Which element in Period 4 has the largest atomic size?
francium
Atomic radii vary in a predictable way across the periodic table. As can be seen in the figures below, the atomic radius increases from top to bottom in a group, and decreases from left to right across a period. Thus, helium is the smallest element, and francium is the largest.
Which element in Period 4 has the largest electron affinity?
Chlorine has the highest electron affinity among the elements. Its high affinity can be attributed to its large atomic radius, or size. Because chlorine’s outermost orbital is 3p, its electrons have a large amount of space to share with an incoming electron.

Is the biggest atom in Period 4?
For Period 3, the Group1 Alkali Metal (potassium, lowest Z) has the largest atomic radius and the Group 7/17 Halogens & Group 0/18 Noble Gas (bromine & krypton, highest Z’s) have the smallest atomic radii (there is some uncertainty in the noble gas radii)….

Which element in Period 4 has the most metallic properties?
The most metallic element is francium.
Why is a period 4 element on the periodic table?
Period 4 element. The periodic table is laid out in rows to illustrate recurring (periodic) trends in the chemical behaviour of the elements as their atomic number increases: a new row is begun when chemical behaviour begins to repeat, meaning that elements with similar behaviour fall into the same vertical columns.
Which is element has the largest atomic mass?
Oganesson has the highest atomic number and highest atomic mass of all known elements. Click to see full answer. Likewise, which elements has the largest atomic radius? The element which has the largest atomic radius is Cesium.
Which is the most poisonous element in period 4?
Arsenic (As) is an element in period 4, between germanium and selenium. Arsenic, as mentioned above, is often used in semiconductors in alloys with germanium. Arsenic, in pure form and some alloys, is incredibly poisonous to all multicellular life, and as such is a common component in pesticides.
Which is the most resistant element in period 4?
Chromium. Chromium (Cr) is an element in period 4, between vanadium and manganese. Chromium is, like titanium and vanadium before it, extremely resistant to corrosion, and is indeed one of the main components of stainless steel. Chromium also has many colorful compounds, and as such is very commonly used in pigments, such as chrome green .
