The electronic configuration by shell for the element Platinum is the same as the filled shells of Xenon (q.v.), plus the following added: 14 electrons in the 4f shell, 9 in the 5d shell, and one in the 6s. Note that protons do not occupy shells in the atom but are bound in the nucleus.
What else can I help you with?
How many electrons are in platinum?
When it has no charge there are 78.the number of electrons is always equal to the number of protons, both are the atomic number. the atomic number of platinum is 78, so 78 electrons and 78 protons too.
How many protons are on the first shell of an atom?
The first shell of an atom can hold a maximum of 2 electrons. Since the number of protons in an atom is equal to the number of electrons in a neutral atom, there can be a maximum of 2 protons in the first shell.
How many of protons and electrons in each shell of sulfur?
firstly the protons are in the nucleus of an atom. there are 16 protons there. the number of electrons is the same as the number of protons. the electron arrangement is as follows: first shell-2 electrons second shell - 8 electrons third shell - 6 electrons this can also be written as 2,8,6
If an element has 9 electrons how many should be in the second shell?
There should be seven in the second shell and two in the first. The element in question is fluorine, which has the atomic number 9, the same as the number of its protons and electrons.
How many electrons does beryllium have in all?
Beryllium typically has 4 electrons in total. It has 2 electrons in its inner shell and 2 electrons in its outer shell.
How many protons belong in each shell of a diagram for the element seaborgium?
Seaborgium has 106 protons; shellls, diagrams are related to electrons.
What does the atomic number tell you besides the number of protons in one atom of an element?
The atomic number also tells you the number of electrons in a neutral atom of the element. Additionally, it determines the position of the element in the periodic table and helps to identify the element uniquely based on its number of protons.
How many electrons fill the outer shell of helium?
There is only one electron inhabiting hydrogen and the compound therefore only has one shell, effectively making that shell the outer shell. TL;DR There is 1 electron in the outer shell of hydrogen.
What element has 2 electrons in the first shell 8 second shell and 6 in the third shell?
This element is sulfur (S), with 2 electrons in the first shell, 8 electrons in the second shell, and 6 electrons in the third shell.
How many protons neutrons and electrons does a ununseptium shell?
Unundeptium has 117 protons and electrons; the number of neutrons is 176 or 177, depending on the isotope.
Is an element's reactivity determined by the number of protons found in an atom of an element?
No, an element's reactivity is mainly determined by the number of electrons in its outer shell, known as valence electrons. Elements with fewer valence electrons tend to be more reactive as they seek to either lose, gain, or share electrons to achieve a stable electron configuration. The number of protons in an atom, which determines the element's identity, does not directly influence its reactivity.
Which element has 4 valence electrons in the 6th shell?
The element with 4 valence electrons in the 6th shell is lead (Pb). Lead has 4 electrons in its outermost shell, which is the 6th electron shell.
