Helium is a neutral atom that has several isotopes and can become an ion.
Yes, since it has 2 protons (+), 2 electrons (-) and some neutrons (0).
Yes it is
yes
Helium atom has no charge as all atoms are electrically neutral. But the nuclear charge of helium is 2 as it has 2 protons in its nucleus.
An electrically neutral atom is one that has an equal number of protons and electrons.
Any atom is neutral in the normal state.After loss or gain of electrons an atom become electrically charged.
An atom has the same number of positive protons and negative electrons so the charges balance out to zero
Na+
The magnesium atom is electrically neutral.
Helium atom has no charge as all atoms are electrically neutral. But the nuclear charge of helium is 2 as it has 2 protons in its nucleus.
An electrically neutral atom is one that has an equal number of protons and electrons.
An electrically neutral atom has the same number of electrons as protons. Since protons have a positive change and electrons have a negative charge, when there is the same number of them, the charges cancel each other out. Example: Helium is neutral when it has 2 electrons, since it also has 2 protons.
All atoms are electrically neutral. If an atom gains or loses an electron, we call it an "ion" rather than an atom.
Because an electrically neutral atom has an equal number of protons and electrons.
Any atom is neutral in the normal state.After loss or gain of electrons an atom become electrically charged.
An atom has the same number of positive protons and negative electrons so the charges balance out to zero
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.
Na+
An alumimium atom is electrically neutral and it is an isotope of aluminum.
All ions differ from an electrically neutral atom in that they are missing or have gained one or more electrons. A S2- atom has 2 less electrons than a neutral atom.
