How does the atomic number of an element compare with the number of electrons that normally surround the nucleus?
If the atom is atomically neutral (meaning that it does not hold a charge and it's not a cation or an anion), then the number of electrons and protons in an atom will be the same. If they do hold a charge (say if it is an anion), then it would have an extra electron. If it was positively charged, then an electron would be lost.

What is the symbol for one element that DOES NOT need eight electrons to have full set of valence electrons?
An element that does not require eight electrons for a full set of valence electrons is represented by the element symbol B. Boron only needs six electrons to complete its valence shell and achieve stability.
Select the answer that correctly indicates the number of protons and electrons for this atom or ion Sulfide ion?
The sulfide ion (S²⁻) has 16 protons and 18 electrons. This is because the element sulfur (S) normally has 16 protons and 16 electrons, but by gaining two extra electrons to achieve a stable electron configuration, it becomes the sulfide ion with 18 electrons.
What element has 4 protons 4 neutrons and 3 electrons?
Beryllium To figure this out: The atomic number of an element is the number of protons the element has in the nucleus. Using this knowledge you can figure out which element has the atomic number of four, which in this case is Beryllium.
How many valence electrons are in the element Neon?
There are 8 valence electrons in the element Neon, as it is in group 18 of the periodic table.
Which element has a mass number of 40 and only has 2 valance electrons?
The element that has a mass number of and two valence electrons is an isotope of calcium.
What element normally has 10 electrons?
Neon, (Ne)
How do the number of electrons compare in two isotopes in an element?
In a neutral atom, the number of electrons equals the number of protons. Isotopes of the same element also have the same number of electrons and the electronic structure.
What element forms a 3 plus ion with ten electrons?
The element that forms a 3+ ion with ten electrons is sodium (Na). Sodium has 11 protons and normally has 11 electrons, but when it loses 3 electrons to form a 3+ ion, it has a total of 10 electrons.
How many electrons are in the nucleus of the atom of polominium?
Polonium's atomic number is 84. That means it has 84 protons and 84 electrons. However, none of these electrons are found in the nucleus, but rather outside of it in what is called the electron cloud.
What element has 51 protons and 52 electrons?
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
What is atomic strucutre?
IT is the electrons on element IT is the electrons on element
Does an electron determine what element it is?
The number of protons determine which element an atom is and normally the number of electrons is equal to it. Strip an electron off an iron atom and you have an ionised iron atom.
How do you hook up surround sound to element tv?
I tried to do this and there is no way you can have surround sound on that tv.
What elements contains 66 electrons?
Dysprosium has atomic number 66 so would normally have 66 electrons.
How many electrons does the element neon?
The Element Neon has 10 protons and 10 electrons.
Is NO nonpolar?
NO is polar. If you compare the electronegativities (how strongly the element pulls on electrons) N 3.04 O 3.44 ( bigger therefore pulls electrons harder) The electrons will be drawn to the oxygen causing it to be slightly negative, and the N to be slightly positive.
How many electrons does Ni 3 plus have?
Nickel is a chemical metal element. There are 28 electrons in a single atom.
