Which has smaller atomic size helium or fluorine or neon?
He has the smaller atomic size. Fluorine has the larger atomic size from these 3. He is a noble gas.
Why does atomic size increase from left to right across a period?
atomic size decreases across a period
What happens to the atomic size from the top to the bottom of the periodic table?
The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
WHAT is the atomic size of potassium?
erwar
How does atomic size generally go on the periodic table?
Atomic radius generally decreases as you go from left to right in the same period. Atomic radius increases as you go down the same group.

What happens to the atomic size from the top of the periodic table to the bottom?
The atomic size increase from top to bottom of Periodic Table. As the number of shells increases from top to bottom, the atomic size increases.

The atomic size increase from top to bottom of periodic table. As the number of shells increases from top to bottom, the atomic size increases.
What property increases going down a group in periodic table?
Atomic size, number of shells (or energy levels) and electropositivity increases down a group on the periodic table.
When you go across the periodic table how does the atomic size go?
Atomic size decreases across the rows of the periodic table
What is the periodic trend for atomic size from top to bottom in a group?
The size of an atom refers to its atomic radius. Atomic radius generally increases down a group. This is because the number of energy levels increase down a group with each additional period. Each of the subsequent energy levels are larger than the last, increasing the distance of the electrons from the nucleus, which increases the atomic radius.Atomic radius generally decreases across a period. This is because electrons are being added to the same energy level at the same time that protons are being added to the nucleus. This creates a stronger force of attraction by the nucleus for the electrons, which pulls the electrons closer to the nucleus, decreasing the atomic radius.It is important to note that the periodic trends are not laws. There are exceptions to the general trends in both the representative elements and the transitional elements.
How do elements change going down the periodic table?
Down a group, the atomic number generally increases, size increases, ionization energy decreases, reactivity increases.
