Ionization of potassium (K) results in a positive ion, K+, which has the electronic configuration of Ar. The ionization of chlorine (Cl) results in a negative ion (Cl-), also with the electronic configuration of Ar. Adding an electron always increases the size of an atom, and removing one always decreases its size.
Note that both K+ and Cl- have the same number of electrons, but Cl- is larger than K+, because they are not as tightly held to the nucleus in Cl- because it has 2 less protons than potassium does. The size of the electron cloud determines the size of the atom and with fewer positively charged protons to pull the same number of electrons in close to the nucleus the electron cloud is larger for Cl-.
Both, electronegativity and ionisation potential, will increase across (from left to right) a period and will decrease down a group.
Potassium levels DECREASE heart rate, and maybe lead to severe cardiac arrest.and for sure, this is a mechanism of how potassium level in ECF can decrease heart rate:first, the potassium level increase in ECF making its efflux increase, due to activation of potassium channels in pacemaker cells, then the slope of pacemaker action potential will decrease, which means that the duration of one beat is prolonged, and this lead to decrease the numbers of beats in one minute, which by turn means that the heart rate is decreased.
An extracellular increase of potassium (increase of intracellular Sodium) causes depolarization. The opposite, I presume, meaning high intracellular potassium (inside cell) and high extracellular sodium (outside cell) would be hyperpolarization
The pH remain constant.
When adjusting your cash flow statement, you increase (add) a decrease of inventory and decrease (subtract) an increase of inventory
Increase means to get more and decrease means to get less
you increase or decrease mass by taking the mass out
Increase or decrease the circle's diameter
< = decrease > = increase
The increase in concentration increases the density and decrease causes the decrease in density.
Increase decrease. The frequency MUST decrease.
it depends on what you mean by "increase" and "decrease." It can actually go both way. the alimony I get can this increase
Buffering compounds are weakly ionised, addition of hydrogen or hydroxide ions (in modest amounts), shift the degree of ionisation of the buffer which produces an increase or decrease in the hydrogen or hydroxide ions provided by the buffer itself. This change in ionisation of the buffering compound approximately compensates for the addition.
there is an increase in atomic number and atomic size down the group due to addition of extra shells.this increase in the atomic size overcomes the effect of an increase in the nuclear charge.Therefore ionisation energy decreases with an increase in atomic size i.e.,it decreases as one moves down a group..
An increase in an electrical current will cause magnetism to increase but a decrease in an electrical current will cause magnetism to decrease.
demand in supply is the basis of it's increase and decrease
increase or decrease in what?
When the temperature increase the pH of water decrease.
