For metals, reactivity increases down a group and from right to left across a period. Non metals, reactivitt increases up a grouo and from left to right across a period. Francium is the most reactive metal and fluorine is the most reactive non-metal.
Answer:
See explanation
Explanation:
XeF4 has a square planar structure. There are six electron pairs on the valence shell of the central atom. This gives rise to an octahedral geometry based on valence shell electron pair repulsion theory.
There are two lone pairs of electrons present on the central atom, hence the four bond pairs are found to occupy the corners of a square thereby giving a square planar compound. The two lone pairs are found above and blow the plane of the square.
The answer is electrolyte.
That is electrolyte is the type of minerals that is associated with maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential.
Sodium, potassium and chlorides are the macrominerals that are known as the electrolytes, that are very important for the function says maintaining water balance, osmotic equilibrium, acid-base balance and intracellular/extracellular differential .
Ok...what was the question
Answer: True
Explanation:
I answered your other one and its bascily the same thing a molecule made of atoms from different elements. All compounds are molecules, but not all molecules are compounds. ... There are two main types of chemical bonds that hold atoms together: covalent and ionic/electrovalent bonds. Atoms that share electrons in a chemical bond have covalent bonds.
