Answer:
Valence electrons
Explanation:
The formation of phosphorus trifluoride is orchestrated by the sharing of the valence electrons between phosphorus and fluorine.
This is called covalent bonding. In covalent bonding, elements with zero or very small electronegativity combines together. Such bonding occurs between non-metals.
For this bond to form, phosphorous shares its 5 electrons with the 3 of the fluorine.
One mole represents 6.022∙1023 separate entities, just like one dozen represents 12 objects. So, if there are 6.022∙1023 H2O molecules, that is the same as one mole of water.
Answer:
each of two or more forms of the same element that contain equal numbers of protons but different numbers of neutrons in their nuclei, and hence differ in relative atomic mass but not in chemical properties; in particular, a radioactive form of an element.
"some elements have only one stable isotope"
Explanation:
Platemovement can cause Tsunami
Answer:
In CO there is one mole of Carbon and one mole of Oxygen so the number of atoms will be for two mols
