Who invented the Bohr model and what does it look like?
Niels Bohr created this model; electrons move around the positive atomic nucleus.
Why does an atom that has lost an electron have a positive charge?
Every atom has a positively charged nucleus containing protons, each with a 1+ charge. Electrons, each with a -1 charge surround the nucleus. In a neutral atom the number of electrons is equal to the number of protons, so there is no net charge. If an atom loses electrons it will have more protons than electrons resulting in an overall positive charge. For example, a neutral magnesium atom has 12 protons and 12 electrons, resulting in an ion with 12 protons and 10 electrons. Since there are two more protons than electrons in this ion, the overall charge is 2+
When was Table of the Elements created?
Table of the Elements was created in 1993.
What role did supernova play in creating the natural elements?
It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.It is precisely the supernovae that created those elements and dispersed them into space.
What is a chemical bond and how is it created?
There are several types of chemical bonds. An ionic bond, for example is when two elements have opposite charges are attracted to each other. A positive and a negative charge or a negative and a positive charge can be attracted to each other. If a positive and a positive are attracted to each other or a negative and a negative are attracted, that's considered an immoral bond.

Current flows from plus ve to -ve or-ve to plus ve?
There are two ways to look at current. Conventional current (measured in amps) flows from positive to negative. This model works for the vast majority of electrical engineering purposes. However, current is created by the movement of electrons. Electrons have a negative charge so electrons moving in one direction will give rise to conventional current in the opposite direction. Therefore, although current flows from positive to negative, electrons flow from negative to positive.
What happens when charging by rubbing?
Static electricity is the result of creating a charge by rubbing two objects together. The positively charged objected with accepted electrons from the negatively charged item giving it an electric charge.
What is meant by a shared or lose pair of electrons in covalent bonding?
This means that when a compound is created, the elements create bonds in order for electrons to be shared equally. Every element wants to have a full octet in order to be stable. To complete this, both elements pull at the electron(s), and it gravitates towards each element.
When was A Positive created?
A Positive was created in 1998.
Which subatomic particle is involved in chemical bonds?
Electrons are either transferred between atoms to form ionic bonds or shared between atoms to form covalent bonds. Either way, bonds are formed through electrons.
