What is NS and NP in chemistry?
The p sublevel always fills after the s sublevel of a given principal energy level. Therefore, the general electron configuration for an element in the p-block is ns2np1-6. For example, the electron configuration of elements in Group 13 is ns2np1, the configuration of elements in Group 15 is ns2np3, and so on.
Which element is found in a family with the electron configuration ns2np3?
nitrogen family
What group in the periodic table has the valence shell configuration ns2np3?
valence shell electron configuration of ns2np3 are present in group 15 elements eg: N, P ,Al etc. ‘5’ superscripts indicates there are 5 valence electrons belonging to Group VA elements.
What are Group 5 elements called?
vanadium group
Which group will have an electron configuration that ends in ns1?
groups 1A-7A are called the meaning that the s and p sublevels of their outermost principal energy levels are only partially filled with electrons. all elements in this group have an electron configuration ending in ns1.
Why does the S block span two groups?
Why does the s-block span two groups of elements? Because s orbitals hold two electrons at most. Because the three p orbitals can hold a maximum of six electrons.
Which elements tend to gain or lose electrons?
Metals tend to lose electrons and non-metals tend to gain electrons, so in reactions involving these two groups, there is electron transfer from the metal to the non-metal. The metal is oxidized and the non-metal is reduced. An example of this is the reaction between the metal, sodium, and the non-metal, chlorine.
Which is the halogen that is in period 5?
fluorine
Is Iodine a period 5 halogen?
Group 7A — The Halogens. Group 7A (or VIIA) of the periodic table are the halogens: fluorine (F), chlorine (Cl), bromine (Br), iodine (I), and astatine (At). The name “halogen” means “salt former”, derived from the Greek words halo- (“salt”) and -gen (“formation”).
What is the period 4 halogen?
Bromine (Br) is an element in group 17 (halogen).
Is a noble gas found in the 5th period?
Nitrogen (N) is a noble gas located in period 5. Bromine (Br) is a halogen located in period 4. 8 Noble Gas Notation This is the most common notation to find and the easiest to write.
Which gas does not exist in air?
– Therefore Radium is not a noble gas and it is not present in the atmosphere. So, the correct answer is “Option B”. Note: Radium is not available in nature because it is prepared from a radioactive decay of other radioactive elements.
What does K and KR have in common?
Potassium (K) and Krypton (Kr) are in the same group, so they have the same number of valence electrons. Potassium (K) and Krypton (Kr) are in the same group, so they have the same number of valence electrons. Potassium is more reactive, because it has less electron shells than Krypton.
What do be Mg have in common?
They are beryllium (Be), magnesium (Mg), calcium (Ca), strontium (Sr), barium (Ba), and radium (Ra). The elements have very similar properties: they are all shiny, silvery-white, somewhat reactive metals at standard temperature and pressure.
What element has 4shells?
Beryllium
What do group 0 elements have in common?
The group 0 elements are placed in the rightmost column of the periodic table. They are called the noble gases because they are all chemically unreactive (the term noble in chemistry signifies a lack of chemical reactivity). They are unreactive because their atoms have stable arrangements of electrons.
What is another name for Group 0 elements?
noble gases
What happens as you go down Group 0?
The density of group 0 noble gases increases down the group. The atomic radii of group 0 noble gases increase down the group. Atomic radii always increase down a group with increase in atomic number because extra electron shells are successively added.
Why does density increase down Group 0?
The density increases as you go down the group. As the atoms get bigger, they get heavier, and so you have an increasing mass in the same volume – the density goes up.
Does reactivity increase down Group 0?
All elements in group 0 are un-reactive(have eight electrons in the outer shell) and gases. boiling points of the gases increase down the group. Group 1 elements react vigorously with water and make hydrogen.
Why do Group 7 elements get less reactive as you go down?
Reactivity decreases down the group. This is because group 7 elements react by gaining an electron. As you move down the group, the amount of electron shielding increases, meaning that the electron is less attracted to the nucleus.
Does reactivity increase down a group?
Reactivity Trends Metal reactivity increases down a group because as nuclear shielding increases and the nucleus’ hold on the valence electron weakens, therefore it is easier to remove valence electrons.
Why does reactivity increase as you go down Group 1?
All group 1 metals have one electron in its outer shell. As we go down the group, the atom gets bigger. Therefore, the attraction between the nucleus and the last electron gets weaker. This makes it easier for the atom to give up the electron which increases its reactivity.
Why does reactivity increase down Group 1 but up Group 7?
Why do halogens get more reactive going upwards in group 7? Halogens from bromide to fluorine get more reactive because the force of attraction between the nucleus (core) and the outer electron get stronger as you go up group 7 elements. As you go up group 7 (the halogens), again the elements get more reactive.
Is Group 1 or Group 2 more reactive?
The outermost electrons of the alkaline earth metals (group 2) are more difficult to remove than the outer electron of the alkali metals, leading to the group 2 metals being less reactive than those in group 1.
Why is group 0 relatively unreactive?
When elements react, their atoms complete their outer shells by losing, gaining, or sharing electrons . Atoms of group 0 elements already have stable arrangements of electrons. This means that they have no tendency to lose, gain, or share electrons. This is why the noble gases are unreactive.
Are Group 7 elements reactive?
The halogens are the elements found in the second-to-last group of the Periodic Table. They all have seven electrons in their outer shell and since they need only one more to complete their octet they are fairly reactive.
