There are 2.
Count the electrons in the s and p orbitals of that shell. Since Cd is in the shell n=5, there are 2 electrons in the s orbital and 0 in the p orbital.
Cadmium (Cd) has 2 electrons in the 4s orbital and 10 electrons in the 4d orbital, giving it a total of 12 valence electrons.
The number of valence electrons in cadmium ion 48, while that of neutrons is 66.

What is the number of valence electrons in cadmium Cd?
The number of valence electrons in cadmium (Cd) is 2. Cadmium is in Group 12 of the periodic table, so it has 2 valence electrons.
How many core electrons are in Cd?
Cadmium (Cd) has 48 electrons, and its electron configuration is [Kr] 4d10 5s2. This means that the core electrons in cadmium are those in the inner shells, which are the 36 electrons from the noble gas krypton (Kr). Therefore, cadmium has 36 core electrons.
How do you draw the electron dot diagram for cadmium?
First, write Ca on the paper. Next, look at the periodic table to find the number of valence electrons. You will see the electron configuration is 2-8-8-2. Therefore, it has 2 valence electrons. Draw two dots around the Ca to form the diagram.
How many 5s electrons are in Cd?
Cadmium (Cd) has 48 electrons in total. It has configurations of 2, 8, 18, 18 and 2 electrons in its electron shells. This means that cadmium has 2 electrons in its 5s orbital.
Which of the following is paramagnetic Se Cd Ar He Ca?
Se and Cd are paramagnetic because they have unpaired electrons, while Ar, He, and Ca are diamagnetic because all their electrons are paired.

Why do group 12 elements have different properties that group 13?
The group 12 elements have an electronic configuration of nd10(n+1)s2. The group 13 elements have the configuration of nd10(n+1)s2(n+1)p1. The group 12 elemnts Zn, Cd and Mercury have only 2 valence electrons, (s electrons). Group 13 elemnts B, Al, Ga, In Tl have 3 valence electrons, s2 p1. The chemistry of the groups is therefor different.
Which species has 48 electrons?
The element with 48 electrons is cadmium (Cd). Cadmium is located in the periodic table with atomic number 48.
How do you get a dust cloth on Howrse?
This is due to static electricity. When you wipe a CD surface (plastic) with a cloth, it rubs extra off extra electrons onto the CD's surface, thus imparting a negative static charge to the CD.
What 2 alkali metals have only 1 valence electron?
There are actually three transition metals with only one ionic charge.The three are...Silver(Ag) plus one chargeCadmium (Cd) plus two chargeZinc (Zn) plus two charge
Which changes occur as a cadmium atom Cd Becomes a cadmium ion Cd 2?
When a cadmium atom becomes a cadmium ion, it loses two electrons to achieve a stable electron configuration. This loss of electrons changes the charge of the cadmium atom from neutral to a 2+ charge, resulting in the formation of a positively charged ion.
Why is Mercury a liquid at room temperature?
A solid melts when the available energy in heat exceeds the energy required to break up the solid, which is equal to the extra energy gained by letting the atoms stay always close to one another rather than passing only occasionally near like ships in the night. The simplest model of metals treats the valence electrons as a gas around charged cores composed of the atoms minus their valence electrons. Zn, Cd and Hg all have the same number of valence electrons (2) and hence the same charge on their cores, *but* the volume each valence electron has to move around in increases from 8 to 11 to 12 in units of 10^-24 cm^3, that is the gas of valence electrons becomes less dense. When it is less dense, the electrons interact (favorably) with the oppositely charged cores less often, so the extra energy gained by having cores and electrons all close together is less, hence the extra energy of the solid is less, hence the melting point lower. Why should the valence electron gas get less dense? Not an easy question to answer, the density is a delicate competition between the desire of all the electrons to get close to the cores and their mutual repulsion. Since the Hg core is bigger (it has more non-valence electrons in it) the electrons are squeezed anyway in Hg by the core hogging more space, so you might guess the preferred density might end up a little lower, as it does. This is simply because Mercury has a very low melting point (-38.83°C/234.32K), meaning it is only a solid when it gets cold enough.
What is the charge of a Cadmium atom with 48 electrons?
Cadmium (Cd) has an atomic number of 48, which means it has 48 protons and is neutral when it has an equal number of electrons. Therefore, a cadmium atom with 48 electrons would have a charge of 0 or be electrically neutral.
