Question

Atoms normally contain equal numbers of protons and electrons, thus they are electrically ( positive / negative / neutral ) . An electron is a (negatively / positively) charged particle. So if an atom loses an electron, it will then have an overall (negative / positive ) charge. If an atom were to gain an electron, it would have an overall (negative / positive ) charge. If a hydrogen atom loses its electron, it ends up with a (negative / positive ) charge. (This hydrogen ion is often referred to as a proton, as the entire structure of the atom is now simply the proton that is left in its nucleus) The atomic symbol for magnesium is How many protons does a magnesium atom have? How many neutrons? How many electrons? In the space below, draw a magnesium atom. Label the protons, neutrons, and place the electrons in orbitals with the correct number of electrons in each. Remember, the first orbital can take 2 electrons, the second can take 8 and the third can take 8.

00:01 An atom is the smallest unit of any matter present or is present in existence.

00:16 So let us find out certain properties of an atom.

00:20 So an atom has a nucleus, here nucleus denoted by n and is surrounded by orbitals in which electrons are present.

00:36 Now these electrons are negatively charged.

00:46 Here electrons denoted by e negative are negatively charged while the nucleus consists of two elements basically for two entities more of which is protons which have positive charge and neutrons which do not possess any charge.

01:25 Charge.

01:30 We have to remember that the number of electrons is always equal to number of protons in a normal state of an atom.

01:50 Let us move further with all this information to solve our questions.

01:56 Atoms normally contain equal number of protons and electrons, meaning protons here denoted by p, number of protons, is equal to number of protons.

02:06 Electrons and these have opposite charges so the positive charge and the negative charge.

02:13 So these two charges get negated because the same number of entities present negated.

02:23 This explains that the charge becomes neutral.

02:27 So our answer is that atoms normally contain equal number of protons and electrons, thus they are electrically neutral.

02:35 An electron has what kind of charge which is negative.

02:40 So an electron has negative charge.

02:43 So if an atom loses an electron, then it will have overall positive charge because the number of protons will not change.

02:52 But the number of electrons are changing.

02:54 So negative charge is reduced and positive charge will be there on the atom...
