which particles determine the identity of an element
The particles that determine the identity of an element are the protons in the nucleus of an atom. The number of protons in the nucleus is known as the atomic number, which is unique for each element.
the subatomic particles that are lost gained or shared in chemical bonds are called
The subatomic particles that are lost, gained, or shared in chemical bonds are called electrons.
an atom is electrically neutral because
An atom is electrically neutral because the number of electrons in an atom is equal to the number of protons. Electrons have a negative charge, while protons have a positive charge. Since the charges of electrons and protons cancel each other out, the overall charge of an atom is neutral.
the nucleus of an atom has all of the following characteristics except that it
The nucleus of an atom has all of the following characteristics:
1. Positively charged: The nucleus is made up of positively charged particles called protons.
2. Dense: The majority of an atom's mass is concentrated in the nucleus, making it very dense.
3. Very small in size: The nucleus is significantly smaller in size compared to the overall size of the atom.
