Answer:
sorry this is a kind of confusing question.
Explanation:
atoms are made of 3 types of sub atomic particles- protons, neutrons and electrons
from these 3 particles, electrons are responsible for participating in chemical bonds. therefore chemical properties of elements are based on the number of electrons present.
valence electrons are the number of electrons in the outermost energy shell that are involved in chemical bonds.
atoms with same number of valence electrons are grouped in to columns called groups.
therefore elements of the same group have same number of valence electrons, hence similar chemical properties.
from the options given
only Be and Mg belong to the same group they both belong to group 2 with 2 valence electrons
therefore Be and Mg have similar chemical properties
answer is
1) Be and Mg
1500 just move the decimal to the right three times because its a positive <span />
Too freaking many... or maybe not many at all
Explanation:
The periodic table of elements has a rich diverse number of elements. Every element on the table is arranged based on their atomic numbers into their respective groups and columns.
The coining of words from the table is done creatively by combining symbols of elements.
Here are some of the world list:
TaXEs , TeAcH ,TeAm , TeTaNUS , CoW,, CoVEr COY
