No, a smaller atomic radius does not inherently mean a negative charge. Atomic radius refers to the size of an atom, which is influenced by factors like the number of electron shells and the effective nuclear charge experienced by the electrons. A negative charge indicates that an atom has gained extra electrons, but this can occur in atoms of various sizes. Thus, atomic radius and charge are related but not directly indicative of one another.
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+)
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
The atoms become smaller in atomic radius.
Na has a larger atomic radius than Br. This is because Na is a metal and atoms in metals have larger atomic radii compared to nonmetals like Br, which has a smaller atomic radius due to its higher effective nuclear charge.
The atomic radius of bromine is lower.
The smaller atomic radius of a magnesium atom compared to a sodium atom is primarily a result of the increased nuclear charge in magnesium due to the higher number of protons. This increased nuclear charge pulls the electrons closer to the nucleus, resulting in a smaller atomic radius for magnesium.
Fluorine has a smaller atomic radius than chlorine because fluorine has a higher effective nuclear charge due to its lower energy level and smaller atomic size, causing the outer electrons to be pulled closer to the nucleus. This results in a stronger attraction between the positive nucleus and the negative electron cloud, leading to a smaller atomic radius in fluorine compared to chlorine.

the positive ionic radius is smaller than the neutral atomic radius
A smaller atomic radius for beryllium would result from an increased positive charge in its nucleus, leading to a stronger attraction between the nucleus and the valence electrons. This increased attraction pulls the electron cloud closer to the nucleus, resulting in a smaller atomic radius.
The atomic radius depends on the the number of electron shells, total negative charge, positive charge of the nucleus, atomic mass.
Helium has the smallest atomic radius out of hydrogen, sodium, and lithium. This is because helium has a full electron shell, leading to a smaller effective nuclear charge that pulls the electrons closer to the nucleus, resulting in a smaller atomic radius.
The negative ionic radius is larger than the neutral atomic radius
The atoms become smaller in atomic radius.
A plus exponent signifies that the atomic radius decreases as you move across a period due to an increase in the effective nuclear charge, pulling the electrons closer to the nucleus. This results in stronger attraction between the nucleus and the outermost electrons, making the atomic radius smaller.
Potassium's atomic radius is smaller than rubidium's because potassium has fewer energy levels of electrons.
Fluorine has more electronegativity, meaning it is more "desperate" to obtain electrons. Its nucleus is the most attractive of all elements.
