chlorine atom has 17 electrons, and when it gains one electron to form the chloride ion, it also has 17 electrons but with a 1- charge.
Do you mean what does the number of protons equal? This is the atomic number of the element. All isotopes of an element will have the same number of protons, only the number of neutrons varies.
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.
The number of electrons is equal to the number of protons which determines it's atomic number. Therefore, the element with 3 electrons is the one with 3 protons which has an atomic number of three which is Lithium (symbol - Li, amu - 6.941)
A chloride ion has the same number of electrons as a neutral atom of an element in Period 3 of the periodic table, as both consist of 17 electrons.
There is none, but a neutral atom is called a neutron. There is no neutral element.
Element X with 72 protons will have 72 electrons in a neutral state. The number of protons in an element is equal to the number of electrons in that element's neutral atom.
You can only be sure of the number of electrons if the element is electrically neutral. If an element is electrically neutral, then the number of electrons is the same as the number of protons which is the atomic number of the element. For instance an electrically neutral atom of carbon, there are 6 electrons because there are 6 protons in a carbon atom.
Yes, in a neutral atom the number of electrons and protons is equal, and it is the number of protons that determines what element the atom is. So, by looking at the number of electrons you can tell what element it is.
A chloride ion (Cl-) has the same number of electrons as a neutral atom of chlorine (Cl). The neutral chlorine atom has 17 electrons, and when it gains one electron to form the chloride ion, it also has 17 electrons but with a 1- charge.
no . by the number of protons which determines the number of electrons when neutral
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
Yes, this is true for electrons (and protons) of all neutral atoms of an element.
The atomic number of an element can be used to determine the number of electrons in an atom. It is equal to the number of protons in the nucleus of an atom, which also corresponds to the number of electrons in a neutral atom.
An element's' atomic number, and in a neutral atom the number of its electrons.
A neutral atom of an element will have the same number of electrons as protons (atomic number). For example, the element magnesium has the atomic number 12, which means that a neutral magnesium atom will have 12 protons and 12 electrons.
