What is the charge on an atom after it loses an electron during the formation of a bond?

Chemistry

Sphinxa [80]3 years ago

I believe the charge is positive as losing an electron suggests that the atom lost a negative charge, leaving it with more positive than negative.

I haven't taken this in a few years very sorry if i'm wrong tho.

Answer:

Its charge is positive

Explanation:

A neutral atom has the same amount of proton and electrons, so the charges are cancelled. When an atom loses an electron, its charge becomes positive and its exact charge is 1+. Thus, it is formatted a cation that may interact with an anion (an atom who receives an electron) to form an ionic bond.

Bare in mind that electrons have a negative charge and protons have a positive charge.

NO LINKS PLEASE! Why does dye dropped into a cup of water eventually spread throughout the water?
Nezavi [6.7K]

Answer:

C

Explanation:

okay, you need to look at the structures of the particles of matter in the solid, liquid and gas.

  • particles in a solid are in fixed positions, where they can only vibrate in those positions ( take a look at ice, or rather, a brick)
  • liquids have very small or rather, no spaces between them, but they can slide or rub against each other, like people in a <em>really tight</em> crowd I guess
  • gas particles have very large spaces between them and they move randomly. these exibit what's called brownian motion.
  • since water particles (and all other liquid particles) have negligible spacings and limited movement, that allows the dye particles to move from a region of high concentration to that of a low concentration. the aim for this is for the mixture/solution to reach an equilibrium, that  is the mixture must get to a point where all regions have the same concentration of the dye.

you can refer to your coursebooks :)

correct where wrong please:)

What is the kinetic energy of the emitted electrons when cesium is exposed to UV rays of frequency 1.3×1015Hz?
Sonja [21]

Answer:

We know that

ħf = ф + Ekmax  

where  

ħ = planks constant = 6.626x10^-34 J s  

f = frequency of incident light = 1.3x10^15 /s (1 Hz =

1/s)

ф = work function of the cesium = 2.14 eV  

Ekmax = max  kinetic energy of the emmitted electron.  

We distinguish that:

1 eV = 1.602x10^-19 J

So:

2.14 eV x (1.602x10^-19 J / 1 eV) = 3.428x10^-19 J

So,

Ekmax = (6.626x10^-34 J s) x (1.3x10^15 / s) - 3.428x10^-19 J

= 8.6138x10^-19 J - 3.428x10^-19 J = 5.1858x10^-19 J  

Answer:

5.19x10^-19 J  

Kinetic energy:

In physics, the kinetic energy of an object is the energy that it owns due to its motion. It is defined as the work required accelerating a body of a given mass from rest to its specified velocity. Having expanded this energy during its acceleration, the body upholds this kinetic energy lest its speed changes.

How many moles of salt are in 13.8 g of sodium chloride?
Hoochie [10]

Answer: 0.24 moles

Explanation:

Molecular Mass of NaCl (23 + 35.5) = 58.5g

58.5g of Sodium Chloride -------> 1 mole of NaCl

∴ 13.8g of Sodium Chloride  ------>  1 ÷58.5 x  13.8 = 0.2358974  ≈    0.24moles

What is the mass of a magnesium block that measures 2.00 cm
skad [1K]

Answer:

m = 31.284 grams

Explanation:

Given that,

The dimension of a magnesium block is 2.00 cm  x 3.00 cm x 3.00 cm.

The density of magnesium is, d = 1.738 g/cm³

We need to find the mass of the magnesium block. We know that the density of an object is given by its mass per unit its volume. So,

d=\dfrac{m}{V}\\\\\text{Where m=mass}\\\\m=d\times V\\\\m=1.738\ g/cm^3\times (2\times 3\times 3)\ cm^3\\\\m=31.284\ \text{grams}

So, the mass of the block is 31.284 grams.
