Answer:
I think its 1.2 cause I divided 15.5 with 12 and got 1.2 as an answer
Answer:
All atoms heavier than barium
Explanation:
In the periodic table, elements are divided into blocks. We have the;
s- block elements
p- block elements
d- block elements
f- block elements
However, immediately after Barium, we now encounter elements that have f-orbitals. Barium possesses a fully filled d-orbital. Hence after it, we see elements with 4f and 5f orbitals called the Lanthanides and actinides. The elements following the lanthanide and actinide series possess completely filled f-orbitals as inner orbitals.
Hence elements heavier than barium all possess f-orbitals.
Three examples of environmental, industrial and bio-chemistry are listed below:

- industrial chemistry: industrial inorganic chemicals, industrial organic chemicals, and agricultural chemicals
- bio-chemistry: genetic, immunology, and enzymology
<h3>Meaning of Chemistry</h3>
Chemistry can be defined as a branch of science which is concerned with the substances matter is composed of, their properties and reactions,
Chemistry also deals with the use of such reactions to form new substances.
