∙ 14y agoA "normal" Hydrogen atom has 1 electron, 1 proton, and 1 neutron. Because atoms can lose electrons, it would be possible to encounter, say, a helium atom with one electron; however, atoms are more stable with two electrons than one, so it is unlikely that a helium atom would easily lose an electron.

Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
What is the mass of 1 electron?
1/1836 of an electron is the mass of an electron. It is so small they aren't even calculated in the Atomic Mass of an element
How many electron pairs are in CH3CFO?
This is a chemical element. You can find the how many electron in a single atom by using a periodic table.
What information can you get from electron dot diagram?
1. An electron dot diagram can show you that the symbols for an element surrounded by dots. Each dot stands for one valence electron.
What element gains 1 electron and attains the noble gas configuration of Xe?
xenon
Which element has 1 valence electron and is in period 1.?
The element with 1 electron in period 1 would be hydrogen.
What is the smallest element that maintains the properties of an element?
The smallest element on the Periodic Table is Hydrogen. It has only 1 electron in 1 electron shell and 1 proton in it's nucleus.
What element has 1 proton 1 neutron and 1 electron?
The element is hydrogen and the isotope is tritium (1H3)
Which element has only 1 electron and behaves like a alkali metal?
The element Hydrogen (H) has only 1 electron. When it loses it, it becomes the Ion H+.
What is the number of valence electrons the element hydrogen has?
One.Hydrogen has only 1 electron in total, and it is also a valence electron.
What element has 1 valence electron and 19 protons?
Potassium
Relative mass of electron?
1/1840 the mass if a hydrogen atom.
Which neutral atom of an element has 1 unpaired electron?
I'm pretty sure its hydrogen, since the is only 1 proton and 1 electron.
If an element has 1 valence electron what group is it in?
That element would be in the Alkali Metals (group one)
This element has the smallest atoms of all the elements?
Hydrogen has the smallest atoms of any element, as it has only 1 electron in 1 electron shell and 1 proton. This is why it's first on the Periodic Table.
What element has an electron configuration of 2 8 8 1?
Potassium.
What element contains 1 electron in its fifth energy level?
Rubidium
