Is F more active than Cl?
They are both from the same group, yes. But F is above Cl so it means that the F's valence shell is nearer the nucleus (or at "lower level") than the valence shell in Cl, which causes F to have more effective nuclear charge. This fact explains the more electron affinity* in F in relation to Cl and therefore F is more reactive. * - electron affinity refers to a free atom. electronegativity refers to an atom in a molecule.
What highly active metal is a liquid it has 1 valence electron?
The lowest melting metal in group 1 (with 1 valence electron) is Francium (300 K, though not accurate). However it is not a liquid at room (or standard-) temperature. It is very reactive, but there are no stable isotopes (longest halftime 4 minutes for the most common found)
Is a atom with 7 neutrons 6 protons and 6 electrons active or inert?
active
What is the active alkaline earth metal with 56 protons?
Barium
When are active and passive transport and their types used?
Active transport uses energy in the form of ATP. Active can force electrons against the electron gradient as in the electron transport chain. Passive transport does not use energy and an example of passive transpost is osmosis.
Which group of metals is charterised by a single valence electron and very active atoms?
Those are the alkali metals.
How can you determine the most active metal?
You can determine the reactivity of a metal by looking at it's valence electrons. For example if the atom has one electron in it's valence shell it is more reactive because it wants to get rid of it and have a full valence shell.
What valence electrons has in rubidium?
The Rubidium valance shell is a radio active substance
Why are alkali metals extremely reactive?
There is only one electron in the outer most electron shell. With the lighter (less massive) alkali metals, there are less electron shells, between the outer most electron and the nucleus. Since the nucleus is positive(Protons) it more strongly holds the outer most electron. However, when going down the Alkali (Group 1) metals there are more electron shells, so the outer most electron is further away from the nucleus, and thereby less strongly held. This is evidenced by Lithium (The least massive) which only slowly effervesces in water. At the bottom of the group Francium ( The most massive) is explosive in water. NB Francium is not used in the open laboratory because it is also radio-active.
Is an electron transport chain passive transport or active transport?
passive transport since the protons are moving down their concentration gradient back into the mitochondrial matrix.
What element is more active Cs or K?
This question is meaningless without more information. What is meant by 'active'? If you mean reactive, then they are similar, both being alkali metals with 1 valence electron.
Which group of elements is the most active and why?
The alkali metals, group one on the periodic table. Starts with Lithium (Li) and ends with Francium (Fr). Or at least until Ununnunium is discovered, as it will be thenext alkali metal. The reason for their high reactivity is that they have only one valence electron. Valence electrons are the electrons that are involved in forming bonds with other elements. With only one valence electron, the atomic radius (how far away from the nucleus electrons can travel) is at its largest, making it so much easier for the electron to be taken by an other element that needs one valence electron, such as Chlorine (Cl). The reason that it is hard to find pure Sodium (Na) in nature is because it is an alkali metal, and therefore tends to bond with other elements rather than be alone.
If an element is chemically active what is the state of its outer electron shell?
The key to "happiness" for an atom is a full outer electron shell. (The outer electron shell is called the valence shell.) There are two conditions that cause a shell not to be full. Either it has only an electron or two (or three) in the outer electron shell or it's short an electron or two in that outer shell. The direct answer to the question is that if an element is chemically active, its outer electron shell is incomplete or is not full.
Is F more active than Cl?
They are both from the same group, yes. But F is above Cl so it means that the F's valence shell is nearer the nucleus (or at "lower level") than the valence shell in Cl, which causes F to have more effective nuclear charge. This fact explains the more electron affinity* in F in relation to Cl and therefore F is more reactive. * - electron affinity refers to a free atom. electronegativity refers to an atom in a molecule.
What is group one on the periodic table?
group #1 on the periodic table is called alkali metals, has one valence electron, and is the most active metal group.
What type of metals such as sodium have a single valence electron and are very active?
The alkali metals (lithium, sodium, potassium, rubidium, caesium, and francium) all have a single valence electron and tend to be very reactive. Note that hydrogen also has a single valence electron and is very reactive but it does not become metallic except at very, very, very low temperatures.or very, very, very high pressures (at least theory predicts it would be).
Why are group 2 elements more reactive as the group descends?
I believe because they are less reactive but more stable so it evens out and it makes it so the the less reactive it is the more stable and a better chance for that electron configuration to become more stable and less reactive so that it can build on to something bigger and better.
