Which ion in the compound K and Br is larger?
The Br ion is larger than the K ion. This is because the Br ion has more electron shells than the K ion, leading to a larger atomic radius.
Why k is more reactive than na?
Potassium (K) is more reactive than sodium (Na) because potassium has a lower ionization energy and a larger atomic radius compared to sodium. This makes it easier for potassium to lose an electron and form a positive ion, leading to greater reactivity.
How does the potassium ion channel selectively allow potassium ions k to pass through but block sodium ion Na?
Potassium ion channels are selective to potassium ions due to a filter region that is just the right size to accommodate K+ ions while excluding larger Na+ ions. The filter region contains negatively charged amino acids that attract K+ ions while repelling Na+ ions, further aiding in selectivity. This size and charge-based selectivity allow the potassium ion channel to facilitate the passage of potassium ions while effectively blocking sodium ions.
What elements will most likely form an ion with a plus 1 charge?
Sodium (Na), Lithium (Li), or Potassium (K).
What is the ion symbol for sodium?
The ion symbol for sodium is Na+.
Which ion in the compound K and Br is larger?
The Br ion is larger than the K ion. This is because the Br ion has more electron shells than the K ion, leading to a larger atomic radius.
What is ion released by many bases?
the hydroxyl ion (OH-) and the metal ion (Na+, Ca+, K+, etc.)
What hormone regulates Na plus and K plus ion concentration?
aldosterone
What sort of ion distributions are established and maintained by Na -K pump activity?
high Na+ concentration in the extracellular fluid; high K+ concentration in the cytoplasm
What are two likely reasons a Cl ion cannot pass through a Na ion channel?
the Cl- ion is larger than the Na+ ion, making it too big to fit in the channelthe charges are opposite, repelling the Cl- ion from the channel

What is the symbol for an ion of sodium?
Sodium forms the Na+ ion.
What is the ion symbol for sodium?
The ion symbol for sodium is Na+.
what are monoatomic ions?
Monatomic cations with a single possible charge. H+ = hydrogen ion Mg2+ = magnesium ion Al3+ = aluminum ion. Li+ = lithium ion Ca2+ = calcium ion. Na+ = sodium ion Sr2+ = strontium ion. K+ = potassium ion Ba2+ = barium ion.
What is the ion formula of potassium?
The ion formula of potassium is K+.
