Which block on the periodic table contains the actinide series of elements?

1 answer:

4 0

F BLOCK is the block on the period table that contains the actinide series of elements.

Actinide series of elements are two rows under the periodic table which include Lanthanide series and Actinide series. These are all radioactive elements and all of these are not not found in nature. All these are included in F block element.

What is the concentration, in m/v percent, of a solution prepared from 50 g NaCl and 2.5 L of solution?

Serjik [45]

When we convert the given mass in grams and volume in liters to m/v percent, we recall that m/v percent is expressed as grams/100 milliliters. In this case the expression becomes (50 grams/ 2500 L)*(0.1L/100ml), that is equal to 0.002 grams/ 100 mL. Hence the the concentration is equal to 0.2 m/v percent.

An atom of chlorine with a mass number of 37 contains __ protons and __ neutrons.

Natasha2012 [34]

Answer:

Its in the Explanation

Explanation:

Here's what I got.

Aluminium-27 is an isotope of aluminium characterized by the fact that is has a mass number equal to

Now, an atom's mass number tells you the total number of protons and of neutrons that atom has in its nucleus. Since you're dealing with an isotope of aluminum, it follows that this atom must have the exact same number of protons in its nucleus.

The number of protons an atom has in its nucleus is given by the atomic number. A quick looks in the periodic table will show that aluminum has an atomic number equal to

This means that any atom that is an isotope of aluminum will have

protons in its nucleus.

Since you're dealing with a neutral atom, the number of electrons that surround the nucleus must be equal to the number of protons found in the nucleus.

Therefore, the aluminium-27 isotope will have

electrons surrounding its nucleus.

Finally, use the known mass number to determine how many neutrons you have

mass number

no. of protons

no. of neutrons

no. of neutrons = 27 − 13 = 14

Your welcome :)
