1)The properties of the first member of each group are slightly different from the rest of the members.
2)The first member of all the group is supposed to be less metallic in nature.
3)Due to the small size of the first member of each group it is considered that it is more electro_negative as compare to its group members because of its small size.
4)The atomic size increases down the group but this trend is not successful in transition elements .

In what years did Dmitri Mendeleev research?
Dmitri Mendeleev performed his research during the year 1847.
Which two elements on the periodic table would have been placed in different groups in Moseley's periodic table but not in Mendeleev's?
Let us be quite clear about this -- Mendeleev's periodic table (1871 version) was perfectly accurate.There were two or three anomalies in it. Tellurium was placed in a group with selenium and sulfur leaving iodine to go with bromine and chlorine. Mendeleev spent 20 years arguing (falsely) that the experimentally determined atomic weight of tellurium had to be wrong. Nickel and cobalt were assigned identical atomic weights to allow nickel to be put in a family with palladium and platinum, and cobalt with rhodium and iridium. There was evidence at the time that nickel was slightly lower on the atomic weight scale, but Mendeleev's assignment of atomic weights was within the experimental error. And finally argon and potassium were hugely out of order on the atomic weight scale, because it was very obvious that argon was a noble gas and potassium an alkali metal. But argon was only discovered in 1894, and Mendeleev was reluctant to even accept the noble gases as elements, let alone deal with that particular anomaly. So the atomic number scale that was uncovered by Moseley's work cleared up these anomalies, but did not lead to any changes in the periodic table.
How did Mendeleev predict the properties of silicon?
Mendeleev did not predict the properties of silicon.
What did Mendeleev develop?
Mendeleev was a Russian chemist who organized the periodic table.
When was Mendeleev born?
Dimitri Mendeleev was born on February 8th, 1834.
What types of anomalies are found in relational database?
There are 3types 1) Update Anomalies 2) Insertion Anomalies 3) Deletion Anomalies
When was The Anomalies created?
The Anomalies was created in 2003.
What are three anomalies that are likely result to data redundancy?
The three types of anomalies likely to show up are: Insertion, Deletion, and Update anomalies.
How many pages does The Anomalies have?
The Vanishings has 160 pages.
Is there any evidence or proof of anomalies on the moon?
That depends what type of anomalies you are looking for.
When was The Anomalies of Artificial Origin created?
The Anomalies of Artificial Origin was created in 2012-01.
What nationality was Dmitri Mendeleev?
He was Russian
What is Doctor Mendeleev's full name?
Dmitri Mendeleev
What are the anomalies of Moseley's periodic table?
The periodic table after Moseley is logical and without physical anomalies.
Why is anomalies required in database?
Anomalies are not required in a database. An anomaly is a inconsistency or a problem. A well designed database should not have any anomalies. If there are some, they can cause problems for the users and for the reliability and efficiency of the database.
In what years did Dmitri Mendeleev research?
Dmitri Mendeleev performed his research during the year 1847.
