Why give two reason why hydrogen should not be considered as group 1 element?

Hydrogen is a gas at room temperature, while all the other group 1 elements are solids, and hydrogen forms covalent bonds much more readily than any other group 1 element.

Which element can be substituted for hydrogen in organic compounds?
The element of hydrogen is one of the most widely seen and used in the world. If you are creating organic compounds and need to replace hydrogen you should use fluorine.
How do you find a mass mumber of an element?
The mass number is found directly beneath the Element Symbol. Hint: Hydrogen (H) has a mass of 1.00794 Each cube should look similar to this: 1 H 1.00794
What is the element with the most mass per nucleon?
The element has the lowest mass per nuclear particle is Iron, while hydrogen is the element with the highest mass per nuclear particle. Cause "nuclear particle" here means particles forming nucleus, like proton or neutron. Hydrogen has just one proton, and an atomic mass of 1.00794, it's mass per nuclear particle is also 1.00794. For heavier elements like Iron, they have higher atomic mass but also more particles in their nucleus. For instance, iron has 26 protons and 30 neutrons, and an atomic mass of 55.847, it's mass per nuclear particle should be 55.847/(26+30)<1, which is much smaller than that of hydrogen.
What is the only element in the periodic table that does not belong to a group?
It doesn't entirlely stand alone. there is no gap from hydrogen and the rest of the table. Hydrogen is just simply singular. It only has one proton. No neutron. One of a kind. even though I believe deutrium to be number 2 on the table rather than helium. And neutronium should be classified as element 0. Should be categorized in the periodic tables at all time.
What should atoms of the same element contain?
Every atom categorised within the same periodic element should contain the same atomic number, which represents the number of protons within the nucleus. Each element is unique in how many protons reside in one atom, for example all oxygen atoms would contain eight protons and hydrogen atoms would only contain one proton.
Which element can be substituted for hydrogen in organic compounds?
The element of hydrogen is one of the most widely seen and used in the world. If you are creating organic compounds and need to replace hydrogen you should use fluorine.
Why hydrogen considered as a good fuel?
Hydrogen has the highest calorific value, which should make it good fuel
Structure model of hydrogen gas?
H2 (the two should be a small subscript) - Hydrogen GasH - H (two hydrogens bonded together with a single bond between them), since hydrogen atom/element only has one valence electron to share with the other atom/element.
Why in lipids hydrogen and oxygen is not in the ratio 21?
Because there's no reason that should be true. The definition of "lipid" has nothing to do with the oxygen/hydrogen ratio.
What element is lightest the elements?
The lightest element of all should have the lightest atomic mass. It is hydrogen-1 isotope. This atom has only one proton and no neutrons.
Why volume of hydrogen should be twice the volume of oxygen formed?
no reason..cause formula for water is h2o
What is the metalloid element with the fewest number of protons?
If you look at the periodic table, the atomic number denotes the number of protons in the element. For example, the first element on the table is hydrogen, and it has one proton (the fewest). Element number two is helium, and it has two protons, etc.
What is the evidence that suggests that hydrogen should be in the first column of the periodic table?
Hydrogen is a unique element of the Periodic Table. Due to its similarities in properties it can be placed at the top of group 1A or 4A or 7A.
What element replaces hydrogen atoms when placed in water?
The element is sodium. Sodium atoms have a low electron affinity and will replace hydrogen atoms when placed into water. The reaction of sodium and water produces hydrogen gas that is ignited by the heat of the reaction. It should be noted that almost any element in the alkali and alkaline-earth groups will replaced hydrogen in water.
The formula for baking soda is NaHCO3 name the element in baking soda?
From the formula given, it appears that Sodium (Na), Hydrogen (H), Carbon (C) and Oxygen (O) are the elements which compose the compound baking soda. Although it should be noted that the Hydrogen, Carbon and Oxygen are in the form of Hydrogen Carbonate and serve as an anion which is not an element but a sort of molecule.
How is hydrogen an alterative energy source?
Since there are no significant amounts of free hydrogen, it should be considered more of an energy storage than an energy source. In other words, it takes energy to separate water into hydrogen and oxygen; you get that energy back when the hydrogen is burned.
How is the atomic mass of an element figured out?
The mass number is found directly beneath the Element Symbol. Hint: Hydrogen (H) has a mass of 1.00794 Each cube should look similar to this: 1 H 1.00794
