What else can I help you with?
What is the chemical symbol for an element whose atoms have 11 electrons?
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
What is an element whose atoms can form a covalent bonds with another atom of the same element called?
The answer expected here is non-metal, and examples are carbon, chlorine, sulfur phosphorus. Metals have metallic bonds. However there are compounds where atoms of a metallic element form covalent bonds to other atoms of the same element.
What element whose neutral atoms have ten neutrons?
The element with neutral atoms containing ten neutrons is neon. Neon has an atomic number of 10, so it always has 10 protons and 10 electrons.
What is the element in the fourth period whose atoms have the same number of electrons in their highest energy levels at that tins do?
The element in the fourth period with atoms that have the same number of electrons in their highest energy level as tin is germanium. Both tin and germanium are in the same group (Group 14) of the periodic table, so they have the same number of valence electrons.
A substance that contains the element whose atoms have 12 electrons indicate which element?
Magnesium atoms have 12 electrons.
What is the element in the fourth period whose atoms have the same number of electrons in their highest energy levels that tins atoms do?
bromine, i think
Which elements is less reactive an element whose atoms have seven valence electrons or an element whose atoms have eight valence electrons?
the element with seven valence electrons will be more reactive. The reason for this is that elements want to always want to have a full valence shell (they always want 8, like a noble gas). The element with eight valence electron is happy with its full shell and will not want to get rid of any electrons.
What is a form of an element whose atoms have the same number of protons but different numbers of electrons?
An atom with a different number of electrons is called an ion.
How many electrons are in an oxygen atom that hasan atomic number of 8?
The atomic number of an element _is_ the number of electrons in one of its atoms. Indeed, a sample of an element can be defined as any combination of atoms with the same atomic number. Oxygen is the element with atomic number 8. It is the element whose atoms have 8 electrons in their neutral state (and 8 protons).
What is the chemical symbol for an element whose atoms have 11 electrons?
For an neutral element that has the same number of electrons and protons, the element with 11 electrons is Na, sodium.
What is the element whose atom has 8 electrons when neutral?
The number of electrons corresponds to the "index" number of the element in the periodic table. The 8th element is Oxygen, which has 8 atoms when neutral. That didnt answer the question. ANSWER Neon has 8 electrons :)
A family of unreactive element whose atoms do not gain lose or share valence electrons?
Noble Gasses.
A substance whose atoms all contain the same number of protons and the same number of electrons are?
An element is a substance whose atoms all contain the same number of protons and the same number of electrons. The number of protons in an element's atom determines its atomic number and defines its chemical identity.
What is the atomic mass of an element whose atoms consist of eight protons nine neutrons and eight electrons is?
The Atomic Mass is 17
What is an element whose atoms contain 4 electrons in the second energy level?
Carbon. Carbon is in the second period, so it has electrons in its second energy level, and it is in the fourth group in the second energy level, so it has 4 electrons.
What is an element whose atoms can form a covalent bonds with another atom of the same element called?
The answer expected here is non-metal, and examples are carbon, chlorine, sulfur phosphorus. Metals have metallic bonds. However there are compounds where atoms of a metallic element form covalent bonds to other atoms of the same element.
