How many electrons are in the outer shell of an atom with the atomic number 30?
W0nderw0man1979
one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1 one, it's K, or potassium fill your shells (orbitals, really) in order until you get to 19 electrons K 2-8-8-1

The tendency of an element to react chemically is closely related to what?
its Atomic Mass.
If carbon has four electrons in its outer shell does it completely fill its outer selectron shell?
Yes. Two of the electrons will go into the carbon's outer s shell (2s) to completely fill it (s orbitals can contain up to two electrons) and the remaining two will go into its outer p shell (2p).
What does a drawing of the atomic model for chlorine look like?
An atomic model of chlorine has three electron shells surrounding its nucleus. The first shell has 2 electrons. It has the least amount of kinetic energy among the three shells. The second shell has 8 electrons and has less kinetic energy than the outer shell, but more kinetic energy than the inner shell. The third shell has 7 electrons. It has the highest kinetic energy level of the three shells.
What do elements with in a family tend to share?
similar chemical properties and characteristics
What determines the chemical activity of an atom?
The nucleus of an atom (protons and neutrons) determines if an atom is radioactive. The tendency is, the larger the nucleus, the more unstable it is and the more likely it is to be radioactive. As for the chemical bonding properties of the atom, the electron configuration determines how it will bond, with what it will bond, and in what ratio atoms will bond to form the 20,000,000 different substances on Earth.
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.
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 does chlorine have in it's outer shell?
Chlorine has 7 electrons in its outer shell. It needs one more electron to achieve a full outer shell of 8 electrons, which is why chlorine typically gains an electron to form Cl- ion in chemical reactions.
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 does nitrogen require to fill its outer shell?
Nitrogen requires 3 electrons to fill its outer shell. This allows it to achieve a stable configuration similar to a noble gas.
The elements within a group have a similar number of?
Elements in the same group have the same number of valence electrons. These are the outer-shell electrons that react with other elements.
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 the most important factor in an elements place in the periodic table?
Its elemental weight
How do you determine how reactive an element is based off its atomic number?
the reactivity of depends on the number of its outer shell electrons. one all outer shell electrons are there then there is little reactivity. If the atomic number is 19 then the element will 19 protons and 19 electrons. this means it has 2 electrons in the 1st shell 8 in the second 8 in the 3rd and 1 in the last. as it only has one it will be very reactive =)
What is the atomic number of helium's outer shell?
The atomic number of helium is 2, which means it has 2 electrons in its outer shell. Helium has a full outer shell, making it a stable and inert element.
Does argon has the same number of electrons in its outer shell as magnesium metal?
No. Argon has eight electrons in its outer shell and magnesium has two electrons in its outer shell.
