An anion is a negatively charged ion. An element can become an anion if it takes an extra electron such that it has one more electron than protons.
Atoms would preferentially taken an extra electron so that it can have a full octet and be more stable.
are some of the few elements that would have a -1 charge.
Answer:-
27.38%
Explanation:-
Molecular weight of sodium hydrogen carbonate NaHCO3
= 23 x 1 + 1 x 1 + 12 x 1 + 16 x 3
= 84 gram
Total sodium Na present in NaHCO3 = 23 x 1 = 23 gram
Percentage of sodium present=
Total sodium x 100/ (Total molecular weight)
= 23 x 100 / 84
= 27.38 %
A phospholipid has a charged head and an uncharged tail.
There are 600 hours.
explanation
each day has 24 hours and we want to know how much hours is equivalent to 25 days so we multiply 24 times 25 which is 600.
If polar covalent bonding results in a molecule with a positively-charged end and a negatively-charged end, the molecule is called D. a dipole.
