Explain why hydrogen is not included in group 1 in most versions of the modern periodic table?

It might be included in group 1 (one). Hydrogen is a special case, because even though it does have the defining characteristic of all group 1 elements, which is that it has one valence electron, it is physically very different from all the other group 1 elements. Hydrogen (at normal temperatures and pressures) is a gas, and all the other group 1 elements are solid metals. As a result, some forms of the Periodic Table show hydrogen above the rest of the table, in its own special place. However, it does belong in group 1.

Hydrogen is regarded as a rogue element in the periodic table explain?
It is an incredibly small atom which gives it several uniqque properites. 1. It can ionise to leave a single proton with a very small radius (acid base reactions) (Please add more)
How do you explain how the periodic table set up?
The periodic table contains 18 columns known as groups and 7 rows known as periods. The properties of the elements are found to be periodic when arranged in order of increasing atomic number.
Who used planck's idea of quantization to explain the line spectrum of hydrogen?
Bohr
Explain why chlorine gas is collected at a slower rate than hydrogen?
Because the weight / density of chlorine is more than hydrogen. Hence the rate of displacement will be less than that of hydrogen.
Explain what happens when two hydrogen atoms bond?
Each hydrogen atom has 1 electron. When two hydrogen atoms combine they each share that electron with the other hydrogen atom, creating a covalent bond and a molecule of H2.
Why are carbon and hydrogen in the reactivity series?
"Carbon and hydrogen are often included in the reactivity series even though they are non-metals. Carbon is included because this helps to explain what happens in the extraction of iron in a blast furnace. Hydrogen is included because any metal below it will not react with dilute acids."http://www.frankswebspace.org.uk/ScienceAndMaths/chemistry/reactivitySeries.htm
Did Bohr's model of the atom explain hydrogen's flammability?
Bohr's model of the atom doesn't explain hydrogen's flammability.
How does atomic number explain the arrangement of the periodic table?
According to the modern periodic table "Elements are the periodic function of their atomic number".They are arranged in increasing atomic no. in the periodic table.
What is the purpose of periodic performance reports in real estate?
Explain the purpose of a periodic performance report (two benefits)
Explain why the table of elements is periodic?
because of the electron configuration are different
What is water explain?
Water is a compound of hydrogen and oxygen.

Some say the periodic table is read like a book Explain how you read the periodic table and how this can give you information about elements in the table?
you read it from left to right
Does the periodic table explain the shell model or does the shell model explain the periodic table?
The shell model explains the organization of the periodic table. The elements in the first period have electrons in the first shell; the elements in the second period have electrons in the first two shells; the elements in the third period have electrons in the first three shells; and so on.
