A nucleus contains only positrons and neutrons, which have a positive and neutral charge, respectively. The electrons (with a negative charge) orbit around the nucleus. So, a nucleus in and of itself is positively charged.
The magnesium atom is electrically neutral. It has 12 protons in the nucleus, which are positively charged, and 12 electrons surrounding the nucleus, which are negatively charged. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
An atom is electrically neutral because it has the same number of protons (positively charged) in its nucleus as electrons (negatively charged) surrounding the nucleus. This balancing of positive and negative charges within the atom results in an overall neutral charge.
neutron
This is the neutron.
An atom is electrically neutral because it has an equal number of protons (positive charge) in the nucleus and electrons (negative charge) outside the nucleus. The positive and negative charges balance each other out, resulting in a net charge of zero for the atom.
Atoms are electrically neutral because they have an equal number of positively charged protons in the nucleus and negatively charged electrons surrounding the nucleus. The positive and negative charges balance each other out, resulting in an overall neutral charge for the atom.
In this scenario, the atom is electrically neutral. The positive charge of the nucleus is exactly balanced by the negative charges of the surrounding electrons, resulting in a stable and neutral atom.
The atomic nucleus is not neutral, it is positively charged (the exact charge depends upon the element in question; the hydrogen nucleus is +1, the helium nucleus is +2, etc). The atom as a whole is electrically neutral, unless it becomes ionized.
The atom is electrically neutral when the number of protons in the nucleus is equal to the number of electrons surrounding the nucleus. This balance of positive and negative charges results in no overall charge on the atom.
An atom is electrically neutral because it has an equal number of positively charged protons in its nucleus and negatively charged electrons orbiting the nucleus. The positive charge of the protons is balanced by the negative charge of the electrons, resulting in an overall neutral charge for the atom.
A neutral chlorine atom has 17 electrons. You can know this because chlorine's atomic number is 17, which is the number of protons in the nuclei of its atoms, and a neutral atom has equal numbers of electrons and protons.
A nucleus contains only positrons and neutrons, which have a positive and neutral charge, respectively. The electrons (with a negative charge) orbit around the nucleus. So, a nucleus in and of itself is positively charged.
