What is the number of neutrons in an atom with atomic mass of 35 and three energy levels and 7 valence electrons?
There are 18 neutrons. If the valence level has 7 electrons, that means the first is full, and always has 2(unless its hydrogen which has 1) and the second will be filled with 8 making 17 total. Since the electrons always equal protons we know there are 17 protons. Since Atomic Mass is protons plus neutrons, and atomic mass is 35 we minus 17 form 35 and have 18.

Do valence electrons determine the atomic mass?
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.
Which electrons in an atomic take part in chemical bonding and what are they called?
outer energy level electrons... called valence electrons
What is the word for the definition electrons in the outermost energy level of an atom?
valence electrons are the electrons in the outermost energy level
What element has 6 valence electrons in the 4th energy level?
This element is caesium (Cs), with the atomic number 56.
The element with 4 energy levels and 4 valence electrons is Titanium right?
That is correct. Titanium has 22 electrons, and its highest full orbital is 4s and the 3d is partially filled with 2 electrons. So Titanium is 1s22s22p63s23p64s23d2
Do valence electrons determine the atomic mass?
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.
How do you find the number of non-valence electrons?
To find the number of non-valence electrons in an atom, you first need to determine the total number of electrons in the atom by looking at its atomic number on the periodic table. Next, subtract the number of valence electrons, which are the electrons in the outermost energy level of the atom, from the total number of electrons. The remaining electrons, which are not in the outermost energy level, are the non-valence electrons.
How many valence electrons would an element with atomic number 56 have?
The element with atomic number 56 is barium, a group 2 alkaline earth metal. Its atoms have two valence electrons in the 6s sublevel.
What is an element with 7 valence electrons and 4 energy levels?
This element is likely chlorine (Cl), which has 7 valence electrons and 3 filled energy levels with a partially filled 4th energy level.
Which electrons in an atomic take part in chemical bonding and what are they called?

How many valence electrons would an element with an atomic number of 14 have?
An element with an atomic number of 14, such as silicon, would have 4 valence electrons. Valence electrons are the electrons in the outermost energy level of an atom, which corresponds to the group number of the element on the periodic table.
How many electrons on the outermost energy level of atomic number 10?
Atomic number 10 corresponds to neon. Neon has 10 electrons, with 2 electrons in the innermost energy level and 8 electrons in the outermost energy level.
What element has 118 and 8 valence electrons?
The element with atomic number 118 and 8 valence electrons is oganesson (Og). Oganesson belongs to the noble gas group and has a complete outer shell of valence electrons, making it stable and unreactive.
How does the energy of the core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
What element has 2 valence electrons and 4 protons?
The element with 2 valence electrons and 4 protons is beryllium. Beryllium has an atomic number of 4, indicating it has 4 protons in its nucleus. The valence electrons are the outermost electrons in an atom, and beryllium has 2 valence electrons in its outer energy level.
How does the energy of core electrons compare with the energy of valence electrons?
The energy of the valence electrons is greater than the energy of the core electrons.
What determines an elements property?
Chemical properties of an element determine by the number of electron
