LI ; lithium is an example with 3 protons.
acid
Lithium.
The alkali metal. The alkali metal has less protons in the nucleus compared to the halogen in the same period and therefore exerts a relatively smaller attractive force on the outer-most shell electrons, enabling them to stray further away.
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.
The highly active metal with 1 valence electron and 55 protons in the nucleus is cesium (Cs). It belongs to the alkali metals group and is known for its high reactivity, especially with water. Cesium's atomic number is 55, indicating it has 55 protons, and its single valence electron contributes to its vigorous chemical behavior.
acid
Lithium.
It is calcium.
The alkali metal. The alkali metal has less protons in the nucleus compared to the halogen in the same period and therefore exerts a relatively smaller attractive force on the outer-most shell electrons, enabling them to stray further away.
The alkali metal with 76 fewer electrons than francium is lithium. Francium has 87 electrons, so lithium, which has 3 electrons, has 76 fewer electrons than francium.
Protons are found in the nucleus of an atom, not around the nucleus as electrons are.
No. sodium is an alkali metal element that has 12 neutrons, 11 protons and 11 electrons in it's compositional make up.
potassium
Sodium element contain 11 protons. It is a alkali metal.
If you could see an alkali metal atom, it would have a nucleus containing protons and neutrons, and an electron cloud containing electrons. In the electron cloud, the highest energy level would contain only one electron.
Lithium has the lowest number of protons of any metal: 3. Hydrogen an helium have fewer protons bu they are not metals.
No, protons are not free to drift in metals. It is the electrons that are free to move in metal conductors, creating an electric current. Protons are located within the atomic nucleus and are not mobile in the same way as electrons.
