What does elements symbol consist of?
A periodic table is a chart with all of the elements and their symbols, their atomic numbers and atomic masses. Good ones will also have the name of the element to make finding them easier.
Why is the periodic table is so useful?
It helps people find elements on the periodic table.yes that and more it also tells you the atomic number and mass of those elements
What determines the way elements are ordered?
The way elements are ordered in the periodic table is based on their atomic number, which represents the number of protons in the nucleus of an atom. Elements are arranged in increasing order of atomic number from left to right across periods and top to bottom within groups. This arrangement helps group elements with similar properties and trends, making it easier to understand their behavior.
Why did mendeleev organize the periodic table according to mass?
Back in Mendeleev's time (late 1800's), scientists knew nothing at all about quantum mechanics and the structure of the atom. Therefore, they didn't know about how each element is different by 1 proton as we go across a period. Instead, Mendeleev arranged the elements by atomic weight- which could be done using scales and mathematics. His predictions were largely accurate- and it's his version of the table that makes up the modern form today.
Describe the Reactivity of group 1 element varies with increasing atomic number?
The reactivity of Group 1 elements increases with increasing atomic number. This is due to the fact that as atomic number increases, the outermost electron is farther away from the nucleus, making it easier to lose and therefore more reactive. Additionally, the size of the atom increases down the group, leading to a weaker attraction between the outermost electron and the nucleus, further enhancing reactivity.
Why are the elements at the bottom of the series discovered before the elements on the top?
Elements at the bottom of the periodic table were discovered later because they have higher atomic numbers, indicating they have more protons in their nucleus. Historically, elements with lower atomic numbers were easier to study and discover due to their simpler properties and availability in nature. As technology advanced, scientists were able to synthesize and discover elements with higher atomic numbers, leading to the discovery of elements at the bottom of the periodic table.
Why do elements of even atomic numbers are more abundant than that of odd numbers?
Elements with even atomic numbers are more abundant than those with odd atomic numbers because of nuclear stability. Elements with even atomic numbers have equal numbers of protons and neutrons, resulting in more stable nuclei due to pairing effects. This stability makes it easier for elements with even atomic numbers to be formed through various nuclear processes, leading to their higher abundance compared to elements with odd atomic numbers.

What is period used for?
To find the information on certain elements!!Periodic Table lists elements in the increasing order of atomic number.Since elements are grouped in to columns (eg:inert gases), it is easier to predict the chemical behaviour of various elements.

Is a periodic table an easier way to organize the elements?
Yes by far. It has many patterns and is organized by the atomic number or the number of protons and electrons.
Why did Dmitri make the periodic table?
Dmitri Mendeleev arranged the elements known at that time in the increasing order of atomic masses and repeating properties, so that it is easier to classify and study the properties of the elements.
What is the difference between the new and old periodic table?
Well, Back when Medeleev made this table, many of the elements were not even discovered yet. He plotted only the elements that he knew on his table. He organized them by increasing atomic weight. He didn't know all the elements so he would put question marks and empty spaces in the spots he thought elements would be and left to be found by other scientist. He happened to be true about the missing elements and that scientist did end up finding these "missing links" of the periodic table and led to the new or modern periodic table. The modern periodic table doesnt have any missing elements and they changed Medeleev's way of organizing the table by increasing atomic weight to increasing atomic number. So the newer form of the periodic table was complete and made it easier to find what elements react better with other elements. This making the modern table became the more efficent table of our time.

Why do youthink the elements are arrange the way that they are?
On the Periodic Table of Elements, the order from top left to bottom right is determined by the atomic number of that element, which is determined by the number of protons that are present in the nucleus of that element's atom.
