True
An element with 11 protons will have atomic number 11, or sodium. If the element has 11 neutrons, then it has an atomic mass of 11+11 = 22. Therefore, the isotope Sodium-22 has 11 protons, neutrons, and electrons.
None. Francium is highly reactive, and highly radioactive. It doesn't exist free in nature.
Nitrogen gas is stable. However there are nitrogen compounds that are reactive.
Mercury is highly toxic (poisonous). The gas evaporating from the spilled liquid mercury is dangerous.
It is highly reflective and hard
Plasma
yes; HCL is
ionosphere
Hcl, it's ph is lower.
highly
They have broad emission lines of highly ionized elements.
The states of matter are:solidliquidgasplasma (hot highly ionized gas)
This state of matter is plasma: a highly ionized gas.
It is made up of a very hot gas, usually called "plasma" and considered a different state of matter than gas. The difference from a normal gas is that it is highly ionized.
highly ionized gas that glows in various colors: red, green, and blue in a TV.
You cannot know for sure withoutmore information. An electrically neutral sodium atom (sodium has at. no. 11) will have the same number of electrons as protons; atomic number tells you the number of protons, so this atom has 11 protons and would have 11 electrons if electrically neutral, however, if the atom is charged, it could have more or fewer electrons. Sodium atoms in stars are highly ionized and may have just a few if any any electrons.
