Mendeleev positioned elements in the periodic table in increasing order of their atomic numbers, such that elements having identical chemical properties and characteristics plunge into the same group.

What is Mendeleev's periodic table called?

In order to represent similarities and patterns in the behavior of elements, Mendeleev created the periodic table, which is an arrangement of elements in an increasing atomic mass order in tablet form.
Mendeleev stated that "Element characteristics are a periodic function of their atomic weight" in his renowned periodic law.
The Periodic Table of Mendeleev is a table that Mendeleev created to list elements in the order of their atomic weights.

Mendeleev discovered that there were two elements with atomic weights between 65.2 and 75 because he found it very satisfying that the properties of the elements were more similar and closer to this level.
He also imagined having other elements with possessions similar to those of these other elements.
In the periodic table, he left a blank for these two elements until they were finally discovered in their true existence.

Indicates which of the following radical chemical species and explains why

Zina [86]

Answer is: (CH3)C.
Carbon has four bonds in organic compound.
1) in (CH3)CH, carbon has four single bonds, one with hydrogen and three witn methyl group (CH₃), so he is not radical.
2) in (CH3)C, carbon has three single bonds and one free electron.
3) in (CH3)C+, carbon has three single bonds and no free electrons, he is carbocation, not radical.

How many grams of calcium chloride will be produced when 29.0 g of calcium carbonate is combined with 15.0 g of hydrochloric aci

horsena [70]

Answer:

22.7 g of CaCl₂ are produced in the reaction

Explanation:

This is the reaction:

CaCO₃ + 2HCl → CaCl₂ + CO₂ + H₂O

Now, let's determine the limiting reactant.

Let's divide the mass between the molar mass, to find out moles of each reactant.

29 g / 100.08 g/m = 0.289 of carbonate

15 g / 36.45 g/m = 0.411 of acid

1 mol of carbonate must react with 2 moles of acid

0.289 moles of carbonate will react with the double of moles (0.578)

I only have 0.411 of HCl, so the acid is the limiting reactant.

Ratio is 2:1, so I will produce the half of moles, of salt.

0.411 / 2 = 0.205 moles of CaCl₂

Mol . molar mass = mass → 0.205 m . 110.98 g/m = 22.7 g

as the elements period 3 are considered in order of increasing atomic number, the number of principal energy levels in each succ

Diano4ka-milaya [45]

Answer:

stay the same.

Explanation: Period 3 consists of the full 1s, 2s, and 2p electron orbitals, plus the 3s and 3p valence orbitals, which are filled with a total of 8 more electrons as we move from left (Na) to the far right (Ar):

Na: 1s2 2s2 2p6 3s1

Ar: s2 2s2 2p6 3s2 3p6

As we move from left to right, and ignoring the already-filled 1s, 2s, and 2p orbitals, the period three starting and ending elements have the following:

Na: 3s1

Ar: 3s2, 3p6

All the new electrons electrons filled the third energy level (3s and 3p). So the energy level does not change, just the orbitals.
