across a periodic table, the properties of elements become less metallic and more nonmetallic
The arrangement of elements on the periodic table reflects their atomic structure and properties, with elements grouped by similar chemical behaviors and characteristics. This organization reveals periodic trends, such as electronegativity, atomic radius, and ionization energy, which vary systematically across periods and groups. As you move from left to right, elements typically become less metallic and more non-metallic, with increasing electronegativity. Therefore, the periodic table serves as a valuable tool for predicting and understanding the chemical properties of elements based on their positions.
No, elements become less metallic across periods. Periods are horizontal rows within the periodic table, and read left to right. The far right elements are called non-metals, and the far left elements are called metals. In between these two groups are a few metalloids - elements that have characteristics of both metals and non-metals. A period looks like this: Metals --> Metalloid --> Non-metals
After an initial publication in 1869, Mendeleev published the first comprehensive periodic table in 1871. He started using it almost immediately to• Rationalize the properties of elements• Guide approaches to the synthesis of new compounds• Predict the properties of the elements where he had had to leave gaps in his periodic table
The physical and chemical properties of elements change in a systematic way across the periodic table, primarily due to variations in atomic structure, such as electron configuration and atomic size. As you move from left to right across a period, elements generally become less metallic and more non-metallic, with increasing electronegativity and ionization energy. Conversely, moving down a group, elements tend to exhibit increasing metallic character, larger atomic radii, and decreased ionization energy. These trends arise from the influence of nuclear charge and the shielding effect of inner electrons.
The periods in the periodic table indicate the energy levels of the electrons in an atom. Elements in the same period have the same number of electron shells, which influences their chemical properties and reactivity. As you move from left to right across a period, the atomic number increases, and elements typically become less metallic and more non-metallic. This trend affects their electronegativity, ionization energy, and overall behavior in chemical reactions.

in groups, as we go down metallic characteristics increases but in periods as we go left to right metallic characters decreases because non-metals are being introduced. i hope it helped!

they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
Periodic trends illustrate how some elements are very reactive while others are stable.
they become more reactive since you are moving from left to right on the Periodic Table, the elements in group 17 are the most reactive.
element in a group exibhit more or less same properties some of them have more things and some have less as they are dependent on the valency in the outermst shell of the elctrons so that they acn become reactive ,metal non metals etc
In a period of the periodic table, elements have the same number of electron shells but different numbers of electrons in their outer shell. As you move across a period from left to right, the number of protons and electrons increases, causing elements to become more electronegative and decrease in atomic radius. Additionally, elements within a period show a trend of increasing metallic to non-metallic properties.
They become more stable.
