What is the valence electrons of Na?
Sodium (Na) has one valence electron.
How many protons electrons and valence electrons does na have?
Sodium's atomic number is 11. To be neutral then, it must have 11 protons and 11 electrons. Since sodium is in group 1, it has 1 valence electron.
What is the number of valency electron in sodium or oxygen ion?
Sodium ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.
How can you use a periodic table to predict the number of valence electrons an element has without having to draw the Bohr diagram?
In general, except for the transition elements, the group number will tell you the number of valence electrons. For example, Na is in group 1 and has 1 valence electron. Cl is in group 7 and has 7 valence electrons.
Elements that have the same number of valence electrons are?
Elements that have the same number of valence electrons are found in the same group of the periodic table. For example, all elements in Group 1 (e.g. H, Li, Na) have 1 valence electron, while elements in Group 18 (e.g. He, Ne, Ar) have 8 valence electrons. Valence electrons determine an element's chemical properties and reactivity.

Sodium's atomic number is 11. To be neutral then, it must have 11 protons and 11 electrons. Since sodium is in group 1, it has 1 valence electron.
What are the elements that have the same number of valence electrons?
The elements that have the same number of valence electrons are located in a group.The group number from the Periodic Table relates to the number of electrons in the valence shell.For example, elements in group 1 (H, Na, Li, K, Rb, Cs, Fr) all have 1 valence electrons and elements in group 7 (Cl, F, I, Br) have 7 valence electrons in its outer shell.
What is the number of valency electron in sodium or oxygen ion?
Sodium ion (Na+) has 10 valence electrons and oxygen ion (O2-) has 8 valence electrons.

What don you notice about the number of valence electrons as you move from left to right across a row or the period in the periodic table na-mg-al-si-p-s-ci-ar?
The number of valence electrons increases by one as you move from left to right across a period in the periodic table. Sodium (Na) has 1 valence electron, magnesium (Mg) has 2 valence electrons, aluminum (Al) has 3 valence electrons, silicon (Si) has 4 valence electrons, phosphorus (P) has 5 valence electrons, sulfur (S) has 6 valence electrons, chlorine (Cl) has 7 valence electrons, and argon (Ar) has 8 valence electrons.
Of the periodic table of the elements out of Na Be V C N F and He which has the same valence electrons?
N and V have same number of valence electrons.The number of valence electrons is 5. V is a metal while N is a non metal.
What is Na neutral but Na charged?
Na is the chemical symbol for Sodium. Na charged is an ion, meaning the number of electrons in the atom differs relative to the charge; for instance, Na+ is missing one of its valence electrons and Na- has an additional electron.
How do you find number of valence electrons?
Take the atomic number then subtract the amount of valence electrons. Example: Number of non valence (inner) electrons in Sulfur: 16 (atomic number) - 6 (valence electrons) = 10 (valence or inner electrons)
What is the number of valence electrons in table salt?
Table salt is sodium chloride and have Na+ and Cl- ions. They have the electronic configuration of Ne and Ar respectively and both have 8 valence electrons.
What is the number of valence electrons for He?
Two valence electrons.
Elements that have the same number of valence electrons are?
Elements that have the same number of valence electrons are found in the same group of the periodic table. For example, all elements in Group 1 (e.g. H, Li, Na) have 1 valence electron, while elements in Group 18 (e.g. He, Ne, Ar) have 8 valence electrons.
