A Period
arsenic belongs to V-A group of periodic table it has 5 electrons in its outermost energy level.
The period tells you how many energy levels an atom has.
the principal energy levels of valence electrons increase.
It has 2 unpaired electrons and 8 empty electron levels.
electrons
that depends on the number of electrons the more electrons the more energy
As more energy levels are occupied by electrons, the atomic radius gets larger.
The more energy levels that are occupied by electrons, the larger the atomic radius.
the period number tells which is the highest energy level occupied by the electrons
the period number tells which is the highest energy level occupied by the electrons
Electrons occupied certain discrete energy levels around the nucleus.
Electrons occupied certain discrete energy levels around the nucleus.
Electrons occupied certain discrete energy levels around the nucleus.
A Period
i don't the answer
The period number tell about the energy levels occupied by electrons
