How does the electronic configuration of sodium shows the group and period in the periodic table?
The electronic configuration of sodium is [Ne]3s1. Sodium has one valence electron. And it belongs to group 1. The valence electron is in 3s orbitals and it tells that sodium is a s-block element and is in period 3.
What are three uses of Bases?
Bases have many uses. One extremely common base is sodium hydroxide, or lye. It is incredibly powerful, and is able to dissolve glass. It can be used to scrub carbon dioxide from the air, and a similar compound, lithium hydroxide, is used on the International Space Station to clean the air. Another common base, ammonium hydroxide, is used to clean up stains. Bleach (sodium hypochlorite) is also used for this purpose. Calcium hydroxide can be used to raise the pH of soil. This is used to change the color of certain flowers, such as hydrangeas. Bases can be used to neutralize acids, as seen in the baking soda-vinegar reaction. But this property can be put to use as a painkiller--bee and ant stings are acidic, and can be neutralized with a base like soap. They are used in motor oil to neutralize the acid that would corrode your engine block. They are an ingredient in soaps and detergents. They are used in toxic cleanups when acid has been spilled to neutralize the acid.
What are symbols for representative elements Na Mg Fe Ni Cl?
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and chlorine (Cl)
Which of the following are symbols for representative elements Na Mg Fe NiCl?
Representative elements belong to s and p block. The elements are Sodium (Na), Magnesium (Mg) and Chlorine (Cl).
Would you expect sodium sulphate or copper sulphate to be colourless?
Copper is a transition metal- these often give rise to colored salts. Sodium is an s block metal these are generally colorless. The reason is that transition metals ions have electrons in an outer d orbitals that can be excited to higher energy levels by visible light.
Give 5 examples of base?
Every hydroxide and carbonate of s-block elements excluding beryllium are alkali and several others are aluminium hydroxide and ammonia.
What is the state at room temp of sodium?
Sodium is a s block element. It is is a solid in room temperature.
Is sodium is a noble gas?
Sodium is a representative element belonging to group 1 (s block element)
What is the basic principle of charcoal block test?

Drugs that decrease membrane permeability to sodium are used as what?
Drugs that decrease membrane permeability to sodium are used as local anesthetics. These drugs block the sodium channels and prevent NA+ from entering the cell. NA+ influx is important to dipolarize the membrane.
Which element has mass number of 23?
Sodium is a metal element. Atomic mass of it is 23.
Can you shape sodium chloride so that it isn't in perfect cubes like it is when you hit a big block of it strongly?
Sculptures can be realized in salt.
Group number 1 on the periodic table is what?
Atomic number is based on protons in a atom. Hydrogen is in s block. Atomic number one is 1.Hydrogen is atomic number 1.
What is the electronic configuration of Na?
Sodium is atomic number 11 so it has 11 electrons. The electronic configuration would be 1s2 2s2 2p6 3s1.
