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+)
What determine an atoms size?
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
Nuclear charge increases across a period atoms become?
The atoms become smaller in atomic radius.
Which element has a smaller atomic radius bromine or gold?
The atomic radius of bromine is lower.
What happens to an atomic radius when an electrons is lost?
The positive ionic radius is smaller than the neutral atomic radius
Compared to the atomic radius of a sodium atom the atomic radius of a magnesium atom os smaller the smaller radius is primly a result of the magnesium atom having?
a larger nuclear charge
