protons and electrons
well an atom itself cannot be subatomic, if subatomic means 'smaller than an atom'. an atom is neutral, since it will always contain the same number of protons and electrons, which are positively and negatively charged. The number of neutrons will not affect the electrical charge of an atom since it is neutrally charged.
It depends on the atom. An atom is made of 3 subatomic particles- a negatively charged electron, a positively charged proton, and a neutral neutron. If the number of electrons and the number of protons are different, then the atom has a net charge. If the number of electrons and the number of protons are the same, then the atom is said to be neutrally charged. Changing the number of neutrons affects the mass and therefore important traits of each atom, but does not affect its charge. Atoms that have a net charge are called 'ions.'
a neutrally charged atom has an equal number of both protons and neutrons, making the positive and negative charges the same. for example, in a neutrally charged atom, there would be 1 neutron and 1 proton.
A neutral atom has an equal balance of Protons and Electrons. Protons are positively charged whilst Electrons being opposites are negatively charged. To change a neutral atom to a positively-charged atom can be done by either removing an Electron from the atom, or by adding a Proton. Removing 1electron would make the number of Protons > number of Electrons by 1 making the charge on the neutral atom change to +1. Adding a Proton, the same effect occurs. To make a neutal atom negatively-charged simply do the reverse and make the Number of electrons > number of protons.
Same no. of protons/neutrons.
Of course it it is. An electron is negative, while a proton is positive. Therefore, by adding an electron, its the same thing as adding a negative. 0 - 1 = -1. So to cut to the chase, adding an electron makes the atom negative.
The number of an electron in a neutral atom is indicated by the atomic number, which is equal to the number of protons in the nucleus of the atom. In a neutral atom, the number of electrons is the same as the number of protons.
In the case of neutral atom, the number of positively charged protons and negatively charged electrons will be the same.
11 electrons in a neutrally charged atom of sodium . It is the same number as the number of protons and the Atomic Number. However, the sodium ion (NOT Atom) has lost one electron , so there are now 11 protons(+), and 10 electrons(-). Hence 11(+)10(-)= 1(+) Hence the sodium ion is written as 'Na(+)'.
Not much: it is what we call an ion. As a charged item, it will be drawn to any item that is differently charged to itself - Lacking an electron, it is positively charged, so it will be drawn to an item that is negatively charged (a surplus of electrons), neutrally charged (the right number of electrons), or even less-positively charged. As soon as an ion comes in contact with such an item, it will grab an electron from that. Be that item a larger atom or molecule, a spec of dust, a wall, or you. It will then be an ordinary, uncharged oxygen atom. What it touched will then be charged slightly differently, and will be drawn to another charged item, until everything is charged the same. So for an atom, being short an electron is not a big deal.
Each atom of an element has the same number of protons which is unique for that particular element ( = atom number in the periodic system)
Yes, an electrically neutral atom has the same number of protons and electrons. Protons have a positive charge, while electrons have a negative charge. When these charges are balanced, the atom as a whole is neutral.
