What is the most important factor in an elements place in the periodic table?
Its elemental weight
How many electrons are needed to complete outer shell of hydrogen?
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
How many electrons will arsenic gain to have a filled outer shell?
Arsenic, with an atomic number of 33, will gain 3 electrons to have a filled outer shell, achieving stability with 8 electrons in its outer shell like a noble gas.
Is the atomic number of oxygen 8 because oxygen has a second shell with 8 electrons?
The atomic number of an element is the number of protons in its nucleus, which determines its chemical properties. Oxygen has an atomic number of 8 because it has 8 protons. The electrons in the outer shells of an atom can vary, but the number of protons remains constant.
How many electrons in the outer shell does hydrogen ion have?
no electron is present in the outer most shell of hydrogen ion
How many electrons does o element have?
The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
What is the atomic number of helium's outer shell?
The outer shell of helium does not have an atomic number, that number belongs to helium itself whose atomic number is 2.

Its elemental weight
How many electrons are present in the outer shell of an atom with an atomic number of 14 and an atomic weight of 29?
Atomic number is the number of protons. In a neutral atom, the number of protons is equal to the number of electrons. So, in your example, the number of electrons in this atom is 14. The first energy shell can take 2 electrons, the second energy shell can take 8 electrons, and the third energy shell can take 18 electrons. If there are 14 total electrons, 10 would be found in the first two energy shells, leaving 4 for the third energy shell.
How many electrons are needed to complete outer shell of hydrogen?
Hydrogen is group 1 family, which is Alkali metals. Therefore, Hydrogen has 1 electron in its outermost shell. This means, it will perform +1 ion when they react. === ===
How many electrons nitrogen has in its outer energy levels?
Nitrogen has atomic number = 7. The outer shell has 5 electrons, it requires 3 more electrons to complete the outer energy shell.
What is the factor that affects the atomic number in an element?
More shielding of the outer electrons by the inner electrons is the most important factor that affects the atomic number in an element. A valence electron in an atom is attracted to the nucleus of an atom and is repelled by the other electrons in the atom. The inner electrons shield the outer electrons from the attraction of the nucleus and cause the atomic radius to be larger.
How many unpaired electrons are in a sulfur atom (atomic number 16)?
There are six unpaired electrons in a sulfur atom (atomic number 16) because sulfur has six valence electrons in its outer shell.
How many does hydrogen electrons in the outer shells?
Hydrogen has only one valence electrons.
Does helium have a complete outer shell?
Not by itself, no (that is, hydrogen is not a noble gas). A neutral hydrogen atom starts out with 1 electron, but it needs 2 electrons to fill its shell. Therefore, a hydrogen atom will often form 1 covalent bond with another atom, in order to gain that 1 extra electron it needs to fill its shell. Important note: Most elements need 8 electrons to get a full shell, but hydrogen is the exception: it only needs 2 electrons to get a full shell.
Where do electrons collect?
Electrons collect in the outer energy levels of atoms, known as electron shells. These shells are organized around the atomic nucleus and can hold a specific number of electrons based on the atom's atomic number and electron configuration.
How many electrons will arsenic gain to have a filled outer shell?
Arsenic, with an atomic number of 33, will gain 3 electrons to have a filled outer shell, achieving stability with 8 electrons in its outer shell like a noble gas.
