Because carbon is the element at the top of Group 4A, it is also the atom with the lowest mass.
What is the smallest atom in Period 4?
Helium has the smallest atomic radius of all the noble gases. This is due to trends in the periodic table, as well as the nuclear charge that keeps the valence electrons close to the nucleus.
What element is in Group 4 Period 4?
Group 4 is the second group of transition metals in the periodic table, which includes four elements: titanium (Ti), zirconium (Zr), hafnium (Hf), and rutherfordium (Rf). The family or titanium group is also known as such because of its lightest member.

What is the largest atom in Group 4?
The table’s center column has a row of four large atoms, which are the world’s largest known molecules: fluorine (F), chlorine (Cl), bromine (Br) and iodine (I). The greatest known particles in Cs are tucked in the lower left corner of the table. Cesium’s atomic radius is given as 273.1 pm [1], 265 pm [2], 265.5 pm [3] or 260 pm [4]. However, Rubidium has even larger atoms, with an atomic radius of about 30 ppm less than that of cesium.
Which is the largest atom in Group 14 4A?
The most massive member of group 14, lead, is a soft and malleable metal that the ancient Romans used as writing tablets, cookware, and plumbing pipes made from thin lead foils. (Remember that tin and lead are derived from their Latin names: Sn for stannum and Pb for plumbum.)
Which atom is biggest in size?
The atomic radius in a group rises from top to bottom and from left to right, with francium being the largest and helium being the smallest element.

What is the chemical symbol for helium?
He
Why does boiling point increase down Group 4?
If we look at the melting and boiling points as we move down Group 4, making any sensible judgments about the shift from covalent to metallic bonding is difficult. As atoms get bigger and the connections longer, the trends reflect an increasing degree of weakness in the covalent or metallous bonds.
What is the element in Group 3 Period 4?

- 2 Li 3 C 6
- 3 Na 11 Si 14
- 4 K 19 Ge 32
- 5 Rb 37 Sn 50
What element is in Group 15 and Period 4?
Arsenic. Arsenic (As) is an element in group 15.
Which atom is the smallest?
The smallest atom is helium, with a radius of 32 pm, whereas the largest is caesium, which measures 225 pm.
Which group has the highest metallic character?
The alkali metals in group 1 are the most reactive, with cesium being the last element for which we have experimental data. Because francium is so rare and radioactive, there is no evidence that it is the most metallic substance.
What elements have the most atoms?
In their search for the ideal, most people overlook the fact that all gases behave differently—and have distinct properties. Helium has the greatest number of atoms and is thus best suited for this job. Determine each element’s atomic weight (in grams per mole) and divide the given mass of the element by its atomic weight to obtain the number of moles of each substance.
What is Group 4A called?
The nonmetal carbon (C), metalloids silicon (Si) and germanium (Ge), metals tin (Sn) and lead (Pb), and yet-unnamed artificially-produced element ununquadium (Uuq) are members of Group 4A of the periodic table.
Do Group 4A elements gain or lose electrons?
All of the elements in this category have a propensity to lose their valence electrons. A +4 charge is given to an element when it loses all four valence electrons, or has a +4 oxidation state.
What is the most electronegative element in Group 4A?
Francium is one of the least electronegative elements, whereas fluorine is one of the most electronegative. (Though neon, argon, and helium are not mentioned in the Pauling electronegativity scale, they have the highest electronegativity according to Allred-Rochow.)
