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.

How many core electrons are in Cd?
Oxygen as 2 core electrons and 6 valence electrons.
What is the number of valence electrons in cadmium Cd?
2. The elctron configuratio of Cd is [Kr] 4d10 5s2
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.
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.
Which changes occur as a cadmium atom Cd Becomes a cadmium ion Cd 2?
the cadmium atom looses two electrons and its radius decreases because by taking away two electrons (negatively charged) it makes the nucleus positive with a positive 2 charge. since theres two less electrons the radius is smaller. hope i helped :D

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.
Which of the following is paramagnetic Se Cd Ar He Ca?
Se is paramagnetic because it has unpaired electrons
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
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.
Which species has 48 electrons?
Cadmium is the only neutral atom (not electrically charged) to have 48 electrons.
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.
What is the charge on the cadmium ion in Cd3PO4 2?
Cadmium is a divalent metal with the cation Cd+.
