Technically, ANY atom could have "one electrons" or, as I suspect you mean to ask, one electron. In its uncharged state, a protium atom, also known as a hydrogen-1 atom, is the only atom posessing a single electron, but in theory any atom could have any number of its electrons stripped off, and be left with only one (or even none).

The atomic number of an element tells you the amount of of electrons. In oxygen, symbol 'O', there are 8 electrons since the atomic number is 8. For example, the atomic number of Hydrogen is 1, so there is 1 electron in a Hydrogen atom.
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
The element with 55 electrons is Caesium (Cs). Caesium is an Alkali Metal in Period 6 of the Periodic Table. It has the atomic number 55. It has 55 electrons in 6 shells with 1 electron in the outer shell.
Iron (Fe) is the element that has 4 unpaired electrons in its electron configuration.

The velence electron will vary for element to element and can have 1 to 8 valence electrons.

To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
To determine the number of valence electrons for an element on the periodic table, you look at the group number of the element. The group number tells you how many valence electrons the element has.

Hydrogen is a metal element. There are 1 electrons in a single atom.
Hydrogen is a non metal element. There are 1 electrons in a single atom.
The element with 2 electrons and a charge of -1 is helium. It typically has a charge of 0, but can gain an extra electron to have a -1 charge.
To determine the number of valence electrons in an element, you look at the group number on the periodic table. The group number tells you how many valence electrons an element has. For example, elements in group 1 have 1 valence electron, elements in group 2 have 2 valence electrons, and so on.
IT is the electrons on element IT is the electrons on element
51 protons defines the element as antimony (Sb). It normally has 51 electrons, so with 52 electrons, it would be Sb with a 1- charge.
To identify the valence electrons of an element on the periodic table, look at the group number of the element. The group number indicates the number of valence electrons. For example, elements in Group 1 have 1 valence electron, elements in Group 2 have 2 valence electrons, and so on.
