Answer:

Explanation:

A. The charge on an element is determined by the differences between the number of protons and electrons in an atom.

An atom will have no charges if the number of protons and electrons are the same.

  • When an atom loses or gains electrons, the number of electrons will either decrease or increase
  • if the number of electrons is more than the number of protons, the excess electrons is the charge on the atom. And this makes the atom become a negatively charged ion.
  • if the number of electrons is lesser than the number of protons, the deficient electrons makes the atom a positively charged ion. The number of electrons by which the atom is deficient makes the atom a positively charged ion.

Charge  = number of protons  - number of electrons

B. Electrons form the charges they do because with the charge, they become stable like the noble gases.

The desire of every atom is  to have stable electronic configuration like those of the noble gases.

A potassium atom with a configuration 2 8 8 1 will prefer to lose an electron to become an Argon atom making the ion stable.

What happens when atoms bonds?​
jok3333 [9.3K]
Atoms form chemical bonds to make their outer electron shells more stable. ... An ionic bond, where one atom essentially donates an electron to another, forms when one atom becomes stable by losing its outer electrons and the other atoms become stable (usually by filling its valence shell) by gaining the electrons.

Nikolay [14]

Answer:

(-1) is the slope of a graph of In(y+3) on the vertical axis versus In(x-2) on the horizontal axis.

Explanation:

\frac{(y+3)}{2} = \frac{b}{(x-2)}

Taking natural logarithm on both the sides:

\ln [(y+3)]-\ln[2]=\ln [b]-\ln [(x-2)]

\ln [(y+3)]=\ln[2]+\ln [b]-\ln [(x-2)]

\ln [(y+3)]=\ln {[2\times b]-\ln [(x-2)]

Slope intercept form is generally given as:

y=mx+c

m = slope, c  = intercept on y axis or vertical axis

On rearranging equation:

\ln [(y+3)]=(-1)\times \ln [(x-2)]+\ln {2b}

y = ln [(y+3)], x = ln [(x-2)], m=-1 , c  = ln 2b

(-1) is the slope of a graph of In(y+3) on the vertical axis versus In(x-2) on the horizontal axis.
