Explanation:
solve fsolve for x in terms of r.
rx + 24 = -9or x in tsolve for x in terms of r.
rx + 24 = -9erms of r.
solve for x in terms of r.
rx + 24 = -9
rx + 24 = -9
Answer:
Oxygen has 2 energy levels
Explanation:
If you add them up: 2+2+6 = 10, you will know it's Neon, which is written as Ne
The subscript 2 indicates number of Cl atoms
<h3>Further explanation
</h3>
The molecular formula shows the number of atoms of a compound
whereas the empirical formula is the simplest comparison of the atoms making up the compound
MgCl₂ is an ionic compound composed of Mg and Cl atoms
Mg is in group 2 which has a +2 charge, while Cl is in the Halogen group which has a charge of -1
If the two are bonded, the 2 electrons released by Mg will be bound by 2 Cl atoms, each of which atoms of Cl need 1 more electron in order to obtain a stable electron configuration such as a noble gas
So the number 2 in the MgCl compound indicates the number of Cl atoms
