Answer:

D equal numbers of protons and electrons​

Explanation:

An atom of an element will always contain equal number of protons and electrons.

Atoms are electrically neutral because the number of positive charges and negative charges within them are always equal.

  • An atom is the smallest indivisible particles of an element that takes part in a chemical reaction.
  • The positively charged particles within an atom are the protons.
  • The negatively charged particles within an atom are the electrons.

For;

 So number of protons = number of electrons within an atom.

The octet rule states that atoms will gain, lose, or share valence electrons to get a full outer shell (orbital). Explain in you
bezimeni [28]

Answer:

In covalent bonding, the octet rule is important because sharing electrons gives both atoms a full valence shell. As a result, each atom can consider the shared electrons to be part of its own valence shell.

Calculate the percent activity of the radioactive isotope strontium-89 remaining after 5 half-lives.
maria [59]
The answer to this question would be: 3.125%

Half-life is the time needed for a radioactive molecule to decay half of its mass. In this case, the strontium-89 is already gone past 5 half lives. Then, the percentage of the mass left after 5 half-lives should be:
100%*(1/2^5)= 100%/32=3..125%

Which of the following compounds would contain an electrostatic attraction as bonds between ions?
4vir4ik [10]

Answer:

iron sulfate

Explanation:

Electrostatic attraction as bonds between ions is characteristic of the electrovalent bond or the ionic bond

In this type of bond, there is electron transfer from one atom to another. The atom that looses electrons become positively charged while the atom that gains electrons becomes negatively charged.

In iron sulfate, there is electrostatic attraction between Fe II ions and sulphate ions, making iron sulfate an ionic compound.
