How does the presence of core electrons affect the atomic radius of elements?

When there is an anion (negative charge) the radius will be larger because it is more full whereas it will be smaller if it is a positive charge because of less electrons. ex largest to smallest radius (K-,K, K+)

In a period the atomic radius decrease (with several exceptions) from left to right.

What do chemist use to stand for atoms or elements?
Atomic symbols are used to represent elements, a negative (-) and a psoitive (+) represent electrons and protons, respectively. Chemicals or other compounds are often written as a combination of atomic symbols with subscripts to indicate the presence of multiple atoms.
What are electrons on a periodic table?
Periodic table lists the elements in the increasing order of atomic number. Atomic number = Number of protons = Number of electrons
Are protons neutrons and electrons elements?
No. they all are sub atomic particles.
How do you figure the atomic mass of element when you have electrons?
The term atomic mass is used only for isotopes; for chemical elements the term atomic weight is recommended.But atomic masses and atomic weights include also all electrons.
Is there any relationship between atomic mass and number of proteins and electrons?
the atomic number is equal to the number of electrons(-) and protons(+): that is why elements have no charge, as a neutron is neural
What properties did Mendeleev position the elements on the table?
Mendeleev created his Periodic Table at the time when presence of sub-atomic particles like electrons, protons and neutrons were not discovered.So, the term atomic number was not known till now. So , he positioned the elements in increasing order of atomic mass because Atomic Mass of many elements discovered till then were known.

What effect does the nucleus have on atomic spectra of different elements?
Aside from determining how many electrons the atom has, the nucleus does not affect the spectra of that atom in any way.
How are the elements in a period different?
By their atomic weight..protons and electrons.
Are protons neutrons and electrons elements?
No. they all are sub atomic particles.
How do you find out the atomic number of an element?
Atomic number is the no. of protons or no. of electrons in an atom .

What is the number of protons electrons and neutrons in n-14?
Nitrogen-14: 7 Protons, 7 Electrons, 7 Neutrons To work this out in the future for other elements: Protons = Atomic Number Electrons = Atomic Number Neutrons = Atomic Mass - Atomic Number Hope this helps!
What does an elements atomic number respresnt?
The atomic number of an atom represents the number of electrons as well as the number of protons.
