The number of protons, neutrons and electrons for each atom increases as you go down a group. Hydrogen is the lightest element as it has the fewest sub-atomic particles.

What is periodic in the periodic table?

The modern periodic table is modified form of the mossleys periodic table,which was yet modifiied form of the mendileevs periodic table,which was based on the principle-atomic mass is the periodic function of the elements.Mossley changed the periodicity of elements to be the periodic functions of their atomic numbers.hence in the modern periodic table we can find,the repeatation of certain properties of elements after definite intervals and hence the periodic table has groups and periods the elements inside which,are similar.this is possible because across a period electrons increase by 1,keeping shells sama,and down a group,outer electrons remain same,but shells increase by1.


What American psychologist created a periodic table of the elements of consciousness?

William James, an American psychologist, is known for developing a periodic table of the elements of consciousness. He believed that consciousness could be broken down into basic elements similar to how chemical elements are organized in the periodic table.


When you go down the periodic table what happens to the electronegativity?

Increase -tac


How was mendeleevs periodic table like todays periodic table?

Mendeleev's periodic table arranged elements by increasing atomic mass and grouped elements with similar properties together. Today's periodic table is similar, but it is arranged by increasing atomic number, which reflects the number of protons in an atom's nucleus. Both tables also show periodic trends in properties as you move across and down the table.


Which periatic table cannot be broken down into simpler substance?

The periodic table itself cannot be broken down into simpler substances because it is a tabular arrangement of all the known chemical elements. Each element on the periodic table is a fundamental substance that cannot be further broken down into simpler substances by ordinary chemical processes.

Do elements on the periodic table increase in electronegitivity as you go left to right or up and down?

Electronegativity increases as we move from left to right on the periodic table.


Which way does electron shells increase on the periodic table?

The number of shells in periodic table increase down the group, i.e., vertically.


Why do elements increase in size as you move down the periodic table?

Down the group, atomic radius increases. This is due to increase in number of shells.


How are the size of the elements effected on the periodic table?

Atomic size increase down the group and decreases across the period.

Does shielding increase as you move down a group in the periodic table?

Yes, shielding increases as you move down a group in the periodic table.


What happens to the radii of the elements between 2 highest peaks?

The radii of elements generally decrease as you move from left to right across a period in the periodic table. The radii then increase as you move down a group in the periodic table. This trend is due to changes in the atomic structure of the elements.

Are compounds listed in the periodic table?

No, compounds are not listed in the periodic table. The periodic table lists elements, which are substances that cannot be broken down into simpler substances by chemical means. Compounds are formed when elements combine chemically in specific ratios.
