How do you account for the general trend in atomic radius across a row of elements?
The general trend in atomic radius across a row of elements decreases from left to right due to increasing effective nuclear charge, which attracts the electrons closer to the nucleus. As you move across a period, the number of protons in the nucleus increases, resulting in a stronger pull on the electrons and a decrease in atomic radius. Additionally, the shielding effect of inner electrons remains relatively constant, further contributing to the trend.
What else can I help you with?
Which group of the main group elements contains the largest elements - Atomic Radius?
Group-1 has largest atomic radius. It decreases across a period
WHAT BEST STATES THE TREND IN ATOMIC RADIUS ACROSS THE PERIODIC TABLE?
As you move across the periodic table from left to right (across a period), the atomic radius of the elements tends to decrease.
What is the relevance of increasing atomic numbers in the arrangement of elements?
By doing it this way, you can arrange them in a fashion in which you can predict their reactivity by the row that they're in. This is because they are lined up to account for a visualisation of how much of the energy level is filled with electrons
What goes across the periodic table?
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons. The number of neutrons can vary with different isotopes of the same element, this means that atomic mass can vary with different isotopes. So atomic number does not vary, but atomic mass does, so it is more logical to use atomic number to organize the elements. In addition, when the elements are arranged according to atomic number into seven rows and 18 columns, it becomes evident that there are certain trends that occur across the periods, and that elements in the same group have similar properties.
Elements across a series have same number of?
Elements across a series have the same number of attributes or characteristics.
In general - what happens to the atomic radius from left to right across a period?
Generally, it decreases.*As you move from left to right across a period the elements' number of protons increases, increasing the effective nuclear charge (the charge felt by the outermost [valence] electrons after taking into account the shielding electrons). As effective nuclear charge increases the attraction between the nucleus and the valence electrons increases, pulling the valence electrons closer to the nucleus, decreasing the atomic radius.*Please understand that this is not a hard and fast rule. There are other factors to take into account when determining atomic radius, this is just a general trend witnessed.

Group-1 has largest atomic radius. It decreases across a period

What happens to the reactivity of elements in group a as atomic number increase across a period?
they do becaused they want to do it

How much does the number increase by as you go across a row on the periodic table?
The atomic number increases by 1 as one go across a row on periodic table. The elements are arranged in order of increasing atomic number.
What goes across the periodic table?
The periodic table is arranged by increasing atomic number, which moves from left to right across each row. As you move from left to right across a row, the elements increase in atomic number and atomic mass, with similar chemical properties grouped together.
Why do you think the scientists arrange the periodic table by increasing atomic number?
This is a general tendence for an arrangement. Also it is a relation between atomic number and atomic weigths of chemical elements.
How are the size of the elements effected on the periodic table?
Atomic size increase down the group and decreases across the period.
What do notice on the atomic number of elements in a row as one goes to the right of the table?
The atomic number increases from left to right across a period (row). This is because the atomic number is the number of protons in the nuclei of the atoms of each element. No two elements have the same atomic number. It is the protons that define an element.
Why is atomic number better than atomic mass for organizing the elements in the periodic table?
Atomic number is a unique number for each element. No two elements have the same atomic number. Atomic number is also the number of protons in the nuclei of the atoms of any given atom. Atomic mass, however, is the number of protons, neutrons and electrons.
