Because they have a different number of electrons.
Platinum is typically separated from other metals using a process called chemical precipitation or smelting. These methods involve using chemical reactions or high temperatures to extract pure platinum from its ore or alloy.
A correct Bohr model of platinum shows the nucleus at the center, surrounded by electron shells. Platinum has 78 electrons arranged in energy levels/shells of 2, 8, 18, 32, 17, 1, with the last electron in the outermost shell. The Bohr model helps visualize the electronic configuration and the distribution of electrons in an atom.
The electron configuration of Platinum is: 1s2 2s2p6 3s2p6d10 4s2p6d10f14 5s2p6d9 6s1
Some examples of platinum include platinum jewelry, platinum catalysts used in chemical reactions, and platinum electrodes in certain electronic devices. Platinum is also used in the automotive industry for catalytic converters.

Platinum has multiple energy levels, due to its 78 electrons distributed in different orbitals and subshells within its electronic configuration. The specific number of energy levels depends on how its electrons are positioned within the atom, following the rules of quantum mechanics.

14k Gold Over Dental Gold. Dental gold is between 10K and 20K, frequently 16K. To make it hard enough for dental purposes, the other alloys are often platinum or paladium.
The electronic configuration by shell for the element Platinum is the same as the filled shells of Xenon (q.v.), plus the following added: 14 electrons in the 4f shell, 9 in the 5d shell, and one in the 6s. Note that protons do not occupy shells in the atom but are bound in the nucleus.
The electron configuration of platinum is [Xe]4f14.5d9.6s1.
Platinum typically forms a Pt2+ ion. This means that platinum has lost two electrons to achieve a more stable electron configuration.
