A transition element of f-block Thorium has 90 electrons in natural state, it is a Radioactive element.
The element Neon
Elements on the periodic table are arranged according to the number of protons in their nucleus, also known as their atomic number.54th element on the periodic table is Xenon.
The element with the atomic number 85 is Astatine (At). Astatine is a Radioactive Halogen in Group 17(7) of the Periodic Table. Astatine has 85 electrons in 6 shells with 7 electrons in the outer shell. Astatine is the third radioactive element on the Periodic Table.
it is the very common atom Carbon. --- The element could be carbon, if the four electrons are in the valence shell. However, if it is total of four electrons, then the element will be beryllium
Chlorine has 17 electrons. It is displayed as atomic number in periodic table.
Neptunium is element 93.
Curium
Berkelium
Californium (Cf).
There is none, but a neutral atom is called a neutron. There is no neutral element.
Element 95 is americium.
The element Neon
To determine the number of valence electrons, you look at the group number of an element on the periodic table.
The atomic number on the periodic table is the number of protons for the element.
Helium
Nitrogen is the 7th element in the Periodic Table. It has 7 electrons and protons.
The charge of an ion formed by an element on the periodic table is determined by the number of electrons gained or lost by the element. This charge can be positive or negative, depending on whether the element loses or gains electrons.
