How many total electrons would lithium have if its electron configuration is 1s2 2s1?

Chemistry
1 answer:
Solnce55 [7]3 years ago
5 0

Answer:

How many electrons are there in the lithium ion?

The battery goes on and on and on.

Each element have an electron configuration in depending of the principle (Hund’s rule , etc).

So by their atomic number tend to indicate the number of protons that are equal in a number of electrons.

So the atomic number indicate the numbers of electrons.

Atoms have direct stability as such lithium tend to be located in group 1A and period 2.

Lithium have the atomic number of 3.

So naturally their protons/number of electrons are 3.

The electron configuration is (LI) 1s² 2s¹ or [He] 2s¹.

To archive stability as any noble gas element HE , Then the lithium will form an electron to form a Lithium ion which is Cation LI+.

So by it the lithium ion had 2 electrons.

during a rising tide, ocean waves often become larger. if the amplitude of a wave increases by a factor of 1.1, by how much does
Sergio039 [100]

Answer:

1.21 times

Explanation:

The energy of a wave is proportional to the square of the amplitude of the wave.

Mathematically:

E\propto A^2

where

E is the energy of the wave

A is its amplitude

In this problem, the amplitude of the wave increases by a factor of 1.1; it means that the new amplitude can be written as

A'=1.1 A

Therefore, this means that the energy of the wave increases by a factor:

E'\propto A'^2=(1.1 A)^2 = 1.1^2 A^2 =1.21 A^2 = 1.21 E

Therefore, the energy of the wave increases by a factor 1.21.

Chemistry, 50 points!!! Will also mark brainliest if you answer everything
olasank [31]

Answer:

1. 2Al + Cl2 = Al2Cl2

2 TiCl4 + 2Na = Ti + 2NaCl2

3. H2O2 = H2O + O2

4. Na2S + 2HCl = H2S + 2NaCl

5. Mg(OH)2 + 2HCl = MgCl2 + 2H2O

1. 3O2 = 2O3
