What three groups are not included in the alien periodic table?
The alien periodic table does not include transition metals, lanthanides, actinides, and elements beyond the atomic number of 50.
What is the symbol for Apstrom?
The halogens are apstrom (A), vulcania (V), and kratt (Kt). Vulcania (V) is in the same period as quakzil (Q) and wobble (Wo).
Which is the most reactive alien metal?
xtalt
Which is the lightest element in the world?
Hydrogen
Which metal has lowest atomic mass?
Ernst
Which metal is smallest?
On this measure, at least, sodium is a metal all the way down.
What is the lightest metal?
Magnesium: The Lightest Structural Metal
- Magnesium is the lightest structural metal and abundantly available in the earth’s crust and seawater.
- Magnesium is the third most commonly used structural metal, following steel and aluminum.
Which metal has the smallest size?
Thus the smallest among the given options is Na [sodium].
What are 2 alkali metals?
The alkali metals are six chemical elements in Group 1, the leftmost column in the periodic table. They are lithium (Li), sodium (Na), potassium (K), rubidium (Rb), cesium (Cs), and francium (Fr).
Which has the largest atomic radius?
Francium
What element has the largest metallic property?
cesium
Which is the most non metallic?
The most non metallic element is fluorine.
What has the highest metallic character?
What element has the most metallic character?
- franium (element with highest metallic character)
- caesium (next highest level of metallic character)
- sodium.
- copper.
- silver.
- iron.
- gold.
- aluminium.
What elements has the largest atomic radius Why?
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 has lowest atomic radius?
Helium
What element has the second largest atomic radius?
(A) Trends in the Atomic Radius of Elements in Period 2
| Element | Li | Be |
|---|---|---|
| Energy Level being filled (Valence Shell) | second (L) | second (L) |
| Nuclear Charge (charge on all protons) | 3+ | 4+ |
| Atomic Radius (pm) | 134 | 90 |
| General Trend | (largest) | → |
What element has the largest atomic number?
Oganesson
Is there an element 119?
Ununennium, also known as eka-francium or element 119, is the hypothetical chemical element with symbol Uue and atomic number 119. Ununennium and Uue are the temporary systematic IUPAC name and symbol respectively, which are used until the element is discovered, confirmed, and a permanent name is decided upon.
