How were the elements in the first periodic table arranged?

Chemistry
1 answer:
Snezhnost [94]3 years ago
5 0

Based on atomic mass

Explanation:

Elements were arranged on the first periodic table based on their atomic masses.

The mass of an atom is made up of the mass of the nucleus which contains the protons and neutrons.

  • Dimitri Mendeleev was the first person credited for arranging elements periodically.
  • He was said to have been inspired while playing his game of solitaire on a train.
  • On his table, he left spaces for the atomic masses of elements not yet discovered.
  • Today, the periodic table is based on the atomic numbers of elements. This is the number of protons in an atom.

Help pleaseee!!!Please explain how evaporation condensation and precipitation are involved in the water cycle
gizmo_the_mogwai [7]

Answer: The water cycle shows the continuous movement of water within the Earth and atmosphere. ... Liquid water evaporates into water vapor, condenses to form clouds, and precipitates back to earth in the form of rain and snow. Water in different phases moves through the atmosphere (transportation).

35.0 mL of acid with an unknown concentration is titrated with 24.6 mL of 0.432 M base. What is the concentration of the acid? A
dusya [7]

Given:

35.0 mL of acid with an unknown concentration

24.6 mL of 0.432 M base

Required:

Concentration of the acid

Solution:

M1V1 = M2V2

M1 (35.0 mL of acid) = (0.432 M base) (24.6 mL of base)

V1 = (0.432 M base) (24.6 mL of base) / (35.0 mL of acid)

M1 = 0.304 M of acid

The atoms of Group 7A elements gain electrons when they form ions.<br><br> True<br> False
artcher [175]
Answer: True.

Explanation.

The group 7A is actually named group 17.

That group is the halogens: F, Cl, Br, I, At, and Ts (Ts is one of the last elements discovered).

Those elements have 7 valence electrons (notice that it is the same number as the second digit in 17).

The atoms with 7 valence electrons will "easily" gain one electron to get the configuration of the next noble gas (8 valence electrons). That is why these elements gain electrons to form ions.

When atoms gain electrons form anions (negative ions). For example: F(-), Cl(-), Br(-), I(-).
