What is the group number in standard and roman numerals of potassium?
the group number in standard and roman numerals of potassium is as follows .the group number in standard of potassium is Group 1 .the group number roman numerals of potassium is Group I.
What is potassium's number of valance electrons?
Potassium has one valence electron. It belongs to Group 1 of the periodic table, which means it has one electron in its outermost energy level.
How does calcium first ionization energy compare to the first ionization energy of magnesium and potassium?
Calcium's first ionization energy is lower than that of magnesium but higher than that of potassium. This is due to the increasing atomic size down the group, which decreases the effective nuclear charge felt by the outermost electron. Magnesium, being higher in the group, has a smaller atomic radius and a stronger attraction between the nucleus and its valence electron, resulting in a higher ionization energy. Conversely, potassium, being further down the group, has an even larger atomic radius, leading to a lower ionization energy than calcium.
What group and period is potassium?
the group is 18
What group is k in and what is the name of the elements?
Potassium is in group 1 and the group elements are hydrogen, lithium, sodium, potassium, rubidium, cesium, francium
What is the group number in standard and roman numerals of potassium?

The valence electrons of which element has the highest energy hydrogen lithium sodium or potassium?
The element with the highest energy valence electrons among hydrogen, lithium, sodium, and potassium is potassium. Potassium is in the first group of the periodic table, which means it has one valence electron located in the highest energy level (n=4 in the case of potassium).
What is potassium's number of valance electrons?
Potassium has one valence electron. It belongs to Group 1 of the periodic table, which means it has one electron in its outermost energy level.
What is the period and group number of potassium?
Potassium belongs to group-1. It has one valence electron.
What has 1 valence electron but has 4 energy levels?
This elemental atom will be in (column:) group 3, or 13, and (row:) period 4: 21-Sc or 31-Ga
What provides energy that drives the sodium-potassim pump?
The energy for the sodium-potassium pump is derived from the hydrolysis of ATP molecules. ATP releases energy when its phosphate group is cleaved, providing the necessary energy to move sodium ions out and potassium ions into the cell through the pump.
How does potassiums atomic radius compare to that of sodium?
Potassium has a larger atomic radius compared to sodium. This is because as you move down a group in the periodic table, the atomic radius increases due to the addition of more energy levels. In the case of potassium and sodium, potassium is located below sodium in the same group, resulting in a larger atomic radius for potassium.
Which element has a first ionization of 418kJmol?
The element with a first ionization energy of 418 kJ/mol is strontium (Sr). Strontium is a metallic element in Group 2 of the periodic table, and its first ionization energy corresponds to the energy required to remove one electron from a neutral strontium atom to form a +1 ion.
What is the number of the group that has potassium in it?
It is group 1.
What group and period is potassium?
the group is 18
Which is more reactive sodium or lithium or potassium?
Potassium is more reactive than lithium, which is more reactive than sodium. This trend is based on the alkali metal group's reactivity, with reactivity increasing as you move down the group due to the decreasing ionization energy and increasing atomic size.
What element has the larger first ionization energy cesium or potassium?
Cesium has a larger first ionization energy compared to potassium. This is because cesium is located further down the periodic table in the alkali metal group, meaning it has a larger atomic radius and a lower effective nuclear charge, both of which make it easier to remove an electron from potassium than from cesium.
