How many valance electrons does a neutral atom of silicon have?
That neutral silicon atom has four electrons in its valence shell.
What must a neutral atom with four protons contain?
A neutral atom must contain an equal number of electrons because it is a neutral atom.
What must a neutral atom with four contain?
4 electrons
How many electrons would you expect to find in a neutral atom containing three protons and four neutrons?
3
How many electrons does a neutral atom with four protons contan?
Berylium with an electron structure of 1s22s2 has 4 electrons.
How many electrons does a carbon atom have in its outer energy level?
There are four electrons in the outer or valence shell of a neutral carbon atom.
Would an atom with 3 electrons in level M tend to gain or lose electrons?
That depends on the element. Any such atom with more than four protons will gain electrons to become electrically neutral. If that atoms has four protons (beryllium) then it will be able to form a stable ion with two electrons. If it is left with three electrons it will either gain an electron to form a neutral atom or, if in the presence of an oxidizing substance, lose an electron to form an ion. If the atom has three protons (lithium) it will form a stable, neutral atom with three electrons but will lose one electron when it reacts to form a stable ion. If that atom has two protons (helium) then it will only be stable with two electrons and will gain or lose electrons accordingly to maintain that number. If the atom has one proton (hydrogen) then it will tend to share electrons rather than gaining or losing them. It forms a neutral atom with one electron but can form an ion with two. It has no stable configuration with three electrons.
How many electrons are in the third principal level of a chromium atom?
There are eight electrons in the third level of a chromium atom.There are four level in the chromium atom, and the fourth level, unfilled, contains 6 out of 18 electrons, in the neutral, non-ionized atom.
How many electrons are in a beryllium ion?
The beryllium atom has 4 electrons. As with all other elements, Beryllium atoms are most stable when they have a full outer shell of electrons. Since the neutral electron configuration of the beryllium element atom is 1s2 2s2 (total of 4 electrons) the atom either needs to pick up another six electrons, thereby becoming 1s2 2s2 2p6, or lose two electrons to become 1s2.
How do you determine how many electrons are in an element?
Number of Protons=Atomic Number. In a neutral atom (any atom listed in the periodic table), the number of protons equals the number of electrons. This is because a proton has a +1 charge and an electron has a -1 charge. Example: Carbon has an atomic number of 6. A neutral carbon atom therefore has 6 protons and 6 electrons. Unrelated, but sort of more relevant, carbon has four valence electrons. If the carbon was written like so: C+, then the carbon would have a positive 1 charge and would have one less electron than the neutral carbon. The number of protons would remain the same at 6, but the total number of electrons would be 5.
Nitrogen atoms have 7 protons how many electrons are in an ion with a charge of plus 5?
A nitrogen atom has 7 protons and 7 electrons as it is electrically neutral. (An atom always has same number of protons and electrons)
A molecule with a bent shape with a bond angle of 104.5 would have how many unshared electrons around the central atom Count electrons not electron pairs?
four electrons . four electrons .
