How is the charge of the atom or ion determined from the number of protons neutrons and electrons present?
Atoms have protons, neutrons, and electrons. Protons and electrons have electric charge, but neutrons do not. Protons are positively charged, and electrons are negatively charged. An atom has the same number of protons and electrons. Because the atom has same amounts of positively and negatively charged particles, the atom is neutral and has no electric charge. The only time an atom becomes electrically charged is if it loses or gains protons or electrons to throw off the balance. For example, we know that hydrogen only has 1 proton, 1 neutron, and 1 electron. This hydrogen atom has not electric charge. Later on, the hydrogen atom gains a proton. This would mean that there is more positive charge than negative charge in the atom. The hydrogen atom is now electrically charged.

How many protons neutrons and electrons in potassium -43?
Potassium-43 has 19 protons, 24 neutrons, and 19 electrons. The number of protons and electrons is determined by the element's atomic number (which is 19 for potassium), while the number of neutrons is calculated by subtracting the atomic number from the isotope mass number.
How many protons neutrons and electrons in 40 Ar?
18 protons 18 electrons 22 neutrons
Is it true that the size of an atom depends on the number of electrons protons and neutrons present in the atom?
Yes, the size of an atom is primarily determined by the number of electron shells it has, which is influenced by the number of protons and electrons. The protons and neutrons, located in the nucleus, contribute to the mass of the atom but have negligible impact on its size.

What is the mass of an atom mainly determined by?
The sum of masses of protons, neutrons and electrons.
What determines the mas of an atom?
The mass of an atom is determined by the combined mass of its protons, neutrons, and electrons. Protons and neutrons are the primary contributors to the mass, while electrons have a negligible mass in comparison.
Why neutrons are present in an atom?
Protons have a positive charge, Electrons have a negative charge, and Neutrons have a neutral charge. Neutrons help to ground the charges of protons and electrons.
What particles are used to determined the mass of an atom?
Mass of an atom = mass of protons + mass of neutrons
The atomic mass is determined by the weight of?
The number of protons, neutrons and electrons.
The atomic mass of an atom is determined by the combined masses of its what?
The atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. While electrons contribute very little to the atomic mass, the protons and neutrons, found in the nucleus, account for the majority of an atom's mass.
Are electrons smaller then protons and neutrons?
In their mass, that is about correct. The volume can not be accurately determined.
What is determined the mass of an atom?
The mass of an atom is determined by the sum of the masses of its protons, neutrons, and electrons. The protons and neutrons are located in the nucleus and contribute most of the mass, while the electrons, which have much less mass, orbit the nucleus. The mass of an atom is typically measured in atomic mass units (amu).
Where is the protons and neutrons found in the nucleus of a atom?
protons are present in the nucleus while electrons are present around the nucleus
How many protons neutrons and electrons are present in Mg2 and O2?

Atomic mass of an atom is determined by the combined masses of?
Atomic mass of an atom is determined by the combined masses of its protons, neutrons, and electrons. Protons and neutrons contribute most of the mass, as they are much heavier than electrons. The atomic mass is usually given in atomic mass units, where 1 unit is defined as 1/12 the mass of a carbon-12 atom.
