Why are potassium and caesium rather than lithim used in photoelectric cells?
Potassium can loose electron easily . Comparatively Lithium have high ionisation energy and low level of loosing electron while absorbing light energy.
To form an ion what does a calcium atom gain or loose?
An atom of Calcium will lose an electron to become a posotive ion.
Is calcium carbonate or potassium carbonate more soluble in water?
Yes and no depending on what you mean by the word potassium. By itself, potassium is a metal and cannot dissolve in water because it reacts with water very rapidly. So rapidly and with so much energy given off, the hydrogen the reaction produces ignites! The reason this happens is that potassium as an element (metal) has a loosely held single electron in its atom. The atom is so very high strung with this loose electron and would be so much more relaxed if it got rid of it that it'll practically give it to almost any other atom it comes in contact with. That's why potassium doesn't exist in nature as an element and why it reacts with water, even the oxygen in air. After it gives up that single electron, it becomes an ion and part of an ionic compound. It the case of reacting with water - potassium hydroxide (KOH). The OH comes from ripped apart water (H2O) and the left over H becomes H2 when it meets up with another left over H atom. Potassium ion, on the other hand is very soluble in water. So, is it possible that potassium ions can exist in water? Yes! Is it possible that potassium metal can exist in water? No! Never!
What category is hydrogen in?
Hydrogen is the first element in the periodic table. It is a gas. It can either donate or receive an electron, depending on what it bonds with.

What kind of atom tends to loose one electron?
The Alkali Metals loose one electron in order to achieve a nobel gas configuration.
Why the metal is very reactive?
Metals , generally, have electronic configuration: with outermost electron having 1,2 or 3. Since, they can easily attain noble gas configuration to attain stability; they readily loose electron.
Why does cu show variable sub shell configuration?
Because copper loose electron from its penultimate outer shell
Why are potassium and caesium rather than lithim used in photoelectric cells?
Potassium can loose electron easily . Comparatively Lithium have high ionisation energy and low level of loosing electron while absorbing light energy.
Why do atoms gain loose or share electrons?
Atom loose or gain electron to make its octet complete. It is done to achieve inert state.
The element Potassium has an atomic number of 19 and an atomic mass of 39 Draw the ion that forms when it gains or loses an electron or electrons?
When Potassium (K) gains one electron, it forms a positive ion with a charge of +1, written as K+. The electron configuration becomes 1s^2 2s^2 2p^6 3s^2 3p^6. When Potassium loses one electron, it forms a negative ion with a charge of -1, written as K-. The electron configuration becomes 1s^2 2s^2 2p^6 3s^2 3p^6 4s^1.
Does pottassium (k) gain or lose electrons?
Potassium is more likely to lose its electron to become a positive ion.
How many electrons does potassium need to gain or loose to become more stable?
Potassium (K), an Alkali Metal in Group 1 with atomic number 19, has a single valence electron in its outermost shell. Therefore it only needs to lose one electron in order for the element to become stable.
Why does lithium have a smaller atomic radius then potassium?
because the second ionisation means removing the second electron from the potassium atom. Potassium only has one electrin in its outer most shell so the second electron would be in another electron shell which is closer to the nucleus meaning there is a stronger attraction to that electron because of the protons in the nucleus which are positive and attrct the negative electrons so more energy is needed to remove the second electron
Do bananas lose potassium after being cooked?
no banana does not loose the potassium after cooked.
Why is it easy for a metal to loose an electron?
Metals useually have few valence electrons and they loose electrons from their outermost shell thus, forming an ion with positive charge (cations). This is because it is easy for metals to loose electron and attain stable or octet configuration similar to rare gases. Hence to attain stability metals lose valence electrons. E.g. sodium (At no. =11 ; electronic configu-1s2, 2s2, 2p6, 3s1) metal has one valence electron and it is easy for it to loose 1e rather to gain 7e to attain stable configuration. Hence it loose 1e forming Na+ cation.
Why do groups 1 and 2 in the periodic table react easily?
The elements in group one and two react so easily because they have only one or two valence electrons, and the non metals, want those electrons. These group elements loose 1 or 2 electron to be stable instead of gaining 6 or 7 to complete the outer shell attain stable electronic configuration of a noble gas.
