Explanation:
This is because the atom that ’donate’ the electrons and the one that ‘accepts’ the electrons – to become ions – will share an electrostatic association and form an ionic bond. So in reality, the atoms are only transferring electrons between themselves rather than “losing and gaining” electrons. When the ionic bonds are broken, such as in chemical reactions, the atoms go back to neutral (regain their electrons) and form new associations with other atoms to form new compounds.

Answer:
Approximately 12,500 SARS-CoV-2 viruses
Explanation:
According to this question, the period described is 1mm in diameter. Since 1millimetre(mm) is 1000metre(m), this means that the period is 0.001m in diameter.
Also, the SARS-CoV-2 virus has a diameter of 80 nm (1nm = 10^9m).
Since 10^6nanometres (nm) or 1,000,000nm makes 1millimeter (mm), 80nm of the virus will be:
= 80/1,000,000
= 0.000080mm or 8 × 10^-5mm
To calculate how many of the SARS-CoV-2 virus will fit into the period, we divide the diameter of the period (in mm) by the diameter of the virus (in mm).
That is; 1 ÷ 8 × 10^-5
= 1/8 × 10^5
= 0.125 × 100,000
= 12,500
Therefore, approximately 12500 SARS-CoV-2 viruses will fit in the period.
