Scandium is a chemical element with atomic number 21 which means there are 21 protons in its nucleus. Total number of protons in the nucleus is called the atomic number of the atom and is given the symbol Z. The total electrical charge of the nucleus is therefore +Ze, where e (elementary charge) equals to 1,602 x 10-19 coulombs.

As you move across an element period (row), the overall size of atoms decreases slightly. Even though atoms further to the right have more protons, neutrons, and electrons, the outer electron shell is the same. The increased number of protons exerts a stronger positive charge, pulling the electrons in toward the nucleus. This special …

Transition metals are defined as those elements that have (or readily form) partially filled d orbitals. As shown in Figure 23.1.2 23.1. 2, the d-block elements in groups 3–11 are transition elements. The f-block elements, also called inner transition metals (the lanthanides and actinides), also meet this criterion because the d orbital is ...

The two elements following argon in the periodic table are potassium, with a single 4s electron, and calcium, with two 4s electrons. Because of the presence of the 4 s electrons, the 3 d orbitals are less shielded than the 4 p orbitals; therefore, the first regular transition series begins at this point with the element scandium, which has the ...
