What are electrons on a periodic table?
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
Why are the elements different colors?
Elements have different colors primarily due to the way they absorb and emit light, which is influenced by their atomic structure. When light interacts with an element, electrons can absorb specific wavelengths of light, causing them to jump to higher energy levels. When these electrons return to their original state, they release energy in the form of light, which corresponds to particular colors. Additionally, factors like the arrangement of atoms and the presence of impurities can also affect the color observed in elements.
What is it about their atomic structure that enables elements to conduct electricity?
Elements that conduct electricity typically have free electrons in their outer atomic structure. These free electrons are able to move easily through the material, creating an electric current. Metallic elements are good conductors of electricity because they have loosely held outer electrons that are free to move.
What is the atomic number and number of valence electrons for each nucleic acid elements?
For carbon (C): Atomic number 6, 4 valence electrons. For hydrogen (H): Atomic number 1, 1 valence electron. For nitrogen (N): Atomic number 7, 5 valence electrons. For oxygen (O): Atomic number 8, 6 valence electrons. For phosphorus (P): Atomic number 15, 5 valence electrons.
What determines a transition metal's hardness and boiling points?
A transition metal's hardness and boiling points are primarily influenced by the strength of the metallic bonds, which arise from the delocalization of d-electrons. The presence of strong covalent interactions in the metal's crystal structure also contributes to hardness. Additionally, factors such as atomic size, lattice structure, and the presence of impurities or alloying elements can significantly affect these properties. Generally, transition metals with higher atomic numbers and more d-electrons tend to exhibit greater hardness and higher boiling points.

What properties did Mendeleev position the elements on the table?
Mendeleev created his Periodic Table at the time when presence of sub-atomic particles like electrons, protons and neutrons were not discovered.So, the term atomic number was not known till now. So , he positioned the elements in increasing order of atomic mass because Atomic Mass of many elements discovered till then were known.

What effect does the nucleus have on atomic spectra of different elements?
The nucleus of an atom does not directly affect the atomic spectra of different elements. The atomic spectra are mainly a result of the electron configuration and transitions in the electron energy levels. However, the nucleus can indirectly influence the spectra through its impact on the arrangement and energy levels of the electrons.
How are the elements in a period different?
By their atomic weight..protons and electrons.
How do you find electrons in elements on the periodic table?
The number of electrons are equal to the number of protons which is equal to the atomic number. That's if you're trying to find the number of total electrons. If you want to find the number of valence electrons (electrons in the outermost shell) you must look at the group numbers. The group number is equivalent to the number of valence electrons.
