No, the valance electrons determine the charge, the atomic number is determined by the number of protons. Generally, electrons are equal to protons, but in ions it is different, so use protons.

∙ 10y agoValence is determined by the number of electrons in the outermost shell. It is the characteristic of how many electrons can participate in chemical bonds.
Atomic Mass is determined by the number of protons and neutrons in the nucleus.

Does the valence electrons equal the number of protons?
Rarely. The number of valence electrons of an element depends on it's position on the periodic table. Any given element can have between 1-8 valence electrons. The number of valence electrons increases left to right on the periodic table, while the number of protons, which determine the atomic mass and identity of an element, increase in general. Therefore the number of valence electrons can only equal the number of protons at the 8th element and below (neon).
What usually forms a covelent bond and has 5 valence electrons and has the highest atomic mass in its group?
Bismuth
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
How does an atom of sodium has a larger mass than a atom of neon. how is this possible when neon has so many more valence electrons?
sodium has more protons and neutrons. electrons have practically no mass, valence electrons are just outer orbital electrons. sodium has 11 protons, 11 electrons, and 12 neutrons. Mass is 23. neon has 10 protons, 10 electrons, and 10 neutrons. Mass is just 20. The neon atom has 10 protons and 10 neutrons for a mass number of 20. The sodium atom has 11 protons and 12 neutrons for a mass number of 23. The number of valence electrons has no bearing on mass number or atomic weight.
How many electrons are in the outer shell of an atom with the atomic mass of nineteen?
you cannot determine its electronic configuration through its atomic mass. atomic no is necessary. for this, check modern periodic table.
The tendency of an element to react chemically is closely related to what?
its Atomic Mass.

What can you predict an element from it's position in the periodic table?
how many electrons it has---how many valence electrons and how many levels of electrons. its Atomic Mass its atomic number
What can you predict about an element from its position in the period table?
how many electrons it has---how many valence electrons and how many levels of electrons. its atomic mass its atomic number
How you can determine the number of protons electrons and neutrons an atom has from an atom's mass number and its atomic number?
To determine the number of protons, look at the atomic number. The number of electrons is also the atomic number.To find the number of neutrons subtract the atomic number from the Atomic Mass number.
Which element is a metalloid with 4 valence electrons?
Germanium (Ge) Atomic Number- 32 Atomic Mass-72.59
What usually forms a covelent bond and has 5 valence electrons and has the highest atomic mass in its group?
Bismuth
What information can you gather knowing the atomic number and mass of an element?
If you know the atomic no. and atomic mass, then the no. of electrons, no. of protons and no. of neutrons can also be determined. Atomic No.=No. of electrons = No. of protons. No. of neutrons=Atomic mass-Atomic no. Also, by no. of electrons you can determine its valency and the no. of valence electrons.
How do you determine the numbers of the three types of particles in each atom?
In an atom, no. of protons = no. of electrons=atomic no. no. of neutrons=atomic mass-atomic no.
Is it true that the mass number can be used to determine the number of electrons in an atom?
no --- atomic number
What particles are added together to determine atomic mass?
The number of protons, neutrons and electrons.
How many valence electrons are there is aluminum-25?
Number of valence electrons depends on number of electrons in uncharged atom(= atomic number), not on mass number. Al has atomic number = 13 and it belongs to group 13( III A) of periodic table so it's uncharged atom has 3 valence electrons. But valence electrons in ions is different. No. of valence electrons in an ion = No. of valence electrons in uncharged atom + negative charge or - positive charge1. 1. for charges only their magnitude is taken i.e. if charge is +2 or -2 then 2 is taken and put in equation.
