Who react faster with acids Na or K?
Potassium (K) will react faster with acids than sodium (Na) because potassium is more reactive than sodium due to its lower ionization energy. This makes potassium more likely to displace hydrogen in acids and react more vigorously.
Is k or mg more reactive?
Potassium (K) is more reactive than magnesium (Mg) because potassium is a more reactive metal due to its lower position in the reactivity series. Potassium reacts more violently with water and air compared to magnesium.
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.
Why K and Na are kept in kerosene?
K and Na are kept in kerosene to prevent them from reacting with oxygen and moisture in the air, which would quickly tarnish their surfaces. Kerosene forms a protective layer that helps to maintain the reactivity and appearance of these reactive metals.
Is calcium more reactive than aluminium?
yes. because calcium is almost never found in nature due to its high reactivity with water, but we can find copper metal in nature.
Name an alkali metal that is more reactive than K Na or Li Name an alkali metal that is less reactive?
Hydrogen (H) is more reactive. Francium (Fr) is less reactive.
Is Rb more reactive then Li k Na Cs?
Yes, rubidium (Rb) is more reactive than lithium (Li), potassium (K), sodium (Na), and cesium (Cs). In the alkali metal group, reactivity increases as you move down the periodic table due to the increasing atomic size and the decreasing ionization energy, which makes it easier for the atoms to lose their outermost electron. Thus, Rb, being below K and Na, is more reactive than all of them. However, cesium (Cs) is even more reactive than rubidium.
What is the most reactive among Li Na K Rb?
Lithium (Li) is the most reactive among Li, Na, K, and Rb due to its small atomic size and low ionization energy, making it easier for it to lose its outer electron and form compounds. Sodium (Na) would be next in reactivity, followed by potassium (K) and then rubidium (Rb).
Who react faster with acids Na or K?
Potassium (K) will react faster with acids than sodium (Na) because potassium is more reactive than sodium due to its lower ionization energy. This makes potassium more likely to displace hydrogen in acids and react more vigorously.
What Group 1A elements is the most reactive cs Li K Na?
K
Is Ag more reactive than K?
Potassium (K) is more reactive than silver (Ag). Potassium is an alkali metal on the far left side of the periodic table, making it highly reactive with water and oxygen. Silver is a transition metal that is more stable and less reactive compared to alkali metals like potassium.
Is k or mg more reactive?
Potassium (K) is more reactive than magnesium (Mg) because potassium is a more reactive metal due to its lower position in the reactivity series. Potassium reacts more violently with water and air compared to magnesium.
Is plasma membrane is more permeable to K than Na during rest?
Yes, the plasma membrane is more permeable to K+ than Na+ during rest because of the presence of leak channels that are more selective for K+ ions. This creates a resting membrane potential where K+ plays a more significant role in establishing the internal negative charge of the cell.
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.
Why Na is less reactive than K?
Potassium's 1 valence electron is farther away from its nucleus than sodium's 1 valence electron is from its nucleus. Potassium is one period up from sodium (well, down on the p.t.e., but up in number of energy levels), so the attraction between potassium's nucleus and outermost electron is a little less than in sodium, so that electron is more likely to go flying, which makes potassium more reactive.
What is more stable K or Kr?
Kr (krypton) is more stable than K (potassium) due to its full valence shell of electrons, which provides greater stability. Potassium is a highly reactive metal that readily loses its single valence electron, making it more chemically reactive and less stable than krypton, which is a noble gas with a full valence shell.
Why K and Na are kept in kerosene?
K and Na are kept in kerosene to prevent them from reacting with oxygen and moisture in the air, which would quickly tarnish their surfaces. Kerosene forms a protective layer that helps to maintain the reactivity and appearance of these reactive metals.
