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.
What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
How does atomic mass indicated element reactivity?
Atomic mass does not directly indicate an element's reactivity. Reactivity is primarily determined by the number of electrons in the outer shell of an element (valence electrons). Elements with a full or nearly full outer shell (noble gases) are generally unreactive, while elements with few electrons in the outer shell (alkali metals) are highly reactive.
How many electrons does he have in outer shell?
To determine the number of electrons in the outer shell of an atom, you need to know its atomic number or its position in the periodic table. The outer shell electrons are also known as valence electrons, and their number varies depending on the element. For example, elements in Group 1 have 1 valence electron, while those in Group 18 have 8 valence electrons (except for helium, which has 2). If you specify the element or atom in question, I can provide the exact number of outer shell electrons.
What is the total electrons in outer shell of uranium?
The total number of electrons in the outer shell of uranium is 2 electrons. Uranium has an atomic number of 92, which means it has 92 electrons. The electron configuration for uranium is [Rn] 5f3 6d1 7s2, so the electrons in the outermost shell are the 7s2 electrons.
What is the atomic number of hydrogen and the number of its electrons in the outer shell?
The atomic number for hydrogen (H) is 1, and it has 1 electron in the outer shell.
How many electrons are present in the outer shell of an atom with an atomic number of 14 and an atomic weight of 29?

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.
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.
How many electron are on the outer shell of a manganese?
Manganese, with an atomic number of 25, has 2 electrons in its first shell, 8 in its second, 13 in its third, and 2 in its fourth outer shell. So, there are 2 electrons in the outer shell of a manganese atom.
What is the number of electrons to fill the outer shell of nitrogen?
As Nitrogen (N) have atomic number 7, and electronic configuration is 2,5. therefore N required 3 elecrons to complete their outermost shell or orbital.
How many electrons would the atomic structure of Tin have on its outer shell?
There are four electrons found on the outer shell of a atomic structure of tin. They are in a group of four.
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.
What is heliums number of valence electrons?
Helium has 2 valence electrons. Being in Group 18 of the periodic table, helium is a noble gas and has a full outer electron shell.
How many electrons does nitrogen require to fill its outer shell?
Its atomic number is 7, and so it needs a further 3 electrons to fill its outer shell.
Why is chlorine in period 3?
Chlorine is in period three because that is how many outer shells it has. One period is one shell... In the First outer shell you can only hold.. 2 electrons. Second outer shell can hold 10 electrons. Third outer shell can hold 18 electron. Protons + Electrons = Atomic Number Atomic Number - Atomic Mass = Number of Neutrons in Outer Shells
How many electrons would you expect chlorine with an atomic number of 17 to have in its outer shell?
Chlorine has 17 electrons, distributed in the following way: 2 in first shell 8 in second shell 7 in third (outer) shell Therefore Chlorine has 7 electrons in its outer shell.
