Is BA more reactive than na?

Is BA more reactive than na?

Explanation: No Sodium is more reactive than Barium.

Is BA less reactive than CA?

yessss bec. in periodic table it is placed in such an order that its reactivity is greater than calcium and also its atomic no. is greater than calcium so it has more no. of electrons so it is more reactive….

Which one is more reactive among Na and K explain?

As potassium is larger than sodium, potassium’s valence electron is at a greater distance from the attractive nucleus and is so removed more easily than sodium’s valence electron. As it is removed more easily, it requires less energy, and can be said to be more reactive.

Is electrochemical series and reactivity series Same?

Basically, ECS (electrochemical series) is to refer for aqueous state. On the other hand, reactivity series is for the reaction without being in aqueous state. Reactivity series is about the reactivity of the chemical substances in a particular reaction. Like calcium is more reactive than magnesium.

Which is most reactive nonmetal?

element fluorine
The element fluorine is the most reactive nonmetal. It is not found in nature as a free element. Fluorine gas reacts explosively with many other elements and compounds and is considered to be one of the most dangerous known substances.

Which is the less reactive metal?

Silver, gold, and platinum are metals with the least reactivity. They are found in nature.

Which is the correct order of reactivity series Mg Ca Na K?

Answer: Option (b) K < Na < Ca < Mg is correct answer.

Which of the following order is correct for the reactivity of metals Na au Fe Mg?

Answer: B. Na > Mg > Fe > Au is the correct order.

Why is K more reactive than CA?

Reactivity of an element depends on upon the ionisation enthalpy. Smaller the ionisation enthalpy, greater is the reactivity. As potassium has smaller ionisation enthalpy than calcium. Thus, potassium is more reactive than calcium.

What is the meaning of reactivity series?

Reactivity series. Not to be confused with Electrochemical series. In chemistry, a reactivity series (or activity series) is an empirical, calculated, and structurally analytical progression of a series of metals, arranged by their “reactivity” from highest to lowest. It is used to summarize information about the reactions

How does the reactivity of elements vary from top to bottom?

Reactivity of element decreases on moving from top to bottom in the given reactivity series. In the reactivity series, copper, gold, and silver are at the bottom and hence least reactive. These metals are known as noble metals. Potassium is at the top of the series and hence most reactive.

How does the reactivity series affect the electro-positivity of metals?

The electro positivity of the elements also reduces while moving down the reactivity series of metals. All metals that are found above hydrogen in the activity series liberate H 2 gas upon reacting with dilute HCl or dilute H 2 SO 4. Metals that are placed higher on the reactivity series have the ability to displace metals

Which of the following metals is the least reactive?

In the reactivity series, copper, gold, and silver are at the bottom and hence least reactive. These metals are known as noble metals. Potassium is at the top of the series and hence most reactive. Reactivity of some metals are given in descending order.
